During the Nazi period of government (1933�1945), Adolf Hitler, enthusiast of new technologies and means of production, invested millions in scientific research and development centers, with the hiring of renowned engineers and scientists, and the creation of new industries. German society was also undergoing profound changes and new products were launched to meet its needs.

Quickly, the German army became one of the most advanced in the world, possessing more technological weapons, lethal rockets and airplanes that flew faster than any other ever created. Due to superior technological power, Hitler believed he would be the great winner of World War II.

Nazi Germany was defeated, but its achievements and scientific discoveries were taken by the Allied countries and influence the way we live until today. Scientific research, which used thousands of prisoners as guinea pigs, were utilized to created new medicines, objects made to show Nazi Propaganda were used as reference for the creation of new technologies and products created for consumption, during wartime, are available in every supermarket still nowadays.

This eBook aims to present 31 inventions from the Nazi period that changed the world. In addition, as a bonus of this edition, we will be presenting three Nazi projects that were not completed but could have changed the history of the war.

The Pernkopf Atlas, or Topographic Anatomy of Man, is a book on human anatomy created by Eduard Pernkopf from the bodies of Jews, gays and Gypsies killed by the Nazi regime. The book is still considered the best guide to human anatomy ever produced, with copies currently costing a few thousand dollars. Although its superior quality cannot be questioned, the book�s findings came from the bodies of thousands of people killed, cut and dissected by the Nazis, generating a great ethical discussion of their use.

Eduard Pernkopf, an Austrian professor and physician, was an active supporter of Nazism and was led to occupy the Dean�s position of the University of Vienna�s medicine faculty, because of his contacts with Nazi politicians. Pernkopf fired all Jews� colleges, including three Nobel Prizes, as soon as he took office.

In the first edition of the book, published in 1937, the signatures of the illustrators included swastikas, in addition to the two ray symbols of the SS Schutzstaffel, the paramilitary force of the Nazi Party. In 1939, a new Nazi government law determined that executed prisoner bodies should be immediately sent to the nearest anatomy department for research and teaching purposes. Pernkopf began receiving large numbers of bodies and worked 18 hours a day, dissecting corpses, while a team of artists created the images for future editions of the atlas.

Pernkopf was arrested after the war and fired from the university. He was held in a prison camp for three years. After his release, he managed to return to university and continued his work in the atlas, publishing a third volume in 1952. He died in 1955, while planning the fourth edition of his atlas.

Due to the large number of corpses that Pernkopf had access during the period that the Nazi Party ruled over Germany, its atlas has achieved unparalleled quality in illustrations and richness of detail, selling thousands of copies in several languages and is still today considered an exceptional piece of art, incomparable in precision and the best anatomical guide ever created.

On the other hand, the bloody source of each illustration is subject of discussion among academics and doctors around the world. Many teachers and doctors have stopped using the Pernkopf Atlas because they do not find it ethical to consult material produced with victims of the Nazi regime. Others claim that the atlas is still very relevant and that if its use save lives, then the best decision is to use it, but never forgetting that the ones responsible for its accomplishment was not Pernkopf, but the victims of Nazism.

The Ar234 Blitz (Lightning) was the world�s first functional turbojet bomber aircraft, created by the German company Arado during World War II. Developed from Luftwaffe specifications, the German aeronautics, it was the first autopilot aircraft, besides having also a parachute system.

Originally, the design of the Ar234 Blitz creates a lightweight turbojet-powered airplane, type of the engine was created in the 1930s, for use in recognition missions. However, during the war, aircraft received weapons and was also used in bombing missions. Single-person pilot and weighing just 5200 kg, the Ar234 Blitz maximum velocity was at 700 km/h, able to reach 1560 km and carrying up to 1500 kg of bombs, impressive numbers for the time.

Only one model of the Ar234 has survived to this day. This aircraft is a variant of the bomber Ar234 B-2 Werknummer 140312 and was one of the nine Ar234 delivered to the British forces by the Nazi army when its defeat was imminent.

Einheitsempf�nger (Television receiver unit), also known as Volksfernseher (People�s TV), was an analog television signal receiver launched in 1939. The launch of the device was part of Adolf Hitler�s plan to use Nazi propaganda as a form of social control. Hitler, along with Joseph Goebbels, Minister of Nazi Propaganda, had already realized the persuasive power television possessed, as well as turning possible to creation of jobs in the set-up factories.

The Einheitsempf�nger was simplified to the maximum and operated with 50i fps system, 441 monochrome lines and had only one receiving channel, measures that aimed to keep the price of the device low. So, all German families could buy. It was used in military hospitals and government departments, but never had mass production due to the beginning of the World War II.

The signal received by the device, tuned from the factory, was emitted from the Berlin transmission tower, which was destroyed in an Allied attack in November 1943, rendering the devices obsolete. Only 8 models remain and are scattered in museums around the world.

Fanta soda, popular worldwide, was created during the German Nazi government. During World War II, a trade embargo was enacted against Nazi Germany, making the syrup used as the basis for Coca-Cola (Coke) production unavailable, posing a major problem for the German factory. To prevent the plant from closing, Max Keith, Coca-Cola�s chief operating officer in Germany, decided to create a new soda, which was created from other inputs found for sale.

The name Fanta was coined by one of the factory employees and alludes to the word �Fantasie�, fantasy in German. The flavors offered were created with inputs that were found for sale during the production period, such as fruit marc and whey, resulting in soft drinks of different flavors each period, the first being made from malt.

In 1943, more than 3 million cans of Fanta were sold in Germany. Most cans were used to give sweetness and flavor to soups and stews to replace sugar, which was rationed in the war.

After the end of World War II, Coca-Cola stopped making Fanta, relaunching the brand in 1955. The variety of flavors that were produced during the war period became part of the brand, with over 100 different flavors of Fanta have already been launched worldwide. The most consumed orange-flavored soda in the world was created in 1955, in Italy.

Interessen-Gemeinschaft Farbenindustrie AG (translating �Paint Industry Interest Group SA�) better known as IG Farben, was a company founded in 1925, after the merger of 8 German chemical companies. Although it was founded before the Nazi regime and had some Jewish partners, the company was created under strong nationalist sentiment and made substantial financial contributions to the Nazi Party in the early 1930s.

In 1932, a year before Nazi regime started, I.G. Farben created a group that became known as the Reichsf�hrer SS Circle of Friends, where party leaders and key supporters could talk about a variety of topics, especially racial supremacy theories and anti-Semitic ideas. I.G Farben has also initiated a dismissal process for all Jewish employees and partners.

Over the next few years, the company grew dramatically due to the German economic boom and the various contracts and support it received directly from the top ranks of the Nazi Party. When the war began in 1939, I.G. Farben was already the fourth largest company in the world.

In 1941, Heinrich Himmler, Reserve Army Commander and General Plenipotentiary for the entire Reich Administration, signed an order supporting the construction of an I.G. Farben plant near Monowitz concentration camp, part of Auschwitz concentration camp complex, in Poland occupied by Germany. In 1943, I.G. Farben had 334 facilities in occupied Europe, nearly half of its workforce of 330,000 men and women consisted on slave labor or recruits, including 30,000 prisoners from Auschwitz. The company made all Germany synthetic rubber and methanol, 90% of its plastics and �organic intermediates�, 84% of its explosives, 75% of its nitrogen and solvents, about 50% of its pharmaceuticals and about 33% of its synthetic fuel, generating billions in profits every year

Bayer group staff of I.G. Farben conducted medical experiments on concentration camp detainees in Auschwitz and in Mauthausen concentration camp. Patients were infected with typhoid fever, tuberculosis, diphtheria, and other illnesses, and then received the drugs the company was developing for treatment. As a result of the cruel experiments, most of the infected detainees did not resist and died.

Documents obtained after the end of World War II proved that I.G. Farben paid 150 Reichsmarks per patient, while the concentration camp administration requested 200 Reichsmarks per person. I.G. Farben even sent a letter to Rudolf H�ss, commander of Auschwitz, that the amount requested for the subject was too high. The experiments resulted in new vaccine and drugs being used to this day.

Between 1942 and 1945, a cyanide-based pesticide, Zyklon.B, was used to kill more than one million people, mostly Jewish, at the gas chambers in Europe, including the Auschwitz II and Majdanek extermination camps in the occupied Poland. The poison gas and the gas chamber project were provided by Degesch (Deutsche Gesellschaft f�r Sch�dlingsbek�mpfung ), a subsidiary of IG Farben.

At the end of World War II, the heinous crimes of I.G. Farben began to be discovered and many executives were convicted of committing war crimes. The company was found guilty and had its dismemberment decreed by the Allies. The Soviet Union agreed to receive as part of its war damage reparation payments, the majority of I.G. Farben�s assets, located in the Soviet occupation zone. The Western Allies decided to split the company in 1951.

Today, after several mergers and sales, the companies resulting from the dissolution of I.G. Farben are the multibillion-dollar giants AGFA, BASF, Hoechst AG (Sanofi-Aventis Conglomerate) and Bayer AG, which manufacture from chemicals products, medicines and paints to hospital machines, as so film and digital products.

J�germeister (pronounced YAY-guhr-my-stur), is a distilled alcoholic beverage composed of a blend of herbs, roots and fruits, created in 1935 by Curt Mast. Curt�s father, Wilhelm Mast, was a major vinegar maker in the town of Wolfenb�ttel, Germany. However, Curt has always been very curious about the manufacture of spirits and liquors, taking over the business a few years later and turning a company into the manufacturer of alcoholic beverages.

The name J�germeister means master hunter or hunting master and was an ancient working title, which was officially introduced during the Third Reich. Hermann G�ring, a German miltary, politician and leader of the Socialist Party of German Workers (Nazi Party), and regarded as Hitler�s successor, was named Reichsj�germeister (Master Reich Hunter).

Curt was a great hunter and businessman, apparently naming a drink from J�germeister using the G�ring title, since his image was very popular on the whole Reich. When the J�germeister was launched in 1935, its name was already familiar to the Germans, who sometimes called the product �G�ring-Schnaps�, something like a G�ring drink.

The fact is, because of this connection, J�germeister became very popular among Nazi soldiers of all ranks, who used a drink to lighten the cold, celebrate the victories and escape the depression and anxiety that battles caused.

Later, the company struggled to distant themselves of any connection with the Nazis, claiming that the drink was an old recipe from local hunters, which is the official story to this day.

Jerrycan or jerry can, are storage gallons made of pressed steel originally capable of storing 5 gallons of fuel. Jerrycan was created in the 1930s to be used by the German army. Its project has undergone several modifications and its main objective was to enable the fast supply for Nazi army vehicles, as well as being a safe way to store and transport fuel on missions.

Prior to the invention of jerrycan, fuel was stored in non-functional cans that took up a lot of space and made it difficult to fill vehicles.

In 1936, at the request of the German army, Eisenwerke M�ller & Co. based in Schwelm, Westphalia, developed and produced a pressed metal gallon and an �X� on its side, which served to stiffen and to be as an expansion joint for the gallon. The jerrycan is designed to require no funnels or hoses to fill, a soldier can carry two full or four empty gallons and it will withstand impacts and falls, without the risk of leakage or explosion. The project was approved and during the war period, 19 German companies focused on producing the jerrycans.

As simple as it sounds today, the Jerrycans were essential to many German battles and invasions, since one of the main advantages the Nazi military possessed was their vehicles and battle tanks being used in their famous military tactics Blitzkrieg (war-strike), which consumed too much fuel to occur. When Hitler decided to invade Poland, he ordered the companies to manufacture tens of thousands of jerrycans months earlier, because he knew he would need a large amount of fuel to be able to take over Polish territory in a short time.

The Allies realized the importance of the Jerrycans in Hitler�s strategy and created a project specifically to copy the German invention. After the war, the model was already widespread in several countries, which used jerrycans for military and civilian use. It is still a very popular model of gallon today and is used worldwide for storing water, fuel and other hazardous substances.

The Meillerwagen was a trailer used by Germany to transport V-2 rocket, to lift Brennstand missile, and to be a support for supply and preparations service of weapons launching, during World War II. The Peenem�nde Army Research Center designed the Meillerwagen and a Gollnow&Son company built it, using the supplied components. The Meillerwagen was assembled by Italian and Russian workers which were prisoners and had vehicle code number 102 among Nazi officers.

With just this vehicle, it was possible to move powerful missiles to strategic places near the target. After reaching the launching site, Meillerwagen transformed itself on the launching base, placing the weapon in the launching position with the aid of an ingenious and powerful hydraulic motor that it possessed. When the missile was at the launch position, the Meillerwagen also turned into a supply platform, since it was equipped with piping to supply liquid oxygen, ethyl alcohol, compressed nitrogen, compressed air or hydrogen peroxide.

With all the versatility it had, the Meillerwagen was considered a sophisticated equipment, which served as the basis for various military vehicle designs. Only 3 copies survive the war period and are located at museums in Australia, the United Kingdom and the United States.

The Messerschmitt Me 262, known as Schwalbe (swallow) in the fighter version, or Sturmvogel (storm bird) in the fighter-bomber version, was the first jet fighter to come into operational use in the world. It showed several advances in design and technology, being considered a formidable weapon of war by Axis members and the Allies.

The Messerschmitt Me 262 project started before the outbreak of World War II, in 1938, and was designed to create a plane that could fly with new turbine models that were being developed by BMW and Junkers, two German companies.

The model was a direct request from Hitler, who repeatedly visited the development sheds, placing orders and explaining his strategic vision. Hitler wanted a plane that was fast enough to escape enemy artillery and that could be equipped with bombs for defense missions, since he already foresaw a possible invasion of his territory.

Although it was a priority, the project suffered from many development issues, technical issues, and modifications, some made by direct requests from Hitler himself. Due to the complex system of assembly and setbacks, the first Messerschmitt Me 262 were officially delivered only in 1944, when Germany�s situation was already worsened, and its defeat was approaching.

The Me 262 fighter first appeared in combat was in October 1944, at the Kommando Nowotny, when the aircraft began attacking Allied bomber formations, making it the first jet fighter in history to go into operation. Even with all the manufacturing problems, the Messerschmitt Me 262 was far superior to anything that had ever been designed, reaching an incredible 900 km/h and being able to carry two large bombs of 500 kg and 250 kg each. Its lighter version, with only light weapons was used in various slaughter and recognition missions.

It was produced 1433 units of the Messerschmitt Me 262, but the Germans were only able to put into operation a little over 100 units due to operational problems, lack of fuel and properly trained pilots. Even so, the Messerschmitt Me 262 airplanes used shot down more than 700 Allied airplanes during the war and could have changed the history of the war if they were delivered a few years earlier. After the end of the war, the Messerschmitt Me 262 was widely studied and used for Allied countries to create new fighter jets.

G-series are a group of nervous agents created during the period of the German Nazi government. The G-series is so named because German scientists synthesized them for the first time. G-series agents are known as nonpersistent. All compounds in this class were discovered and synthesized during or before World War II, led by Gerhard Schrader, when he worked at the labs of IG Farben, while working on the creation of a more efficient pesticide then the existed ones.

Nerve agents are a class of organic chemicals that affect the mechanisms by which nerves transfer messages to organs and muscles. Poisoning by a nervous agent leads to death by asphyxiation or cardiac arrest within minutes, mainly due to loss of body control over the respiratory muscles. Some nerve agents are easily vaporized and the main way into the body is the respiratory system and can also be absorbed through the skin.

The G-series is the first and oldest family of nervous agents. The first nervous agent ever synthesized was GA (Tabun) in 1936. GB (Sarin) was discovered in 1939, followed by GD (Soman) in 1944 and, finally, the most lethal, GF (Cyclosarin) in 1949. During the period that Nazi government ruled Germany, hundreds of tons of G-Series agents were produced and stocked for use as chemical weapons. The production and storage of G-series nerve agents was prohibited by the UN Convention on the Prohibition of the Development, Production, Storage and Use of Chemical Weapons and its Destruction in 1993.

GA or Tabun (C₅H₁₁N₂O₂P), is an extremely toxic synthetic chemical compound. It is a liquid form and a slightly fruity smell. It is classified as a nervous agent because it interferes in a fatal way on the functioning of the nervous system. Tabun became the first known nervous agent after it was discovered by pure accident in January 1936 by German researcher Gerhard Schrader. Schrader was experimenting with a class of compounds called organophosphates that kill insects by disrupting their nervous systems to create a more effective insecticide for IG Farben, a conglomerate of the German chemical and pharmaceutical industry. After testing the new chemical, he had synthesized, Schrader discovered that Tabun, besides being a potent insecticide, was extremely toxic to humans.

A factory was built in Dyhernfurth (now Brzeg Dolny, Poland), in 1939, to initially produce bombs and air bombs using a mixture of Tabun and chlorobenzene called �Variant A�. In the second half of World War II, its name changed to �Variant B�, consisting of an 80:20 mixture of Tabun and chlorobenzene, designed for easier dispersion. The factory was destroyed by the Soviet army, which seized more than 12 tons of Tabun gas before it was used.

Because GA is much easier to produce than other G-series weapons, and the process is relatively broad, countries that have developed a nerve agent production capacity without advanced manufacturing facilities generally began producing GA.

GB or Sarin (CH₃P(O)(F)OCH(CH₃)₂) is an extremely toxic synthetic compound. It is on a liquid form, is colorless and odorless. Sarin exposure is lethal even at very low concentrations. Death can occur within one to ten minutes after direct inhalation, caused by asphyxia due to pulmonary muscle paralysis, unless antidotes are rapidly administered. Non-lethal dose absorption can lead to permanent neurological damage, even with currently available medical treatments.

Sarin was discovered in 1938 at Wuppertal-Elberfeld in Germany by Gerhard Schrader and other I.G. Farben scientists. The compound was named after its discoverers: Schrader, Ambros, Ritter and von der Linde.

In 1939, the German government received information about the formula and, after some testing, the German Army Chemical Warfare Department ordered the product to be manufactured and stocked for use as a chemical weapon, mainly because of its high volatility (its easiness which the liquid can turn into gas).

After the end of World War II, both the Soviet Union and the United States manufactured large quantities of Sarin for use as a chemical weapon.

GD or Soman (C₇H₁₆FO₂P) is an extremely toxic synthetic chemical compound. It is on a liquid form, is corrosive and has a slight odor of rotten fruits. It is both more lethal and more persistent than Sarin or Tabun, but less than Cyclosarin.

At the summer of 1944, Soman was synthesized by the Nobel Prize winner Richard Kuhn, in conjunction with Konrad Henkel, through the collaboration and studies of Gerhard Schrader, during a research on pharmacology at the Kaiser Wilhelm Institute for Medical Research, in Heidelberg. This research was commissioned by the German army, which was interested in the development of new chemical weapons. Soman was produced in small quantities at a pilot plant at I.G. Farben plant, at the city of Ludwigshafen.

Soman causes devastating effects on the central nervous system (CNS), and can kill a healthy adult in minutes. In addition to the direct toxic effects on the nervous system, people exposed to Soman can suffer long-term effects, most of which are characterized by psychological problems. Individuals who were exposed to a small dose of Soman suffered severe toxic effects; once treated, they often developed depression, had antisocial thoughts, were withdrawn and subdued, slept restlessly, and had nightmares.

GF or Cyclosarin (CH₃P(O)(F)OC₆H₁₁), is an extremely toxic synthetic chemical compound. It is a liquid form of low viscosity, is flammable and has a mild sweet peach smell. It is the most lethal chemical compound of the G-series agents. Cyclosarin is a persistent liquid, which means it has low vapor pressure and therefore evaporates slowly, about 69 times slower than Sarin and 20 times slower than water, so its persistence can be noticed for a month.

Cyclosarin was developed from the beginning to be an extremely lethal chemical weapon to supplement the Wehrmacht�s arsenal. Inhalation of Cyclosarin takes only a few seconds to cause permanent damage to the central nervous system. It has the highest toxicity among all G-series components, requiring only 0.6 grams to kill a healthy adult human.

Cyclosarin has a more complex and expensive manufacturing process, so it was never produced in large quantities during World War II.

Methadone is a substance of the opioid group, used primarily to treat heroin addiction and other opioids, as well as being used to control chronic pain. Pain-relieving effects last about six hours after a single dose, and it is possible a period of up to 24 hours in the body. Methadone is usually administered orally and rarely by injection into a muscle or vein. Its chemical formula is C₂₁H₂₇NO. Methadone is virtually identical to morphine and acts on the same receptors as heroin.

Methadone was developed in 1937, in Nazi Germany, by scientists working for I.G. Farben They sought to create an opiate from readily available precursors to solve the problem of opium shortages and other painkillers due to the economic embargoes that rival countries had imposed on Germany. The drug was used in the military and it was discovered that there was a risk of causing dependence, besides having a high toxic degree, so its use was restricted.

After the war, all German patents, trade names and research records were requested and expropriated by the Allies. I.G. Farben research records were confiscated by official US government agencies. The committee report noted that while methadone was potentially addictive, it produced less sedation and respiratory depression than morphine and was therefore interesting as a commercial drug. The drug was launched on the market by several different laboratories over the following decades, being produced and marketed to this day.

Anti-Ship Missiles (AShM) are guided missiles designed for use against ships and large vessels. They can be fired from ships, airplanes or from the ground.

Anti-ship missiles were the first types of short-range guided missiles used during World War II. German air force, Luftwaffe, used the Henschel-Hs 293, FritzX and other missiles, all launched from their bombers, to cause serious damage to various Allied vessels, particularly in the years 1943 and 1944.

Most anti-ship missiles fly near the sea, are subsonic, and use a combination of inertial navigation system and radar scanning. Other anti-ship missiles use infrared to track the heat emitted by a ship or are guided by radio waves.

After the end of World War II, anti-ship missile technology evolved rapidly, increasing its range, speed, and destructive power. Today, many nations have their own anti-ship missiles with their own lethal characteristics.

Anechoic plates are plates made of polymer or rubber, containing thousands of small holes all over their surface and were added to military submarine hulls.

They have two main functions:

1.�Absorb the sound waves emitted by enemy sonar, reducing and distorting the feedback signal, causing the accuracy and range of the enemy sonar to be compromised.

2.�Decrease the sound emitted by the vessel itself and its engines to reduce the range at which it can be detected by enemy sonar.

The anechoic plates were developed by Kriegsmarine, navy of Nazi Germany, during World War II. They were known as Alberich, the name of an invisible dwarf of Germanic mythology.

After the end of World War II, anechoic plates were studied and used by several countries, including the Soviet Union and the United States, to upgrade their military vessels. Currently, anechoic plates are still used by various military vessels, music studios, soundproofing projects and the creation of anechoic chambers.

Chipboard wood is a material made up of a mixture of wood waste, such as dust and sawdust, glue and resin. This mixture is pressed, forming panels that can receive any type of coating, giving color and a smooth surface. It is generally used in the manufacture of low-quality furniture. Its advantage is its low cost and ease of manufacture as it can be made with wood scraps, sawdust and shavings.

Although a simpler version was created in 1887 in Germany, it was in the period of World War II that the Germans created the sturdy resin-based chipboard that is manufactured to this day. During this period, the production and use of the material increased sharply, as the German population suffered from several hardships, including quality wood, which was expensive and used mainly for military purposes.

The inventor Max Himmelheber, who was also a pilot of the Luftwaffe, produced the first chipboard sheets, which were little more than sawdust, wood chips and resin. The first commercial piece was produced during World War II at a factory in Bremen, Germany. The material has evolved over the years and is still used around the world today, avoiding cutting millions of trees and helping to recycle discarded furniture and wood objects.

Plankalk�l is a programming language created by Konrad Zuse between 1942 and 1945. It was the first high-level programming language to be designed for a computer. �Kalk�l� means formal system, so Plankalk�l means �formal system for planning�.

Konrad Zuse had created some computers with electromagnetic relays, and in 1938 built the Z1 computer (we�ll talk more about it in this eBook). When he finished his project, he realized the need to create a logical language based on propositional calculus. He decided to create the Plankalk�l language as part of his doctoral dissertation, developing a formal notation system for algorithms that could manipulate linear, branched and in loop calculus planes, which was very sophisticated and complex for the time.

Due to the collapse of Nazi Germany in 1945, Konrad Zuse was unable to submit his creation to the PhD, but had the language developed and recorded in a never released book.

After the end of World War II, Konrad Zuse published some scholarly articles in 1948, but didn�t received the prestige that his invention deserved. In the 1970s, with the advancement of computer processing, Plankalk�l was published and compiled, being relaunched by students at the Free University of Berlin, in 2000, for academic purposes.

The Olympic Torch Relay is the event of leading the Olympic flame from the city of Olympia, Greece, to the city where the Olympic Games will be held. The relay was first held at the Berlin Games in 1936 and continues to this day.

The torch relay was idealized and executed with great care by the Nazi Party to project the image of the Third Reich as a modern, economically dynamic state with growing international influence. The organizer of the 1936 Games, Carl Diem, drew on the tradition the Greeks held in 80 B.C, as an attempt to connect the ancient Olympics to the Third Reich.

Hitler, a great connoisseur of classical art, had the Nazi belief that classical Greece was a forerunner of the Aryan lineage and of the Germanic people, and projected it in all the symbolism and novelty that the relay brought as a way of showing the world this connection. Although the event was a Nazi propaganda, it was very well received by the public, being incorporated into all subsequent games.

The 1936 Olympic torch relay was held in 8 days by 3422 torchbearers, traveling through the cities of Olympia, Athens and Thessaloniki, in Greece, Sofia, in Bulgaria, Belgrade in Yugoslavia (now Serbia), Budapest in Hungary, Vienna, in Austria, Prague, in Czechoslovakia (now Czech Republic), Dresden and Berlin, in Germany.

The FuMG 38G Seetakt (Funkmessger�t) radio measuring device was one of the first Kriegsmarine naval radars, in World War II.

Hans Erich Hollmann, an electronic specialist, began working in the late 1920s in the microwave field, which would become the basis of most radar systems. He was especially interested in using microwaves for informational techniques, along with his research partner Hans-Karl von Willisen. They were also interested in the field of radar-like systems.

In 1934 Hans Erich Hollman, Hans-Karl von Willisen, and Paul-G�nther Erbsl�h founded a company called GEMA m.b.H., which, in the fall of 1934, built the first commercial radar to locate ships. The radar worked at a wavelength of 50 cm and was able to locate ships within a maximum distance of 10 km. In 1935, following Kriegsmarine�s requests, they developed an impulse radar and were able to locate the K�nigsberg light cruiser at 8 km of distance and with an accuracy of 50 m, which was enough to set the ships� firing direction. The same system was able to locate a plane 28 km away and 500 m high. Military utility did not go unnoticed: a terrestrial version called Freya was developed, while naval versions was called Seetakt.

In January 1938, the first mass-produced device, which operated at a wavelength of 60 cm and a frequency of 500 MHz, was installed on the Admiral Graf Spee cruise. Seetakt radar at Graf Spee could locate naval targets 25 km away, which put Kriegsmarine well ahead of the British Navy and the US Navy in terms of using radar on their ships. During World War II, about 200 Seetakt radars were produced, placed on surface vessels, submarine and at shore for coastal defense.

The acoustic torpedo was a powerful and vital weapon for many battles of the Nazi army in the Atlantic Ocean. The acoustic torpedo, unlike the conventional torpedo, has the ability to alter its trajectory upon launch and move toward the noises that boats and submarines make underwater while navigating. Using a sonar and special receivers to pursue its target, the acoustic torpedo was an effective and deadly weapon.

The first model of acoustic torpedo was the G7e/T4 Falke created in early 1943 and was not widely used in battle. Everything changed in August of the same year with the introduction of the new G7esT-5 Zaunk�nig acoustic torpedo model. Much faster and more advanced than Allied models, the new torpedo was critical to the success of several attacks on merchant ship convoys during the Battle of the Atlantic.

The Battle of the Atlantic was the longest continuous military campaign of World War II, which ran from 1939 until the defeat of Nazi Germany in 1945. It was an important part of World War II naval history, peaking from the mid-1940s until the end of 1943.

Vergeltungswaffe (�retaliatory weapons�, �reprisal weapons�), also known as V-Waffen (�Weapon-V�), were a particular set of long-range artillery armaments designed by the Nazi military for strategic bombing missions during World War II. Originally, each project had a different military code, but their names were changed by determination of Nazi Propaganda Minister, Joseph Goebbels, creating an identity and purpose for the weapons at a time when Germany suffered from Allied bombing. The V-Waffens was be the weapons that would give avenge to the German people.

The Vergeltungswaffens included the V-1, a pulse jet powered cruise missile; the V-2, a liquid-fuel ballistic missile and the V-3 cannon. All of these weapons were designed for use in a military campaign against Britain, although only V-1 and V-2 were used in a campaign conducted between 1944 and 1945.

After the invasion of Europe by the Allies, these weapons were also used against targets on the European continent, mainly in the cities of London, in United Kingdom, Antwerp and Li�ge, in Belgium and some regions of France.

The V-Waffen were used not only against military personnel but also against civilian targets, especially in the London area and southern England. The aim was to retaliate for the destruction of German cities by British and American bomber squads. As happened on the Allied air strikes, many civilians were severely affected. In the later stages of the war, the V-Waffen were, mainly, used for attacks aiming to disrupt the supply of Allied troops on the Western Front.

The Vergeltungswaffe 1 (�Vengeance Weapon 1�) or V-1, was a missile of long-range and aircraft-shaped developed for bombing and retaliation missions, by the Luftwaffe. It is considered the first guided cruise missile in history and was known among allies as buzzbomb, due to the noise it produced.

The V-1 missile had a total length of 7.90 m and a wingspan of 5.38 m, reaching up to 230 km with a top speed of 640 km/h. It was a rather complex device for the time: at spherical containers, the compressed air was use as a gyro compass to make automatic course corrections; to determine distance traveled, a small propeller at the top guided a counter, which set the trigger upon reaching a predefined distance, making the missile to point downwards; an impact fuse detonated the explosive charge, an 850 kg warhead. But the V-1 had problems with its accuracy and because it flew in a straight line, its trajectory was known, allowing the Allied intercept action.

From June 1944 to March 1945, approximately 12,000 V-1s were used by the Wehrmacht, primarily against targets in England (London) and Belgium (Antwerp Harbor). The last enemy action of any kind on British soil occurred on March 29th, 1945, when a V-1 struck Datchworth, in Hertfordshire.

The Vergeltungswaffe 2 (�Vengeance Weapon 2�) or V-2, was the world�s first long-range guided ballistic missile. The missile, powered by a liquid-propelled rocket engine, was developed during World War II in Germany as a �weapon of revenge� designed to attack Allied cities in retaliation for Allied attacks against German cities.

The V-2 rocket also became the first artificial object to travel into space, crossing the K�rm�n line, which defines the boundary between the earth�s atmosphere and outer space, with the vertical launch of the MW18014, on June 20th, 1944.

The V-2 used a mixture of fuel alcohol and liquid oxygen, which were injected into very high-pressured combustion chambers. It also had a second propellant that worked with a mixture of hydrogen peroxide, sodium permanganate and water. With this, the V-2 reached a top speed of 5700 km/h, reaching over 200 km in height and being able to travel up to 360 km.

Beginning in September 1944, more than 3,000 V-2s were launched by the Wehrmacht against Allied targets. The V-2 attacks are estimated to have killed about 9,000 civilians and military personnel, and another 12,000 forced workers and concentration camp prisoners died as a result of their forced participation in weapons production.

After the end of World War II, scientists who worked on the construction of the V-2 were arrested by the United States and the Soviet Union. Both countries aimed to use the V2 rockets, very sophisticated for the time, as the basis of their respective space projects. Wernher von Braun, chief engineer and projector of the Nazi rockets, received a proposal to work on the development of American rockets. The first photo taken in space was taken by a V-2 rocket on October 24th, 1946. Wernher von Braun was also primarily responsible for the Saturn V Lunar Rocket, used at the Apollo Missions, to send mankind to the moon.

The Vergeltungswaffe 3 (�Vengeance Weapon 3�) or V-3, was a fixed cannon created by the Wehrmacht, and operated on the multi-load principle, where secondary explosive charges were applied to the moving projectile to increase its speed.

The concept of the V-3 was developed from the Paris Gun, also called the Kaiser Wilhelm Gesch�tz, a long-range rail cannon created by the Germans in 1918, to bomb Paris during World War I.

In 1942, the Paris Gun project attracted the attention of August C�nders, a renowned German engineer. C�nders felt that the gradual acceleration of the casing by a series of small loads scattered across the barrel length could be the solution to the problem of designing long-range weapons that could hit the target with acceptable accuracy. The strong explosive charge to launch high-speed projectiles was causing very rapid degradation of conventional weapon tubes. The project intended to use two V-3 batteries to crush London under a flood of hundreds of 140 kg (310 lb.) projectiles with a 25 kg (55 lb.) explosive charge.

The first V-3s that would attack London began to be built on bunkers in the Pas-de-Calais region of northern France but were rendered unusable by Allied bombing before their completion. Two similar weapons were used to bomb Luxembourg from December 1944 until February 1945. There were other proposals to deploy batteries to bomb London, Paris, Antwerp and other cities, but they were not implemented due to the poor condition of the German rail network and the lack of ammunition. Disassembled gun tubes, spare parts and ammunition that remained after the end of the war were later captured by the US Army and discarded in 1948.

Volksempf�nger (�Receiver of the People�) were some models of radio receiver developed by engineer Otto Griessing, following the request of Nazi Propaganda Minister, Joseph Goebbels. The goal of the Volksempf�nger program was to create a method of direct contact between the Nazi government and the people, because Joseph Goebbels realized the radio�s great propaganda potential.

Goebbels� goal was that every German house could have a Volksempf�nger, so the initial challenge was to make a cheap device. As consequence of the low cost, it generally did not have shortwave bands and did not follow the common practice at the time of marking the approximate dial positions of major European stations in line with them. Only German and Austrian stations were marked. Sensitivity was limited to reduce further production costs, as long as the device received the Deutschlandsender and the Reichssender, public national networks of regional radio and television active from 1925 to 1945, used to run Nazi propaganda.

During the war years, listening to foreign stations became a crime in Nazi Germany, while in some occupied territories it was strictly forbidden to listen to any radio station. The penalties ranged from fines and confiscation of radios to, especially at the end of the war, sentencing to a concentration camp or the death penalty. Even with the risk, clandestine transmission and listening was widespread in many Nazi-occupied countries and Germany itself.

The Volksempf�nger, like the entire Nazi propaganda strategy, was very effective as a tool for spreading ideas and social mobilization. Hitler�s Armaments and War Production architect and minister, Albert Speer, said in his final speech at the Nuremberg trials:

Volkswagen (�Car of the People�) is a German carmaker founded as Gesellschaft Zur Vorbereitung des Deutschen Volkswagen, GmbH (�Society for the Production of the German Popular Automobile�) on May 28 th, 1937 by the German Labor Front, a Nazi labor union, based in Wolfsburg.

Volkswagen was created as part of a Nazi government plan to industrialize the country, creating jobs for a devastated Germany after losing World War I. Adolf Hitler was a declared devotee of Henry Ford�s work, and he saw in his automobile production line the key to producing cheaper cars that could be bought by all German families. At that time only 1 in 50 Germans owned a car, which was considered a luxury good. Another point of interest in the creation of Volkswagen was to pass on a modern country image to the world and use the history of industry creation to strengthen Nazi propaganda. To this end, the government has even created a new city to be the headquarters of Volkswagen, initially named Stadt des KdF-Wagen, now Wofsburg.

During the Nazi government Hitler visited the Volkswagen plant several times and was directly active during the development and production of the automaker first model in line, the Volkswagen 1 or KdF, known in the United States as Beetle.

German historians have estimated that 80% of Volkswagen�s workforce in the war years was of slaves, much of it practiced in many Nazi Germany production plants. Many of the slaves would have been killed by exhaustion or as punishment for low production.

Following the defeat of Germany between 1945 and 1948, the control of the automaker went to the hands of British army war officer, Major Ivan Hirst. Hirst, who was also an engineer, believed that the survival of German industry was vital to rebuilding the country and averting a new war. He was fully committed to the recovery of Volkswagen, managing to close contracts with the British government, rebuilding the factory, recreating manufacturing processes and developing new projects. In 1949 Major Hirst left the company - now remodeled as a fund controlled by the West German government and the Lower Saxony State government. Volkswagen now belongs to the German people, which is still a shareholder of the company.

The Volkswagen 1 or KdF, was the first car produced by the German automaker Volkswagen. Designed by Ferdinand Porsche during the 1930s, it was created to fulfill a direct request from the F�hrer Adolf Hitler. In the United States, he is known as Beetle.

The story of the creation of the KdF is directly linked to the Volkswagen creation project, as the automaker was created to specifically produce the �German�s car of the people�. Adolf Hitler had the ambitious plan to rapidly industrialize Germany and idealized the design of a popular car as a great opportunity. At the time, less than 1 million cars were driving around the German country, while in the United States, the number of cars circulating was an incredible 25 million units.

The project leader was Ferdinand Porsche, who was well known for creating fast and powerful car models. Porsche, who had already been working on a cheaper car project, received clear and direct instructions from Hitler: the new car should be able to carry two adults and three children, reach 100 km/h (62 mph), be economical and cost-effective, so every German family could have one.

Porsche took some ideas already tested on other models he designed, made some new ones and came to a car with an air-cooled rear engine, torsion bar suspension, rounded front hood for better aerodynamics and a �beetle� shape. During this period, the Nazi government invested public money in the construction of a new factory and sponsored the entire project in order to reduce costs.

The car of the German people was born, the KdF Wagen. KdF is an acronym for Kraft durch Freude (Power for Joy), a policy that preached increase of productivity, patriotism, and spreading the image of a modern German people. With the Nazi government-sponsored advertisements that read �Mark F�nf die Woche musst du sparen, willst du imigen Wagen fahren� (�Five marks a week you should set aside, if you want your own car�), KdF was a success, selling over 300.000 units before it was officially launched, in 1940.

After the war, as part of the Volkswagen and German recovery plan, the model was named to Kafer, was exported and produced in several countries, given different adaptations, changes and names, being produced until the 1990s and becoming one of the most iconic and best selling cars in history.

The ZG 1229 Vampir was the first active infrared night vision device developed. It was generally used by German soldiers with the Sturmgewehr44 assault rifle, during World War II.

The first night vision devices were introduced by the German army in 1939 and were being developed by AEG since 1939. The ZG 1229 Vampir weighed about 10 kg, carried two batteries, an image converter, a tungsten light source and a sensor-filter that allowed only infrared light to appear. The soldier wearing the device was known as the night hunter.

Vampir equipment was first used in combat on February 1945. 310 units were delivered in the final stages of the war. Similar infrared equipment was installed on MG34, MG42 machine guns and 50 Mark V.Panther tanks.

The Z-line computers were a group of four computers, created by Konrad Zuse during the years of the German Nazi government. Konrad Zuse was a German civil engineer, computer scientist, inventor, entrepreneur and computer pioneer.

The Z1 was a mechanical computer designed between 1936 and 1937 and built between 1936 and 1938. It was an electrically powered binary mechanical calculator with limited programming capability. The Z1 was the first freely programmable computer in the world that used Boolean logic and floating-point binary numbers. It was completed in 1938 and completely financed with private funds. This computer was destroyed by the bombing of Berlin in December 1943, during World War II.

The Z2 was a mechanical and relay computer concluded in 1940. It was an enhanced version of the Z1, using the same mechanical memory but replacing arithmetic and control logic with electrical relay circuits. Zuse introduced the Z2 in 1940 to members of the Deutsche Versuchsanstalt fur Luftfahrt�� DVL (German Air Force Research Institute). Photographs, plans and documentation for the Z2 were destroyed by Allied bombing during World War II.

The Z3 was a German electromechanical computer completed in 1941. It was the world�s first fully automatic programmable digital computer in operation. The Z3 was built with 2,600 relays and had a memory that stored 64 numbers of 22-bits. Its calculations were performed in binary floating-point arithmetic and already calculated square roots and performed a multiplication in about 5 seconds. The program code was stored in perforated film.

The Z3 was used to solve airplane wing vibration problems. Zuse asked the German government for funding to replace relays with all-electronic switches, but funding was denied during World War II, as this development was considered �unimportant to war�. The original Z3 was destroyed on December 21st, 1943. during a bombing of the Allies in Berlin.

The Z4 was the world�s first commercial digital computer, designed and built by Konrad Zuse in 1945. After the creation of the previous models, Zuse realized that he could create a company to market his Z models and created the Zuse Apparatebau. The Z4 was based on the Z3 design, but like the Z2, it was partially mechanical (memory) and electromechanical machine. A special unit called Planfertigungsteil (program building unit), which punctured program tapes, greatly facilitated the programming and correction of machine programs through the use symbolic operations and memory cells. The machine had a large repertoire of instructions, including square root, MAX, MIN, and sine.

To prevent it from falling into Soviet hands, the Z4 was evacuated from Berlin on February 1945 and transported to G�ttingen. The Z4 was completed at the Aerodynamische Versuchsanstalt AVA (Aerodynamic Research Institute) facility, which was located in the Lower Saxony region.
