The Nazis sent doped-up soldiers to the front in Poland in 1939 and to France the following year. During the invasion of France, a whopping 35 million tablets of the methamphetamine Pervitin were distributed to soldiers, who named the miracle pill "Panzerschokolade" ("tank chocolate"). It wasn't just the Germans, however: the Allies gave their troops drugs, too.

A Japanese chemist created a liquid version of what was to become the German Wehrmacht's miracle pill. The Berlin-based drug firm Temmler refined the drug and took out a patent in 1937. A year later, Pervitin was sold over the counter. It left people alert, fearless, and without need of food or drink. Pervitin is still on the market - illegally - and under a different name: Crystal Meth.

Historians disagree over whether the Führer himself was addicted to Pervitin. Files kept by Hitler's personal doctor, Theo Morell, show a scribbled "x" in reference to a cocktail of medication he was given on any given day - but it isn't exactly clear what it refers to. We do know, though, that Hitler was on a mix of powerful drugs.

German chemists' inventive talents go back even further than the Nazi era, however. "No cough thanks to heroin," was the ad slogan for a cough medicine produced by the German drug company Bayer in the late 19th century. Heroin was prescribed to patients - adults and children - suffering from epilepsy, asthma, schizophrenia and heart disease. Any side effects? Bayer listed constipation.

Felix Hoffmann is perhaps best known for inventing Aspirin. But that's not all. He also developed heroin while experimenting with acetic acid. Hoffmann combined the acid with morphine, an extract from the poppy pod. Heroin was legal in Germany until 1971 when it was finally outlawed.

In 1862, the Darmstadt-based firm Merck started producing large amounts of cocaine as a local anesthetic for ophthalmologists. German chemist, Albert Niemann, had previously isolated an alkaloid he named cocaine from South American coca leaves. Niemann died shortly after discovering cocaine - of lung problems.

Sigmund Freud, an Austrian neurologist and the "father of psychoanalysis," consumed cocaine for scientific purposes. In his Cocaine Papers study, Freud described the drug as harmless. He observed "euphoria, more vitality and [a] capacity for work." His enthusiasm waned, however, after a friend died of an overdose. At that time doctors prescribed cocaine for headaches and stomach problems.

American chemist, Alexander Shulgin, is widely believed to have invented the party drug ecstasy. But in reality, he rediscovered the compound. The German firm Merck had originally developed and filed for a patent for a colorless oil under the name 3,4-Methylendioxymethamphetamine - MDMA - in 1912. Back then, chemists thought the substance had no commercial value.

These German chemists' inventions are still having an impact today. According to estimates by the United Nations about 190,000 people died worldwide in 2013 because of illegal drug consumption. However, alcohol, a legal drug, is responsible for far more deaths. The WHO says 5.9 percent of all deaths in 2012 were due to alcohol consumption - that's 3.3 million people.

As Hitler's Propaganda Minister, the virulently anti-Semitic Goebbels was responsible for making sure a single, iron-clad Nazi message reached every citizen of the Third Reich. He strangled freedom of the press, controlled all media, arts, and information, and pushed Hitler to declare "Total War." He and his wife committed suicide in 1945, after poisoning their six children.

The leader of the German National Socialist Workers' Party (Nazi) developed his anti-Semitic, anti-communist and racist ideology well before coming to power as Chancellor in 1933. He undermined political institutions to transform Germany into a totalitarian state. From 1939 to 1945, he led Germany in World War II while overseeing the Holocaust. He committed suicide in April 1945.

As leader of the Nazi paramilitary SS ("Schutzstaffel"), Himmler was one of the Nazi party members most directly responsible for the Holocaust. He also served as Chief of Police and Minister of the Interior, thereby controlling all of the Third Reich's security forces. He oversaw the construction and operations of all extermination camps, in which more than 6 million Jews were murdered.

Hess joined the Nazi party in 1920 and took part in the 1923 Beer Hall Putsch, a failed Nazi attempt to gain power. While in prison, he helped Hitler write "Mein Kampf." Hess flew to Scotland in 1941 to attempt a peace negotiation, where he was arrested and held until the war's end. In 1946, he stood trial in Nuremberg and was sentenced to life in prison, where he died.

Alongside Himmler, Eichmann was one of the chief organizers of the Holocaust. As an SS Lieutenant colonel, he managed the mass deportations of Jews to Nazi extermination camps in Eastern Europe. After Germany's defeat, Eichmann fled to Austria and then to Argentina, where he was captured by the Israeli Mossad in 1960. Tried and found guilty of crimes against humanity, he was executed in 1962.

A participant in the failed Beer Hall Putsch, Göring became the second-most powerful man in Germany once the Nazis took power. He founded the Gestapo, the Secret State Police, and served as Luftwaffe commander until just before the war's end, though he increasingly lost favor with Hitler. Göring was sentenced to death at Nuremberg but committed suicide the night before it was enacted.
