Morell, Theodor - TracesOfWar.com

On May 26,1948, Theodore Morell, German doctor and Hitler's personal physician, died at the age of 61. He was referred as the
Reichsspritzenmeister, the state’s master of injections. From the article:

"Throughout the years, Morell administered more than sixty different drugs to Hitler. The Führer received a daily injection of some of them. It was not always clear which substances the drugs were made of but many believe that it affected both the rise as well as the downfall of Adolf Hitler. Morell administered a few substances to Hitler so often he must have become dependent on them, if not addicted to. These drugs contained opiates, codein and cocain. In 1936 amphetamines came on the market for the first time and Hitler could not keep his hands off them. In 1938, the King of Italy told his Minister of Foreign Affairs that Hitler was being injected with narcotics and stimulants. Morell had unlimited access to those substances. If Hitler actually had been addicted, it may well have affected his judgement and with it, the progress of the Second World War. The turning point of the war was the battle for Stalingrad. The progress of this operation is probably the best example of Hitler’s lack of sound judgment.

In 1943, Hitler’s complaints increased again. Possibly, the defeats at Stalingrad and in North-Africa contributed to this. Morell observed slight tremors in Hitler’s left arm and leg and clearly saw him dragging his left leg. Morell did not know exactly what caused it and was thinking about ‘brain fever’ (probably Parkinson’s disease). The doctor administered more and more drugs such as injections and pills with multivitamins under his own brand name Vitamultin. It is not unlikely that this drug, produced exclusively for Hitler, contained the stimulant pervitin. Pervitin is a meta-amphetamine which causes a sense of tirelessness and buoyancy. According to his adjutant Heinz Linge, before Hitler got out of bed each morning, he was given an injection by Morell which caused him to be alert, lively and so immediately fresh and ready for the day. Hitler’s reaction frequently was something like: 'Morell, you are my saviour, I do not know how I made it through the night but here you are my saviour, you have cured me.'"
