But Hitler wasn't just another strongman. His personality had a profound influence on events. He was a mercurial gambler who thought primarily in the short term and maintained his power by encouraging chaos with his subordinates vieing for his favour. Change his early life and you change his personality.
Instead of becoming an artist, Hitler decided to pursue the goal in medical field.
Despite of becoming a physician, Hitler would probably be still drafted to the German military during WWI like in are timeline. However unlike in are timeline, due to his medical degree he was instead drafted to the Army Medical Service.
Throughout his school and military experience, Hitler’s grew more interest in medical research. Learning what was the origin of diseases and how the human body works.
After the war, Hitler went back to school and later earn a Master of Science in Medicine or Surgery. Also if he can’t attend school in Germany due to Hyperinflation, then he might attend schools somewhere in Europe, possibly Great Britain.
I honestly don't how he cured cancer, but let just presume he did.
For his achievements, Hitler was rewarded with the medal of honor, the knightly order, and other sort of rewards by various countries or organizations.
Fun fact: this scenario was completely inspired by one of the episode of Rick and Morty. Go check it out.
