The Life of Adolf Hitler At 6:30 p.m. on the evening of April 20, 1889, he was born in the small Austrian village of Braunau Am Inn just across the border from German Bavaria. Adolf Hitler would one day lead a movement that placed supreme importance on a person's family tree even making it a matter of life and death. However, his own family tree was quite mixed up and would be a lifelong source of embarrassment and concern to him. His father, Alois, was born in 1837. He was the illegitimate son of Maria Anna Schicklgruber and her unknown mate, which may have been someone from the neighborhood or a poor millworker named Johann Georg Hiedler.
