Adolf Hitler was born on 20th April, 1889, in the small Austrian town of Braunau near the German border. Both Hitler's parents had come from poor peasant families. His father Alois Hitler, the illegitimate son of a housemaid, was an intelligent and ambitious man and was at the time of Hitler's birth, a senior customs official in Lower Austria. Alois had been married before. In 1873 he had married Anna Glasl, the fifty-year-old adopted daughter of another customs collector. According to Ian Kershaw, the author of Hitler 1889-1936 (1998): "It is unlikely to have been a love-match. Klara Polzl, Hitler's mother, left home at sixteen to to join the household of her second cousin, Alois Hitler. Franziska saw Klara as a potential rival and insisted that she left the household. The first of the children of Alois's third marriage, Gustav, was born in May 1885, to be followed in September the following year by a second child, Ida, and another son, Otto, who died only days after his birth.
