The relationship between Hitler and his father, such as it was, could be described as minimal, if not nonexistent. Alois was a distant man at best, who believed in whipping his children for the slightest offense, which he believed would teach them discipline. He never called Hitler by name; rather when he summoned him, he did so by whistling, as one would call a dog, by placing two fingers in his mouth and uttering a loud whistle.
