The oldest of three children, von Neumann was born J?nos Lajos Margittai Neumann (two given names, two surnames respectively) in Budapest to Neumann Miksa (Max Neumann), a lawyer who worked in a bank, and Kann Margit (Margaret Kann). Growing up in a non-practising Jewish family, J?nos, nicknamed "Jancsi", showed incredible memory at an early age, being able to divide eight-digit numbers in his head at the age of six. At the same age, when his mother once stared aimlessly in front of him, he asked, "What are you calculating?". J?nos was already very interested in math, the nature of numbers and the logic of the world around him. He entered the Lutheran Gymnasium in 1911. In 1913, his father purchased a title, and J?nos acquired the Austrian mark of nobility von, becoming J?nos von Neumann—J?nos was anglicised to John after he took up residence in the United States in the 1930s.
