The oldest of three children, von Neumann was born Neumann János in Budapest to Neumann Miksa (Max Neumann), a banker, and Kann Margit (Margaret Kann). Growing up in a non-practicing Jewish family, von Neumann, nicknamed "Jancsi", showed incredible memory at an early age, being able to divide eight-digit numbers in his head at the age of six. He entered the Lutheran Gymnasium in 1911. In 1913, his father purchased a title, and Neumann János acquired the German name von, becoming János von Neumann.
From 1936 to 1938Alan Turing was a visitor at the Institute and completed a Ph.D. dissertation under von Neumann's supervision. This visit occurred shortly after Turing's publication of his 1934 paper "On Computable Numbers with an Application to the Entscheidungs-problem" which involved the concepts of logical design and the universal machine. Von Neumann must have known of Turing's ideas but it is not clear whether he applied them to the design of the IAS Machine ten years later.
Von Neumann had a mind of great ingenuity and near total recall. He was an extrovert who loved drinking, dancing and having a good time. He had a fun-loving nature with a great love of jokes and humor. He died in Washington D.C.
The John von Neumann Theory Prize of the Institute for Operations Research and Management Science (INFORMS, previously TIMS-ORSA) is awarded annually to a individual (or sometimes group) who have made fundamental and sustained contributions to theory in operations research and the management sciences.
