John von Neumann was born on December 28, 1903, in Budapest, Austria-Hungary. He died on February 8, 1957.
Von Neumann spent much of his early life in Hungary and later moved to New Jersey. He worked on the EDVAC project for which he wrote programs and collaborated with Alan Turing on the philosophy of artificial intelligence.
Von Neumann also consulted for the Army's Ballistic Research Laboratory on the ENIAC project. The architecture that von Neumann wrote for the ENIAC became the basis of most modern computer designs and led to "stored-program" computers. In his architecture data and programs are stored in the memory.
During World War II he helped create the atom bomb. He also wrote the book The Computer and the Brain.
One interesting fact about von Neumann is that he was a notoriously bad driver and often drove while reading a book, resulting in numerous accidents and arrests.
