John Von Neumann was a Hungarian mathematician of Jewish origin who was naturalized American in the 1930s. Born December 28, 1903. Developed major contributions in Quantum Mechanics, Set Theory, Computer Science, Economics, Game Theory, and virtually every area of Mathematics. He died on February 8, 1957, the victim of a brain tumor. He was also a professor at Princeton University and one of the builders of ENIAC (the first electronic computer).
Von Neumann was the oldest of the three children in the family and born under the name of Neumann János Lajos Margittai in Budapest. He was the son of Neumann Miksa (Max Neumann), a bank lawyer, and Kann Margit (Margaret Kann). At the age of 3, he could memorize most of the phone numbers of almost every member of his family, and at 6 he told his father Greek jokes.
John Von Neumann is known primarily for having formalized the logical design of a computer. In his proposal, he suggested that instructions be stored in computer memory. Until then they were read from punched cards and executed one by one. Storing them in memory, then running them, would make the computer faster, since at the time of execution, instructions would be obtained with electronic speed. Most computers today still follow the model proposed by von Neumann.
This model defines a digital sequential computer in which information processing is done step by step, characterizing a deterministic behavior (ie, the same input data always produce the same response).
