John von Neumann

John von Neumann  December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, computer scientist, and polymath. He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergonomic theory, representation theory, operator algebras, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.

Von Neumann's habilitation was completed on December 13, 1927, and he started his lectures as a privatization at the University of Berlin in 1928, being the youngest person ever elected privatization in its history in any subject. By the end of 1927, von Neumann had published twelve major papers in mathematics, and by the end of 1929, thirty-two papers, at a rate of nearly one major paper per month.His reputed powers of memorization and recall allowed him to quickly memorize the pages of telephone directories, and recite the names, addresses and numbers therein. In 1929, he briefly became a privatization at the University of Hamburg, where the prospects of becoming a tenured professor were better,but in October of that year a better offer presented itself when he was invited to Princeton University in Princeton, New Jersey.
