Three generations of the Kann family lived in spacious apartments above the Kann-Heller offices in Budapest von Neumann's family occupied an 18-room apartment on the top floor. John's mother was Kann Margit (English: Margaret Kann) her parents were Jakab Kann and Katalin Meisels of the Meisels family. Miksa's father and grandfather were both born in Ond (now part of the town of Szerencs), Zemplén County, northern Hungary. He had moved to Budapest from Pécs at the end of the 1880s. His father, Neumann Miksa (Max von Neumann, 1873–1928) was a banker, who held a doctorate in law. He was the eldest of three brothers his two younger siblings were Mihály (English: Michael von Neumann 1907–1989) and Miklós (Nicholas von Neumann, 1911–2011). Von Neumann was born in Budapest, Kingdom of Hungary, which was then part of the Austro-Hungarian Empire. In Hungarian, the family name comes first, and his given names are equivalent to John Louis in English. Von Neumann was born Neumann János Lajos to a wealthy, acculturated and non-observant Jewish family. Since 1968, it has housed the John von Neumann Computer Society.
Von Neumann's birthplace, at 16 Báthory Street, Budapest.
5.3 Technological singularity hypothesisĮarly life and education Family background. 5.1 Cellular automata, DNA and the universal constructor. 3.10 Mathematical formulation of quantum mechanics. As a Hungarian émigré, concerned that the Soviets would achieve nuclear superiority, he designed and promoted the policy of mutually assured destruction to limit the arms race. After the war, he served on the General Advisory Committee of the United States Atomic Energy Commission, and consulted for organizations including the United States Air Force, the Army's Ballistic Research Laboratory, the Armed Forces Special Weapons Project, and the Lawrence Livermore National Laboratory. He developed the mathematical models behind the explosive lenses used in the implosion-type nuclear weapon and coined the term "kiloton" (of TNT) as a measure of the explosive force generated. Also, my work on various forms of operator theory, Berlin 1930 and Princeton 1935–1939 on the ergodic theorem, Princeton, 1931–1932." ĭuring World War II, von Neumann worked on the Manhattan Project with theoretical physicist Edward Teller, mathematician Stanislaw Ulam and others, problem-solving key steps in the nuclear physics involved in thermonuclear reactions and the hydrogen bomb. In a shortlist of facts about his life he submitted to the National Academy of Sciences, he wrote, "The part of my work I consider most essential is that on quantum mechanics, which developed in Göttingen in 1926, and subsequently in Berlin in 1927–1929. His analysis of the structure of self-replication preceded the discovery of the structure of DNA. His last work, an unfinished manuscript written while he was in the hospital, was later published in book form as The Computer and the Brain. Von Neumann published over 150 papers in his life: about 60 in pure mathematics, 60 in applied mathematics, 20 in physics, and the remainder on special mathematical subjects or non-mathematical ones. He was a pioneer of the application of operator theory to quantum mechanics in the development of functional analysis, and a key figure in the development of game theory and the concepts of cellular automata, the universal constructor and the digital computer. Von Neumann made major contributions to many fields, including mathematics ( foundations of mathematics, functional analysis, ergodic theory, group 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 was generally regarded as the foremost mathematician of his time and said to be "the last representative of the great mathematicians". John von Neumann ( / v ɒ n ˈ n ɔɪ m ə n/ Hungarian: Neumann János Lajos, pronounced December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, computer scientist, engineer and polymath.
