John von Neumann (/ v ɒ n ˈ n ɔɪ m ən / von NOY-mən; Hungarian: Neumann János Lajos [ˈnɒjmɒn ˈjaːnoʃ ˈlɒjoʃ]; December 28, 1903 – February 8, 1957) was a Hungarian and American mathematician, physicist, computer scientist and engineer.
According to György Marx, the extraterrestrial origin of the Hungarian scientists is proved by the fact that the names of Leó Szilárd, John von Neumann, and Theodore von Kármán cannot be found on the map of Budapest, but craters can be found on the Moon bearing their names: [2] Szilard, Von Neumann, Von Kármán, and a crater on Mars, Von ...
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
In July 1943, Oppenheimer wrote to John von Neumann, asking for his help, and suggesting that he visit Los Alamos where he could get "a better idea of this somewhat Buck Rogers project". [145] At the time, von Neumann was working for the Navy Bureau of Ordnance, Princeton University, the Army's Aberdeen Proving Ground and the NDRC.
WEIZAC (Weizmann Automatic Computer) was the first computer in Israel, and one of the first large-scale, stored-program, electronic computers in the world. [1]It was built at the Weizmann Institute during 1954–1955, based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann and was operational until the end of 1963.
Fermi evokes his friend von Neumann who, when asking him how many arbitrary parameters he used for his calculations, replied, [1] "With four parameters I can fit an elephant, and with five I can make him wiggle his trunk." By this he meant that the Fermi simulations relied on too many input parameters, presupposing an overfitting phenomenon.

John von Neumann in the 1940s. Bill Hamilton was a solitary man who saw everything through the lens of Darwin's theory of evolution. He wanted to know why some ants and humans give up their life for others. In 1963, he realised that most of the behaviours of humans were due to genes, and he began looking at humans from the genes' point of view.
