Family Roots & Background Father –Neumann Miksa Mother – Kann Margit An extraordinary prodigy In 1913, his father was rewarded with ennoblement Family emigrated to the United States in the early 1930 s The oldest of three brothers János -> Johann ->John Austria-Hungary-born American

Contributions Quantum physics, functional analysis, set theory, topology, economics, computer science, numerical analysis, hydrodynamics (of explosions), statistics and many other mathematical fields as one of history's outstanding mathematicians. Most notably, von Neumann was a pioneer of the application of operator theory to quantum mechanics

Outstanding contributions in the areas of mathematics • Established theory of operator rings laid the mathematical foundation of quantum mechanics • Applied mathematics, in mechanics, economics , numerical analysis and have important contribution to the electronic calculator • Participated in the 1944 world's first electronic calculator design, • Proposed the Monte Carlo method in the development process of the atomic bomb

Greatest Achievements in the Life • Join the development plan for ENIAC computer in 1944 • A new general-purpose stored program computer program (EDVAC program) was born • EDVAC make up of calculator, logic control unit, memory, input and output five major components, and described the five most of the functions and mutual relations in the 101 page report • The era of electronic computer began.

Marriage & Death • Married twice • Mariette Kevesi in 1930 divorced in 1937 • Married Klara Dan in 1938 • One child, by his first marriage, a daughter named Marina Diagnosed with bone cancer or pancreatic cancer in 1957. Died within a few months of the initial diagnosis, in excruciating pain Fellow nuclear pioneer Enrico Fermi had died of stomach cancer

Life Events and Achievement at a Glance Von Neumann life Events • Issued by the Commission in 1937, American Mathematical Prize B • Joined in 1947 by the American Mathematical Committee Gibbs • 1951 -1953 served as the Chairman of Gibbs • 1947, 1956 annual President's Award twice (the Medal for Merit, the Medal for Freedom) • 1956 by the Albert Einstein Memorial Award, the same year Enrico Fermi Award Von Neumann's academicinstitutionshaveworked • Academia Nacional de Ciencias Exactas (Lima, Peru) • Academia Nazionale dei Lincei (Rome, Italy) • American Academy of Arts and Sciences (U. S. ) • American Philosophical Society (USA) • Instituto Lombardo di Scienze e Lettere (Milan, Italy) • National Academy of Sciences (USA) • Royal Netherlands Academy of Sciences and Letters (Netherlands, Amsterdam)
