John Von Neumann (1903-1957) invented his celebrated "rings of operators" (called Von Neumann algebras) in the late 1930s, and also contributed to set theory, games theory, cybernetics (with his theory of self-reproducing automata, called Von Neumann machines), and the development of the atomic and hydrogen bombs.
He was born in Budapest and became an assistant professor of physical mathematics at Berlin University before moving to Princeton, USA, in 1929, where he later became professor of mathematics.
In the early 1940s he described a design for a stored-program computer.
