John Von Neumann (December 28, 1903 – February 8, 1957) was a pure and applied mathematician, physicist, inventor, and polymath. He made major contributions to mathematics (foundations of mathematics, functional analysis, ergodic theory, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, and fluid dynamics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.

Known for having an eidetic memory, he was able to memorize a column of the phone book at a single glance and was able to quote back a book verbatim, years after having read it only once.
