Mrs. Klára (Klari) Dán Von Neumann

A scientist, and a pioneer computer programmer, she wrote the code used on the MANIAC machine developed by John Von Neumann and Julian Bigelow at the Los Alamos Scientific Laboratory. She was also involved in the design of new controls for ENIAC and taught early weather scientists how to program. She wrote the preface to John von Neumann's posthumously published, influential Silliman Lectures, later edited and published by Yale University Press as "The Computer and the Brain". She was born in Budapest, Hungary in 1911, to K?roly - Karl D?n and Camila Stadler. She reportedly took her own life in 1963. She was married four times, including to John Von Neumann in 1938, and to Carl Eckart in 1958. She features significantly in computing historian George Dyson's book, Turing's Cathedral: The Origins of the Digital Universe, ISBN 978-0375422775. It is noted, that a Monte Carlo problem being coded, with Kl?ri Von Neumann?s assistance, as part of a hand-computed rehearsal conducted at Los Alamos in advance of running the problem on the ENIAC, now moved from the Moore School in Philadelphia to the Aberdeen Proving Ground.
