Bernard Dwork

Bernard Morris Dwork (May 27, 1923 – May 9, 1998) was an American mathematician, known for his application of p-adic analysis to local zeta functions, and in particular for a proof of the first part of the Weil conjectures: the rationality of the zeta-function of a variety over a finite field. For this proof he received, together with Kenkichi Iwasawa, the Cole Prize in 1962. The general theme of Dwork's research was p-adic cohomology and p-adic differential equations. He published two papers under the pseudonym Maurizio Boyarsky.
Dwork received his Ph.D. at Columbia University in 1954 under direction of Emil Artin; Nick Katz was one of his students. He is the father of computer scientist Cynthia Dwork, who received the Dijkstra Prize and is now continuing as a Radcliffe Scholar at Harvard University. He received a Guggenheim Fellowship in 1964, and his other daughter, historian Deborah Dwork, received one in 1993. Additionally, his son Andrew Dwork works is a Professor of Clinical Pathology and Cell Biology (in Psychiatry), at Columbia University, focusing his work on neuropathology of psychiatric disorders.
