# Harold Edwards (mathematician)

Harold M. Edwards ( born August 6, 1936 in Champaign ( Illinois)) is an American mathematician and historian of mathematics.

Edwards studied at the University of Wisconsin (Bachelor 1956) and at Columbia University (Master 1957). In 1961 he received his doctorate at Harvard University where he was subsequently Peirce Instructor. In 1962 he went to Columbia University, where he was assistant professor from 1963 to 1966. 1966 to 1969 he was an assistant professor at New York University, then to 1979 and associate professor from 1979 until his retirement in 2002 professor.

He was known primarily for two textbooks on number theory, which follow the historical- genetic method: Riemann 's Zeta Function (Academic Press 1974, with an English translation of Riemann's paper of 1859 ), a standard work, and Fermat 's Last Theorem - A Genetic Introduction to Algebraic Number Theory ( Springer, 1977), in which he follows the historical trace to Ernst Eduard Kummer, who developed the theory of ideals to solve the great Fermat's theorem. He has written numerous works on the history of mathematics published (in particular through grief, Richard Dedekind, Leopold Kronecker ). His book Advanced Calculus used systematically differential forms. In his book on linear algebra, and indeed in most of his books, he pursued an algorithmic, constructive approach.

In 1980 he won the Leroy P. Steele Prize. 1981/82 he was a Guggenheim Fellow. In 2005 he received the Albert Leon Whiteman prize of the American Mathematical Society. In 1978, he was with Bruce Chandler, the first editor of The Mathematical Intelligencer.

Edwards is married to the television journalist and author Betty Rollin and lives in New York City. He is a member of the New York Academy of Sciences. He is a Fellow of the American Mathematical Society.
