**William Charles Waterhouse** (December 31, 1941 – June 26, 2016) was an American mathematician. He was a professor emeritus of Mathematics at Pennsylvania State University.^{[1]} His research interests included abstract algebra, number theory, group schemes, and the history of mathematics.^{[1]} He edited the 1966 English translation of Gauss's *Disquisitiones Arithmeticae*^{[2]} and was the author of the textbook *Introduction to Affine Group Schemes*.^{[3]}

In both 1961 and 1962, Waterhouse (at that time an undergraduate at Harvard University) earned a Putnam Fellowship as one of the top five competitors on the William Lowell Putnam Mathematical Competition;^{[4]} with his 1962 performance, he led his school to a third-place team award.^{[5]} He received his Ph.D. in 1968 from Harvard, for work on abelian varieties under the supervision of John Tate,^{[6]}^{[7]} and took a faculty position at Cornell University.^{[7]} In 1975 he moved to Penn State.^{[7]}

Waterhouse has won the Lester R. Ford Award of the Mathematical Association of America twice, in 1984 for his paper "Do Symmetric Problems Have Symmetric Solutions?"^{[7]} and in 1995 for his paper "A Counterexample for Germain".^{[8]}

## Personal life

Waterhouse died on June 26, 2016, in State College, Pennsylvania.^{[9]}
