Life and career
editBorn in Chicago, Illinois, he attended the Illinois Institute of Technology and the University of Chicago, earning a B.S. degree in 1950. He stayed at Chicago to earn an M.S. degree in mathematics in 1951, then went to Princeton University, where he obtained a Ph.D. degree in 1954.[1] His thesis, titled "The relative cohomology structure of formations", was written under the direction of Emil Artin.[2]
After first teaching mathematics at Dartmouth College and the University of Wisconsin–Madison, he joined the Stanford University faculty[3] in 1957, becoming a full professor in 1966. During sabbaticals and leaves he also spent time at the Institute for Advanced Study and at Churchill College, Cambridge (where he was a Fulbright Fellow). He was also a Member-at-Large of the Council of the American Mathematical Society.[1]
Death and legacy
editDeLeeuw was murdered by Theodore Streleski, a Stanford doctoral student for 19 years, whom he advised.[4] DeLeeuw's widow Sita deLeeuw was critical of media coverage of the crime, saying, "The media, in their eagerness to give Streleski a forum, become themselves accomplices in the murder—giving Streleski what he wanted in the first place."[5]
A memorial lecture series was established in 1978 by the Stanford Department of Mathematics to honor deLeeuw's memory.[6][7]
