Joseph Alvin Neisendorfer (born April 22, 1945 in Chicago) is an American mathematician known for his work in homotopy theory, an area of algebraic topology. [1] He is a Fellow of the American Mathematical Society. [2]
Neisendorfer earned his bachelor's degree in 1967 from the University of Chicago. He earned his master's degree in 1968 and his doctorate in 1972 from Princeton University, working under the direction of John Coleman Moore. [3] [4]
In 1972 he began working as an assistant professor at the University of Notre Dame, then in 1976 at Syracuse University, and then in 1978 at Fordham University. In 1980–1981 he worked at the Institute for Advanced Study after which he became an associate professor at Ohio State University. He served as a professor at the University of Rochester from 1985 until his retirement in 2011, serving as department chair from 1994 to 1996.
During his tenure as the department chair, the University of Rochester experienced severe financial challenges which led to significant restructuring entitled the Rochester Renaissance Plan. [5] In November 1995, the mathematics department was told by the University of Rochester administration that the doctoral program was slated for removal and that the departmental faculty slated for significant downsizing, and admissions to the University of Rochester doctoral program in Mathematics were suspended. [6] This decision led to the involvement of the American Mathematical Society, who passed a resolution urging Rochester to reconsider and formed a task force (chaired by Arthur Jaffe) to address the issue. [7] After a fact-finding committee organized by Neisendorfer sent their report to the university administration, the doctoral program in mathematics was restored. [8] [9] [10]

Milnor is a distinguished professor at Stony Brook University and one of the five mathematicians to have won the Fields Medal, the Wolf Prize, and the Abel Prize
Vladimir Alexandrovich Voevodsky was a Russian-American mathematician. His work in developing a homotopy theory for algebraic varieties and formulating motivic cohomology led to the award of a Fields Medal in 2002. He is also known for the proof of the Milnor conjecture and motivic Bloch–Kato conjectures and for the univalent foundations of mathematics and homotopy type theory.
John Henry Constantine Whitehead FRS, known as Henry, was a British mathematician and was one of the founders of homotopy theory. He was born in Chennai, in India, and died in Princeton, New Jersey, in 1960.

Phillip Augustus Griffiths IV is an American mathematician, known for his work in the field of geometry, and in particular for the complex manifold approach to algebraic geometry. He was a major developer in particular of the theory of variation of Hodge structure in Hodge theory and moduli theory. He also worked on partial differential equations, coauthored with Shiing-Shen Chern, Robert Bryant and Robert Gardner on Exterior Differential Systems.
David Gabai is an American mathematician and the Hughes-Rogers Professor of Mathematics at Princeton University. Focused on low-dimensional topology and hyperbolic geometry, he is a leading researcher in those subjects.
