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.
He earned his master's degree in 1968 and his doctorate in 1972 from Princeton University, working under the direction of John Coleman Moore.
[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.
