Richard M. Pollack (January 25, 1935 – September 18, 2018[2][3]) was an American geometer who spent most of his career at the Courant Institute of Mathematical Sciences at New York University, where he was Professor Emeritus until his death.

[8][9][10][11][12][13][14][15][16][17][18] His work with Jacob E. Goodman includes the first nontrivial bounds on the number of order types and polytopes,[8] and a generalization of the Hadwiger transversal theorem to higher dimensions.

[19] In real algebraic geometry, Pollack wrote a series of papers with Saugata Basu and Marie-Françoise Roy,[13][14][15][16] as well as a book.

[20] In 2003, a collection of original research papers in discrete and computational geometry entitled Discrete and Computational Geometry: The Goodman–Pollack Festschrift was published as a tribute to Jacob E. Goodman and Richard Pollack on the occasion of their 2/3 × 100 birthdays.

[22] A special memorial 556-page issue of Discrete & Computational Geometry for Pollack was published in October 2020.
