Joan Sylvia Lyttle Birman (born May 30, 1927 in New York City) is an American mathematician, specialising in low-dimensional topology. She has given contributions to the study of knots, 3-manifolds, mapping class groups of surfaces, geometric group theory, contact structures and dynamical systems. Birman is currently Research Professor Emerita at Barnard College, Columbia University, where she has been since 1973.
Her parents were George and Lillian Lyttle, both Jewish immigrants. Her father was from Russia but grew up in Liverpool, England. Her mother was born in New York and her parents were Russian-Polish immigrants. At age 17, George emigrated to the US and became a successful dress manufacturer. He appreciated the opportunities from having a business but he wanted his daughters to focus on education. She has three children. Her late husband, Joseph Birman, was a physicist and a leading advocate for human rights for scientists.
After high school, Birman entered Swarthmore College, a coeducational institution in Swarthmore, Pennsylvania, and majored in mathematics. However, she disliked living in the dorms so she transferred to Barnard College, a women's only college affiliated to Columbia University, to live at home.
Birman received her B.A. (1948) in mathematics from Barnard College and an M.A. (1950) in physics from Columbia University. After working in the industry from 1950 to 1960, she did a PhD in mathematics at the Courant Institute (NYU) under the supervision of Wilhelm Magnus, graduating in 1968. Her dissertation was titled Braid groups and their relationship to mapping class groups.
Birman's first position was at the Stevens Institute of Technology (1968–1973). She also was a visiting professor at Princeton University during part of this period. In 1973, she joined the faculty at Barnard College. In 1987 she was selected by the Association for Women in Mathematics to be a Noether Lecturer; this lecture honors women who have made fundamental and sustained contributions to the mathematical sciences. She was a visiting scholar at the Institute for Advanced Study in the summer of 1988. She has also been a Sloan Foundation Fellow (1974–76) and a Guggenheim Foundation Fellow (1994–95). In 1996, she won the Chauvenet Prize. Then in 2005, she won the New York City Mayor's Award for Excellence in Science and Technology.
In 2012, she became a fellow of the American Mathematical Society. She supervised 21 doctoral students, and has a total of 50 academic descendants. Her doctoral students include Józef Przytycki.
In 2017, she endowed the Joan and Joseph Birman Fellowship for Women Scholars at the American Mathematical Society to support mathematical research by mid-career women.
Birman's scientific work includes 77 research publications and 16 expository articles or reviews. She is the author of the research monograph Braids, Links, and Mapping Class Groups.
