David Bernard Alper Epstein FRS (born 1937) is a mathematician known for his work in hyperbolic geometry, 3-manifolds, and group theory, amongst other fields. He co-founded the University of Warwick mathematics department with Christopher Zeeman and is founding editor of the journal Experimental Mathematics.
Higher education and early career
In 1954, Epstein came to the UK after completing his bachelor's degree in mathematics in South Africa. Having received the exemption for Mathematical Tripos part I at the University of Cambridge, he completed Mathematical Tripos part II in 1955 and Mathematical Tripos part III in 1957. He completed his Ph.D. on the topic of three-dimensional manifolds under the supervision of Christopher Zeeman in 1960. He then travelled to Princeton University, where he spent one year attending the lectures of Norman Steenrod on cohomology operations, making notes and revisions to them, later published as a book by the Princeton University Press in 1962
