# W. B. R. Lickorish

**William Bernard Raymond Lickorish** (born 19 February 1938) is a mathematician. He is emeritus professor of geometric topology in the , University of Cambridge, and also an emeritus fellow of Pembroke College, Cambridge. His research interests include topology and knot theory. He was one of the discoverers of the HOMFLY polynomial invariant of links, and proved the Lickorish-Wallace theorem which states that all closed orientable 3-manifolds can be obtained by Dehn surgery on a link.

Lickorish received his Ph.D from Cambridge in 1964; his thesis was written under the supervision of Christopher Zeeman.^{[1]}

In 1991, Lickorish received the Senior Whitehead Prize from the London Mathematical Society.^{[2]}
He was included in the 2019 class of fellows of the American Mathematical Society "for contributions to knot theory and low-dimensional topology".^{[3]}
