Frank Bonsall
Frank Featherstone Bonsall FRS[1] (31 March 1920, Crouch End, London – 22 February 2011,[2] Harrogate) was a British mathematician.[3]
Personal life
Bonsall was born on 31 March 1920, the youngest son of Wilfred C Bonsall and Sarah Frank. His older brother was Arthur Bonsall.[4] He married Gillian Patrick, a Somerville graduate, in 1947.[5] Bonsall and his wife were keen hill-walkers.[1] He wrote two articles for The Scottish Mountaineering Club on the definition of a Munro. After his retirement, Bonsall and his wife moved to Harrogate.
Career
Bonsall graduated from Bishop's Stortford College in 1938, and studied at Merton College, Oxford.[5] He served in World War II, in the Corps of Royal Engineers, and in India from 1944 to 1946.[6]
He lectured at the University of Edinburgh from 1947 to 1948; was visiting associate professor at Oklahoma State University from 1950 to 1951; taught at Newcastle University, with Werner Wolfgang Rogosinski in the 1950s. He taught at the University of Edinburgh, from 1963 to 1984.[7] In 1963, a second chair in Mathematics was established (the Maclaurin chair). Bonsall took up the chair in 1965, but spent the following year as a visiting professor at Yale.[4] In 1966, he was awarded the London Mathematical Society's Berwick Prize.
Despite not himself having a PhD, Bonsall supervised many PhD candidates[8] who knew him affectionately as "FFB".
