Frank Bonsall

Bonsall was born on 31 March 1920, the youngest son of Wilfred C Bonsall and Sarah Frank. His older brother was Arthur Bonsall.[2] He married Gillian Patrick, in 1947.[3] Bonsall and his wife were keen hill-walkers.[4] 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.

Bonsall graduated from Bishop's Stortford College in 1938, and studied at Merton College, Oxford.[3] He served in World War II, in the Corps of Royal Engineers, and in India from 1944 to 1946.[5]

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.[6] 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.[7] 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".
