Dr William Leonard Ferrar FRSE (21 October 1893 – 22 January 1990) was an English mathematician. He focused on interpolation theory and number theory.
Early life
Ferrar was born on 21 October 1893 in St Pauls, Bristol, the son of Maria Susannah Ferrar and her husband George William Persons Ferrar, a lamplighter.{{cite book|title=Biographical Index of Former Fellows of the Royal Society of Edinburgh 1783–2002|date=July 2006|publisher=The Royal Society of Edinburgh|isbn=0-902-198-84-X|url=https://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp1.pdf|access-date=5 May 2016|archive-date=24 January 2013|archive-url=https://web.archive.org/web/20130124115814/http://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp1.pdf|url-status=dead}}
He attended Bristol Grammar School. In 1912, he gained a place at The Queen's College in Oxford, winning the Junior Mathematical Scholarship in 1914.{{cite web|title=William Leonard Ferrar Biography|url=http://www-history.mcs.st-andrews.ac.uk/Biographies/Ferrar.html|website=www-history.mcs.st-andrews.ac.uk|publisher=School of Mathematics and Statistics University of St Andrews, Scotland|accessdate=2 July 2015}} His studies were interrupted by the First World War during which he first spent as a telephonist in the artillery then as an intelligence officer in France.
He returned to Oxford in 1919 and graduated MA in 1920, and later received a doctorate (DSc).
Career
He spent his first 4 years working in Bangor then was invited to the University of Edinburgh by Edmund Whittaker as a lecturer in mathematics. There he worked with Edward Copson and Alec Aitken,{{Cite web|url=http://www-groups.dcs.st-and.ac.uk/history/Biographies/Ferrar.html|title=Bill Ferrar - Biography}} and wrote papers on convergent series, interpolation theory, and number theory.
In 1925, he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Edmund Whittaker, Edward Copson, Sir Charles Galton Darwin and David Gibb.{{cite book|title=Biographical Index of Former Fellows of the Royal Society of Edinburgh 1783–2002|date=July 2006|publisher=The Royal Society of Edinburgh|isbn=0-902-198-84-X|url=https://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp1.pdf|access-date=5 May 2016|archive-date=24 January 2013|archive-url=https://web.archive.org/web/20130124115814/http://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp1.pdf|url-status=dead}}
In the autumn of 1925, he took up a new role at the University of Oxford.
From its creation until 1933, he was the editor at the University of the Quarterly Journal of Mathematics in which he published many papers. In 1937, he became the bursar of Hertford College, Oxford which he was employed at for 22 years. After being the bursar in 1959, he became the Principal of the college. In 1947, he belated applied for a doctorate and received a DSc.
