with a BA with first-class honours. After graduating from Oxford, Ayer spent a year in Vienna, returned to England and published his first book, Language, Truth and Logic, in 1936. The first exposition in English of logical positivism as newly developed by the Vienna Circle, this made Ayer at age 26 the enfant terrible of British philosophy. As a newly famous intellectual, he played a prominent role in the Oxford by-election campaign of 1938. Ayer campaigned first for the Labour candidate Patrick Gordon Walker, and then for the joint Labour-Liberal "Independent Progressive" candidate Sandie Lindsay, who ran on an anti-appeasement platform against the Conservative candidate, Quintin Hogg, who ran as the appeasement candidate. The by-election, held on 27 October 1938, was quite close, with Hogg winning narrowly. In the Second World War, Ayer served as an officer in the Welsh Guards, chiefly in intelligence (Special Operations Executive (SOE) and MI6). He was commissioned second lieutenant into the Welsh Guards from Officer Cadet Training Unit on 21 September 1940. After the war, Ayer briefly returned to the University of Oxford where he became a fellow and Dean of Wadham College. He then taught philosophy at London University from 1946 until 1959, when he also started to appear on radio and television. He was an extrovert and social mixer who liked dancing and attending clubs in London and New York. He was also obsessed with sport: he had played rugby for Eton, and was a noted cricketer and a keen supporter of Tottenham Hotspur football team, where he was for many years a season ticket holder. For an academic, Ayer was an unusually well-connected figure in his time, with close links to 'high society' and the establishment. Presiding over Oxford high-tables, he is often described as charming, but could also be intimidating. Ayer was married four times to three women. His first marriage was from 1932 to 1941, to (Grace Isabel) Renée, with whom he had a son—allegedly in fact the son of Ayer's friend and colleague Stuart Hampshire—and a daughter. Renée subsequently married Hampshire. In 1960, Ayer married Alberta Constance (Dee) Wells, with whom he had one son. That marriage was dissolved in 1983, and the same year, Ayer married Vanessa Salmon, the former wife of politician Nigel Lawson. She died in 1985, and in 1989 Ayer remarried Wells, who survived him. He also had a daughter with Hollywood columnist Sheilah
