Trevor Henry Aston (14 June 1925 – 17 October 1985) was a British historian and academic at the University of Oxford.
After two terms at St John's College, Oxford, studying Philosophy, Politics and Economics, Aston joined the Royal Marines in 1943 but did not see combat.
Back in Oxford in 1946, he switched to read Modern History and obtained a first-class degree in 1949.
His behaviour, at times very difficult for colleagues to bear, led to problematic relations within the college and to a separation from his wife.
[1] The then president of the college, Sir Kenneth Dover, admitted in his memoirs that he had been exasperated with the effects of Aston's illness and, having exhausted all other tactics, he knowingly pushed Aston into a pressured situation which might precipitate suicide.
