Czech anthropologist, philosopher and sociologist (1925–1995)
Ernest André Gellner (9 December 1925 – 5 November 1995) was a British-Czech philosopher and social anthropologist described by The Daily Telegraph, when he died, as one of the world's most vigorous intellectuals, and by The Independent as a "one-man crusader for critical rationalism". His first book, Words and Things (1959), prompted a leader in The Times and a month-long correspondence on its letters page over his attack on linguistic philosophy.
