Philippe Devaux (1902 – 1979) was a French-speaking Belgian philosopher and logician, professor at the University of Liège. Through his numerous works and translations (he was the translator and friend of Russell), he played a great part in the development of analytic philosophy in French-speaking countries.
After a first study devoted to the philosophy of Samuel Alexander in 1929, Philippe Devaux was appointed as a FNRS research associate in Belgium, and then for two year as an advanced fellow at the Berkeley and Harvard Universities, where he studied with Alfred North Whitehead. After becoming professor at the University of Liège, he also taught at the universities of Brussels, Manchester, Hull and London. Paul Gochet was his student and assistant in Liège.
