Philip Jourdain

Philip Edward Bertrand Jourdain (1879–1919), Cambridge-educated logician and historian of mathematics and logic. As a student at Cambridge he took BR’s course on mathematical logic in 1901–02 and subsequently wrote many articles on mathematical logic, set theory, and the foundations of mathematics, among a number of other topics. His extraordinary productivity was achieved despite the ravages of Friedreich’s ataxia, a form of progressive paralysis that killed him in 1919. His extensive correspondence with BR was published (with commentary) in I. Grattan-Guinness, Dear Russell — Dear Jourdain (London: Duckworth, 1977).
