He was born in Ashbourne in Derbyshire one of a large family belonging to Emily Clay and his father Francis Jourdain (who was the vicar at Ashbourne). He was partly disabled by Friedreich's ataxia. He corresponded with Georg Cantor and Gottlob Frege, and took a close interest in the paradoxes related to Russell's paradox, formulating the card paradox version of the liar paradox. He corresponded with Ludwig Wittgenstein, meeting with him in Cambridge to discuss Frege's book Grundgesetze der Arithmetik, parts of which Jourdain had prepared a translation. He also worked on algebraic logic, and the history of science with Isaac Newton as a particular study. He was London editor for The Monist. Near the end of his life he became increasingly obsessed by trying to prove the axiom of choice, and published several incorrect proofs of it. Littlewood (1986, p.129) describes Jourdain on his deathbed still arguing with him about his (incorrect) proof of the axiom of choice.
His sister Eleanor Jourdain was an English academic and author. Another sister, Margaret (1876–1951), was an authority on the history of fine English home-furnishings, and the life-long companion of the novelist Ivy Compton-Burnett.
