Passy, Frédéric (frādārēkˈ päsēˈ) [key], 1822–1912, French economist, winner (1901, with J. H. Dunant) of the first Nobel Peace Prize. He studied law but abandoned it for journalism and the study of economics and problems of peace. In 1867 he founded the International League for Permanent Peace, later known as the French Society of the Friends of Peace; he served as its general secretary until 1889, when, in association with Sir William R. Cremer, he founded the Inter-Parliamentary Union of Arbitration. He was a member of the chamber of deputies from 1874 to 1889. His best-known work is Historique du mouvement de la paix (1904). The phonetician Paul Edouard Passy (1859–1940) was his son.
