Auguste Marie François Beernaert (July 26, 1829-October 6, 1912) was born in Ostend, Belgium, in a middle-class Catholic family of Flemish origin.
Beernaert was prime minister of Belgium and finance minister for the next ten years.
One of Belgium's leading pacifists, Beernaert became an active member of the Interparliamentary Union after he resigned from the prime ministry, presided over several of its conferences, and served as president of its Council after 1899 and of its Executive Committee after its creation in 1908.
