FORSTER, FRIEDRICH WILHELM ), Ger man psychologist and educationalist, was born in Berlin on June 2, 1869, and educated in Berlin and Freiburg. After some years spent in the study and practice of education, especially among poverty-stricken or criminal classes, he began to teach at Zurich university, and to issue a series of books, which achieved immense popularity and influence, advocating education in the spirit of a positive Catholic Christianity, with reference to practical prob lems. The chief of these works were Jugendlehre (1904), Lebens kunde (1904), Schule and Cstarakter (19o7), Sexualethik .und Sexualpadagogik (1918) , Jugendseele, Jugendbewegung, Jugend ziel (1923) . In 1912 Forster resigned his post in Zurich, taking up work at Munich university in 1913. He had already published various political works, and during the World War became promi nent as a pacifist. His political works include Weltpolitik and Weltgewissen (1919) and Mein Kam p f gegen das militdristische and nationalistische Deutschland (1920). In 1920 he was forced, on account of his views, to resign his Munich post, and returned to Zurich, where he was employed as Bavarian Minister in Switzer land. He continued, however, to issue in rapid succession works which lost little of their popularity.
