The committee proceeded to set up a series of boards, or bureaus: Education (1910), Social Morals (1912); Industry (1914); and Philanthropic Research (1916). The first secretary of the Bureau of Education was Henrietta Szold. A report by Rabbi Mordecai Kaplan revealed that of some 200,000 Jewish children of school age no more than 50,000 received any form of Jewish education. By 1916 the Bureau directed or supervised 200 schools, 600 teachers and 35,000 pupils. Funding was dependent on wealthy New York Jews such as Jacob Schiff, Felix Warburg and Louis Marshall who made an endowment for girls' education. The Bureau eventually evolved into the Jewish Education Committee of New York. Magnes was also closely involved with the Social Morals Bureau which held investigations into the white-slave-traffic and the Jewish underworld. Its work is held responsible of reducing Jewish juvenile delinquency from 30% of the New York total to 14% twenty years later. In the Bureau of Industry he was Chairman of the Conference of the Furriers Trade.
