American mathematician, editor, and author; born in Eger, Hungary, Jan. 18, 1853; son of Morris Joshua and Sarah Heilprin, of a family which has had several distinguished representatives in the United States. He was graduated B.A. from Columbian University, Washington, D. C., in 1869, and engaged in civil engineering and surveying up to 1877. In that year he became, by invitation, a fellow of Johns Hopkins University (Ph.D. 1880), where he exhibited unusual ability in mathematics, being successively appointed assistant, associate, associate professor, and professor of mathematics in that university (1879-95). Franklin has always been greatly interested in economic and public questions, and in 1895 he retired from his professorship and assumed editorial charge of the "Baltimore News." He has contributed to the "American Journal of Mathematics" and other mathematical publications, to the "Nation," and to the "North American Review." Franklin is an associate fellow of the American Academy of Arts and Sciences, Boston.
