Louis Marshall (December 14, 1856 – September 11, 1929) was an American corporate, constitutional and civil rights lawyer, mediator and Jewish community leader who worked to secure religious, political, and cultural freedom for all minority groups. He was among the founders of the American Jewish Committee (AJC), defended Jewish and minority rights and, though not a Zionist, he supported the Balfour Declaration. He was also a conservationist, and was instrumental in (re)establishing the New York State College of Forestry at Syracuse University, which has evolved into today's State University of New York College of Environmental Science and Forestry (SUNY-ESF).
