Shelby worked as a European correspondent for
CBS Radio in Geneva. In 1941, he became a member of the
New York Stock Exchange. Six years later, with an investment of $100,000, he founded and headed Shelby Cullom Davis & Company, an investment firm, specializing in insurance securities. Shelby joined the staff of
District Attorney Thomas E. Dewey as an economist and research assistant. He advised Dewey during his presidential runs in
1940 and
1944 and was later appointed by then-
New York Governor Dewey as First Deputy Superintendent of Insurance from 1944 to 1947.
Philanthropy He provided significant financial support to
Princeton University, funded chairs and professorships at
Wellesley College, and endowed the Cullom - Davis Library at
Bradley University. A Professorship of International Security Studies at
Fletcher School of Law and Diplomacy was also instituted in his name. He also provided support to the Library and Museum of the Performing Arts at
Lincoln Center in NYC. His generous support of the
Society of Colonial Wars is recognized in part through the Shelby Cullom Davis Lecture. In December 2013 it was announced that through his charitable fund a $10 million donation was made to
Colby College, Waterville, Maine. The Shelby Cullom Davis Center for Historical Studies in the
Department of History at
Princeton University is named after Davis. The use of funds meant to endow the Shelby Cullom professorship at
Trinity College in
Hartford, Connecticut led in part to the resignation of that college's president
James Jones, as well as media attention to the donor intent issue. ==Affiliations==
