Eleanor Harriet Bernert Sheldon (March 19, 1920 – May 8, 2021) was an American sociologist who was president of the Social Science Research Council (SSRC) from 1972 to 1979, and was one of the key pioneers in the use of social indicators in sociology. In the 1970s, as multinational corporations recognized the need to appoint women to their boards of directors, Sheldon became the first woman to serve on the boards of several major companies, including Citibank, Mobil, Heinz, and Equitable Holdings.
