Professor Kessler-Harris specializes in the history of American labor and 20th-century social policy. Her books include In Pursuit of Equity: Women, Men and the Quest for Economic Citizenship in Twentieth Century America (2001), which won the Bancroft, Taft, Joan Kelly, and Herbert Hoover prizes; Gendering Labor History (2007), which contains her essays on women, work and social policy, the recently re-issued A Woman’s Wage: Historical Meanings and Social Consequences (1990), and A Difficult Woman: The Challenging Life and Times of Lillian Hellman (2012).
