Reva B. Siegel (born 1956) is the Nicholas deB. Katzenbach Professor of Law at Yale Law School. Siegel's writing draws on legal history to explore questions of law and inequality, and to analyze how courts interact with representative government and popular movements in interpreting the Constitution. She is currently writing on the role of social movement conflict in guiding constitutional change, addressing this question in recent articles on reproductive rights, originalism and the Second Amendment, the "de facto ERA," and the enforcement of Brown. Her publications include Processes of Constitutional Decisionmaking (with Brest, Levinson, Balkin & Amar, 2014); The Constitution in 2020 (edited with Jack Balkin, 2009); and Directions in Sexual Harassment Law (edited with Catharine A. MacKinnon, 2004). Professor Siegel received her B.A., M.Phil, and J.D. from Yale University, clerked for Judge Spottswood Robinson on the D.C. Circuit, and began teaching at the University of California at Berkeley. She is a member of the American Academy of Arts and Sciences, and is active in the American Society for Legal History, the Association of American Law Schools, the American Constitution Society, in the national organization and as faculty advisor of Yale's chapter. She was elected to the American Philosophical Society in 2018.
