Lawrence Gene Sager (born 1941) is a former dean of the The University of Texas School of Law at The University of Texas at Austin. He holds the Alice Jane Drysdale Sheffield Regents Chair and is one of the nation's preeminent constitutional theorists and scholar. Sager, who joined the Law School faculty in 2002, is the 13th dean in the Law School's 123-year history. He is best known for his theory of underenforcement.
A graduate of Columbia Law School and Pomona College, Sager taught for more than 25 years at New York University School of Law, where he was instrumental in transforming the NYU faculty into one of the best in the nation. At Texas, he has also been deeply involved with the Law School's successful faculty recruitment efforts, which include luring corporate law expert Bernard Black from Stanford Law School in 2004 and health law scholar William Sage from Columbia Law School in 2006. He served as chair of the Law School's Appointments Committee during the 2005–06 academic year. Sager has also taught as a visiting professor at Harvard Law School, Princeton University, Boston University School of Law, UCLA School of Law, and University of Michigan Law School.
Sager is the author or co-author of dozens of articles as well as two books: Justice in Plainclothes: A Theory of American Constitutional Practice (Yale University Press, 2004) and, with Christopher Eisgruber, Religious Freedom and the Constitution, (Harvard University Press, 2007).
Sager rose to prominence as a legal scholar while teaching at the New York University (NYU) School of Law. Along with NYU’s John Sexton, Sager has been credited as one of the chief architects of New York University Law School’s precipitous rise in the national rankings during the 1990s. Sager joined the University of Texas at Austin (UT) School of Law faculty in 2002 and was appointed dean in 2006.
