To commemorate the signing of the U.S. Constitution, Harvard Law School Professor Michael Klarman, an expert on constitutional law and constitutional history, gave a lecture at Harvard Law School on Tuesday, Sept. 17. His talk, titled “Not Written in Stone,” focused on the reasons he believes the U.S. Constitution should not be given undue reverence.

The event, sponsored by the HLS American Constitution Society, was held to mark Constitution Day—an annual, national celebration of the signing of the U.S. Constitution on Sept. 17, 1787.

Klarman is the author of many books, including: “From the Closet to the Altar: Courts, Backlash, and the Struggle for Same-Sex Marriage” (Oxford University Press, October 2012); “Brown v. Board and the Civil Rights Movement “(Oxford University Press 2007); “Unfinished Business: Racial Equality in American History” (Oxford University Press 2007); and “From Jim Crow to Civil Rights: The Supreme Court and the Struggle for Racial Equality” (Oxford University Press 2004).
