Mary Sarah Bilder teaches at Boston College Law School in the areas of property, trusts and estates, and American legal and constitutional history. In 2016, she was named the Founders Professor of Law. Her recent scholarship focuses on the early history of the Constitution: the concept of a Framing Generation; Native Nations and the 1787 Constitution; the early constitutional status of women; written constitutionalism as a new genre; James Madison's Notes of the Convention; the history of judicial review; and colonial and founding era constitutionalism.
Bilder is the author of three books. The first, Madison's Hand: Revising the Constitutional Convention (Harvard University Press), was awarded the 2016 Bancroft Prize in American History and Diplomacy and the James C. Bradford Prize for Biography from the Society for Historians of the Early Republic. It was also named a finalist for the George Washington Book Prize. The second, The Transatlantic Constitution: Colonial Legal Culture and the Empire (Harvard University Press), received the Littleton-Griswold Award from the American Historical Association. Her most recent book, Female Genius: Eliza Harriot and George Washington at the Dawn of the Constitution (University of Virginia Press), is based on the life and constitutional influence of Elizabeth Harriot Barons O'Connor, a female lecturer and educator in Philadelphia in the summer of 1787.
She has published numerous articles in the Yale Law Journal, Stanford Law Review, Yale Journal of Law and the Humanities, George Washington Law Review, Law and History Review, Law Library Journal, and Journal of Policy History. Recently, she co-authored an article on the library of Robert Morris, an important African American lawyer and civil rights activist. Her most recent essay on the founding period appears in With Liberty and Justice for All? The Constitution in the Classroom (2022), designed for secondary and college level American history courses. She is currently working on a larger project, The Framing Generation: The People, the Constitution, and Washington and a smaller project about Catharine Macaulay and the challenges facing the female constitutional historian.
