The University of Pennsylvania Law School traces its origins to a series of "Lectures on Law" delivered in 1790 through 1792 by James Wilson, one of only six signers of the United States Declaration of Independence and the United States Constitution. Wilson is credited with being one of the two primary authors (the other being James Madison) of the first draft of such constitution due to his membership on the Committee of Detail established by the United States Constitutional Convention on July 24, 1787 to draft a text reflecting the agreements made by the Convention up to that point.
