Moncure Daniel Conway (March 17, 1832 November 15, 1907) was an American abolitionist as well as at various times a Methodist, Unitarian and Freethought minister. The radical writer descended from patriotic and patrician families of Virginia and Maryland spent most of the final four decades of his life abroad in England and France, where he wrote biographies of Edmund Randolph, Nathaniel Hawthorne and Thomas Paine, as well as his own autobiography, and led freethinkers in London's South Place Chapel.
