Mary Brown Wanamaker Warburton (1869 – November 18, 1954) was an American social and political leader. She was the first woman to head the Pennsylvania Republican Committee.[1] She was a daughter of U.S. Postmaster General John Wanamaker and wife of publisher Barclay Harding Warburton I.[2]
Wanamaker was noted for her civil rights activity and southern newspapers wrote scandalously about her when, in 1905, Booker T. Washington was invited to dine with her family at a hotel and he escorted her to the table, arm-in-arm.[3]
