Dr. Mary Susan Moore was born 1865 in Chatham County, North Carolina. She earned her Doctorate of Medicine in 1898 from Meharry Medical Department of Central Tennessee College (now Meharry Medical College). Dr. Moore was the first Black female physician to practice medicine in Texas. In 1903, she and her husband, Dr. James D. Moore, opened a forty-bed hospital, Hubbard Sanitarium, in Galveston to serve the health needs of Black people. For four years Dr. Moore and her husband fought opposition from residents and local government. In 1907, the city of Galveston repealed the ordinance prohibiting the operation of Hubbard Sanitarium. Dr. Moore and her husband maintained the hospital until about 1925. Dr. Mary Susan Moore died August 22, 1965.
