Louis T. Wright - Wikipedia

Louis Tompkins Wright, MD, FACS[1] (July 23, 1891 – October 8, 1952)[2] was an American surgeon and civil rights activist. In his position at Harlem Hospital he was the first African-American on the surgical staff of a non-segregated hospital in New York City. He was influential for his medical research as well as his efforts pushing for racial equality in medicine and involvement with the National Association for the Advancement of Colored People (NAACP), which he served as chairman for nearly two decades.[3][4]

Shortly after completing medical school and moving back to Georgia, Wright joined the Army Medical Corps, serving as a lieutenant during World War I, stationed in France. While there he introduced intradermal vaccination for smallpox and was awarded the Purple Heart after a gas attack.[2][4]
