The experiment's name comes from the Tuskegee Institute, the black university founded by Booker T. Washington. Its affiliated hospital lent the PHS its medical facilities for the study, and other predominantly black institutions as well as local black doctors also participated.
Tuskegee Institute in Alabama opened in 1881, and it was one of most famous training schools. Booker T. Washington was its president. Job skills such as carpentry, printing, brick making, and home economics were taught there. Tuskegee also provided training for elementary school teachers.
