The People's Hospital was constructed in 1909 by a benevolent society, the Saint Louis Provident Association, which was one of the earliest such groups dedicated to social work.
The building was converted into a hospital after the People's Hospital group purchased it in 1944. They opened their doors on October 10th and here they operated a 75 room short term non-profit hospital serving primarily African Americans. The People's Hospital also ran a nursing school at this location, one of the only post-secondary education opportunities for minority women in the area.
The People's Hospital closed in 1967. It would house a home for the blind until 1972, but since then it has been mostly vacant.
