Tuskegee Syphilis Study
The Tuskegee Study of Untreated Syphilis in the Negro Male (informally referred to as the Tuskegee Experiment or Tuskegee Syphilis Study) was a study conducted between 1932 and 1972 by the United States Public Health Service (PHS) and the Centers for Disease Control and Prevention (CDC) on a group of nearly 400 African American men with syphilis as well as a control group without. The purpose of the study was to observe the effects of the disease when untreated, to the point of death and autopsy.
