Thirty years ago today, the Washington Evening Star newspaper ran this headline on its front page: "Syphilis Patients Died Untreated." With those words, one of America's most notorious medical studies, the Tuskegee Syphilis Study, became public. "For 40 years, the U.S. Public Health Service has conducted a study in which human guinea pigs, not given proper treatment, have died of syphilis and its side effects," Associated Press reporter Jean Heller wrote on July 25, 1972. "The study was conducted to determine from autopsies what the disease does to the human body."
