For forty years between 1932 and 1972, the U.S. Public Health Service (PHS) conducted an experiment on 399 black men in the late stages of syphilis.....
As a doctor explained, If the colored population becomes aware that accepting free hospital care means a post-mortem, every darky will leave Macon County
Even the Surgeon General of the United States participated in enticing the men to remain in the experiment, sending them certificates of appreciation after 25 years in the study.....
One of the most chilling aspects of the experiment was how zealously the PHS kept these men from receiving treatment.

Pleased at their success, the PHS representative announced: So far, we are keeping the known positive patients from getting treatment. The experiment continued in spite of the Henderson Act (1943), a public health law requiring testing and treatment for venereal disease
