"From 1932 to 1972 the US government carried out the Tuskegee Study, a clinical study of syphilis on 400 poor, African-American citizens. The government promised free treatment, but instead the subjects were given false and dangerous treatments, such as aspirin, while adequate treatment was intentionally withheld so the progress of the disease could be observed. 128 subjects died from syphilis or related complications, so their autopsies also became relevant to the study. In addition 40 women contracted syphilis from male subjects who were denied knowledge of their condition, and 19 children were born with congenital disease."
