The Tuskegee Experiment was on 399 niggers in the late stages of syphilis. These niggers were never told what disease they were suffering from, and their doctors had no intention of curing them of syphilis at all. The data for the experiment was to be collected from autopsies of the niggers, and they were thus deliberately left to degenerate. “We have no further interest in these niggers until they die", said one of the doctors.
