Oh, I remember reading about this here

"When the study ended, it had been forty years since the doctors administered their first placebo treatment for "bad blood" in Tuskegee. Over the course of the study, twenty-eight of the men had died of syphilis, and one hundred were dead due to related complications. Many of these patients died after penicillin had become readily available. Of the 399 original infected volunteers, only seventy-four survived to learn that their doctors had only been pretending to treat their disease for the past four decades. In addition, it was found that forty of the mens' wives had been infected during the study, and nineteen of their children had been born with congenital syphilis."
I can't really say anything... just... awful.
