Bad Blood. By J. H. Jones

...The Tuskegee Study of Untreated Syphilis in the Negro Male, a 40-year deathwatch over the lives of more than 400 black sharecroppers in Macon County, Ala. [was a nightmare]. ...There, from 1932 to 1972, the United States Public Health Service conducted a "study," which was actually, as historian James H. Jones shows, an ugly collaboration involving Public Health Service physicians, local private practitioners (white and black), the prestigious all-black Tuskegee Institute and Hospital, the county and state health departments, even draft boards.
