From 1932 to 1972, the U.S. Public Health Service conducted an experiment involving more than 400 black male sharecroppers infected with syphilis. The men weren't told they had syphilis; they weren't warned of its effects; and they were given no medication stronger than aspirin. The first edition of this book explained how this tragedy happened. Now, a new introduction and concluding chapter reveal its bitter legacy in the age of AIDS. 16 pages of photos.
