The first comprehensive history of medical experimentation on African Americans. Starting with the earliest encounters between Africans and Western medical researchers and the racist pseudoscience that resulted, it details the way both slaves and freedmen were used in hospitals for experiments conducted without a hint of informed consent--a tradition that continues today within some black populations. It shows how the pseudoscience of eugenics and social Darwinism was used to justify experimental exploitation and shoddy medical treatment of blacks, and a view that they were biologically inferior, oversexed, and unfit for adult responsibilities. New details about the government's Tuskegee experiment are revealed, as are similar, less well-known medical atrocities conducted by the government, the armed forces, and private institutions. This book reveals the hidden underbelly of scientific research and makes possible, for the first time, an understanding of the roots of the African American health deficit.
