Prison Inmates as Test Subjects

in 1951, Dr. Albert M. Kligman, a dermatologist at the University of Pennsylvania and future inventor of Retin-A, began experimenting on inmates at Philadelphia’s Holmesburg Prison. As Kligman later told a newspaper reporter, “All I saw before me were acres of skin. It was like a farmer seeing a field for the first time.” Over the next 20 years, inmates willingly allowed Kligman to use their bodies in experiments involving toothpaste, deodorant, shampoo, skin creams, detergents, liquid diets, eye drops, foot powders, and hair dyes. Though the tests required constant biopsies and painful procedures, none of the inmates experienced long-term harm.
