Philadelphia apologizes for experiments on Black inmates

The city of Philadelphia issued an apology Thursday for the unethical medical experiments performed on mostly Black inmates at its Holmesburg Prison from the 1950s through the 1970s.

The move comes after community activists and families of some of the inmates raised the need for a formal apology. It also follows a string of apologies from various U.S. cities over historically racist policies or wrongdoing in the wake of the nationwide racial reckoning after the killing of George Floyd by a Minneapolis police officer.

The city allowed University of Pennsylvania researcher Dr. Albert Kligman to conduct the dermatological, biochemical and pharmaceutical experiments that intentionally exposed about 300 inmates to viruses, fungus, asbestos and chemical agents including dioxin - a component of Agent Orange. The vast majority of Kligman's experiments were performed on Black men, many of whom were awaiting trial and trying to save money for bail, and many of whom were illiterate, the city said.
