Holmesburg Prison in Philadelphia became notorious for unethical medical experiments conducted on inmates from the 1950s through the 1970s. Prisoners, many of them poor and Black, were lured into participating with small payments; doctors also lied to prisoners about the risks. Under dermatologist Albert Kligman, inmates were exposed to chemicals, viruses, asbestos, and other toxic chemicals that caused lifelong physical and psychological damage. The horrors of this institution are why Holmesburg Prison was given the nickname, "The Terrordome."
