Albert Montgomery Kligman (March 17, 1916 – February 9, 2010)[1] was an American dermatologist who co-invented Retin-A, the acne medication, with James Fulton in 1969.[2] Kligman performed human experiments on inmates at Holmesburg Prison in Philadelphia, which led to a well-documented scandal years later. The experiments intentionally exposed humans to pathogens and dioxin, and later became a textbook example of unethical experimenting on humans. He and others involved were sued for alleged injuries, but the lawsuit was dismissed due to the statute of limitations expiring.[1]
