Leonard Abramson (born 1932) is an American philanthropist, healthcare executive, and businessperson best known as the founder and former CEO of U.S. Healthcare, a pioneering managed care organization. Born in Pennsylvania to Jewish parents, he was raised in the Strawberry Mansion neighborhood of Philadelphia. Abramson attended the Philadelphia College of Pharmacy and Science, where he earned an undergraduate degree in pharmacy, supporting himself by driving a taxi during his studies. His career began as a retail pharmacist; while working for a hospital-management company, he created Family Medical Care, a prepaid medical plan, which he later purchased and renamed U.S. Healthcare in the late 1970s. He demonstrated early foresight into managed care models amid rising healthcare costs in the 1960s. Abramson has been actively involved in philanthropy, serving as former National Treasurer and a Governing Board member of the World Jewish Congress, where he is a major donor. He is a Trustee Emeritus of The Johns Hopkins University, and the Leonard and Madlyn Abramson Professorship in Neurodegenerative Diseases is named in honor of him and his wife, Madlyn.
