Leonard Abramson, health care pioneer and cancer research donor, dies at 93

Businessman and longtime philanthropist Leonard Abramson has died at 93. The University of Pennsylvania's Pearlman School of Medicine Dean Jonathan Epstein confirms he died on July 4th. Abramson notably founded U.S. Healthcare in 1975, one of the first health maintenance organizations. The company was bought by Aetna 20 years later and is now part of CVS Health. He and his late wife Madlyn gave over 140 million dollars to cancer research at Penn Medicine. The hospital's cancer center is named after the couple.
