Leonard Abramson, a former pharmacist who built U.S. Healthcare, one of the first health Maintenance organizations, and who used some of the nearly $1 billion he received from selling it to give generously to cancer research and other medical causes, died on July 4 at his home in Blue Bell, PA. He was 93.

During the 30 years following the sale of U.S. Healthcare, Mr. Abramson used his wealth for philanthropic causes: $100 million to establish the Leonard and Madlyn Abramson Family Cancer Research Institute at the University of Pennsylvania’s cancer center; later contributions to the cancer center brought the total to more than $140 million; $15 million to help start the Children’s Hospital of Philadelphia’s pediatric research center; $10 million to Temple University’s dental school; $2.5 million to the pediatric emergency department of the children’s hospital in King of Prussia, PA, and $10 million to the Jupiter Medical Center in Florida.
