Physician and philanthropist John M. Templeton Jr., whose family foundation supports work that explores connections between science and religion and awards one of the world's largest monetary prizes for individuals, died Saturday at age 75 at his home in Bryn Mawr, Pa., The Philadelphia Inquirer and The Washington Post report. The cause was cancer.
A pediatric surgeon and hospital executive, Mr. Templeton retired from medicine in 1995 to run the John Templeton Foundation, started in 1954 by his late father, and over two decades built its endowment from $28 million to $3.34 billion. The philanthropy has made gifts and grants totaling $966 million, focusing on what it calls "science and the big questions." Its $1.7 million Templeton Prize honors work that affirms life's spiritual dimension.
Leadership of the foundation is expected to stay within the family, which delayed announcing Mr. Templeton's death until after Monday's presentation of the 2015 prize to Jean Vanier, the founder of an international network of communities for people with intellectual disabilities.
