The passing of Sir John Templeton provides an opportunity to reflect on “The Big Questions” that were the focus of his philanthropic work.

Templeton, one of the world’s leading investors and philanthropists, died today in Nassau, Bahamas. He was 95. A native of Tennessee, he was knighted by Queen Elizabeth II in 1987 for the philanthropic work he pursued in his encore career.

In 2006, the John Templeton Foundation helped establish The Purpose Prize to recognize social innovators over 60 with awards of up to $100,000, and remains a major funder. (The Purpose Prize is a project of Civic Ventures, publisher of Encore.org.)
