New York Times – October 11, 2023. Charles F. Feeney, a pioneer of duty-free shops and a shrewd investor in technology start-ups who gave away nearly all of his $8 billion fortune to charity, much of it as quietly as he had made it, died on Monday in San Francisco. He was 92. After piling up billions in business, he pledged to donate almost all of his money to causes before he died. He succeeded, and then lived a more modest life.
