Chuck Feeney

Feeney, co-founder of Duty Free Shoppers, secretly transferred almost his entire stake to his Atlantic Foundation in 1984 and lived modestly while it gave around eight billion dollars to universities, health and human rights work, often anonymously. He then decided to spend the foundation down while he was alive; Atlantic Philanthropies made its final grants in 2016 and closed in 2020. He died in 2023.
