In 1982 Charles Feeney established in Bermuda the foundation that would become Atlantic Philanthropies. In 1984, he transferred to the foundation his 38.75 percent stake in the company he had co-founded, Duty Free Shoppers. Since there was no sale, the company’s value was speculative, but some estimates said it may have exceeded $500 million. When he and a partner sold their interest in Duty Free Shoppers to Louis Vuitton Moët Hennessy in 1997, legal filings put the value of his share at $1.6 billion and said it belonged not to Mr. Feeney but to his philanthropic entity. In December 2016, with his donation of $7 million to his alma mater, Cornell University, for student community-service work, Chuck Feeney officially emptied the Atlantic Philanthropies’ accounts.With virtually all of his fortune gone, Mr. Feeney officially shut down Atlantic Philanthropies in 2020.
