Charles “Chuck” Feeney, a retail entrepreneur and investor who amassed a multibillion-dollar fortune and then gave it all away, has died. He was 92 years old.

According to the Atlantic Philanthropies, Feeney’s foundation, he died peacefully in San Francisco on Monday.

Co-founding Duty Free Shoppers, an airport duty-free store chain that specializes in luxury goods in 1960 with a Cornell University undergraduate classmate, Feeney made much of his fortune.

In 1996, Feeney sold his shares in DFS to French luxury goods conglomerate LVMH, which now owns the retailer’s majority stake. According to the brand’s website, DFS has more than 850 boutiques across multiple continents.

The Atlantic Philanthropies reports Feeney advocated “Giving While Living,” believing he could make more difference by giving while living than by setting up a foundation after his death.

Feeney said in his biography “The Billionaire Who Wasn’t” that it’s much more fun to give while you’re alive than after you’re gone.

According to the foundation, Feeney founded Atlantic Philanthropies in 1982 and transferred all of his business assets to it two years later. After giving away all its funds successfully, the foundation closed its doors in 2020.

A total of $8 billion was granted by the Atlantic Philanthropies across five continents – much of it anonymously. A variety of causes were supported by donations, including education, health care, and human rights. Among the foundation’s donations are infrastructure in Vietnam, educational facilities in Ireland, and medical centers dedicated to finding cures for cancer and heart disease.
