The Council on Foreign Relations mourns the passing of David Rockefeller, CFR’s honorary chairman and a pillar of the institution for more than half of a century. Mr. Rockefeller was the longest-serving member of the Council, joining in 1941. He served on the board of directors for 36 years, 15 as chairman. In recognition of Mr. Rockefeller’s many intellectual, financial, and leadership contributions, the Council’s flagship Studies Program—a world renowned foreign policy think tank—was named in his honor. As a life-long philanthropist, business leader, and a fierce advocate for international cooperation, Mr. Rockefeller made extraordinary contributions to New York, the United States, and the world. His endearing personal qualities made him a beloved and widely respected man for all those who knew him. He will be truly missed. CFR offers its heartfelt condolences to his entire family.
