When Mort Zuckerman, the New York City real-estate and media mogul, lavished $200 million on Columbia University in December to endow the Mortimer B. Zuckerman Mind Brain Behavior Institute, he did so with fanfare suitable to the occasion: the press conference was attended by two Nobel laureates, the president of the university, the mayor, and journalists from some of New York’s major media outlets. Many of the 12 other individual charitable gifts that topped $100 million in the U.S. last year were showered with similar attention: $150 million from Carl Icahn to the Mount Sinai School of Medicine, $125 million from Phil Knight to the Oregon Health & Science University, and $300 million from Paul Allen to the Allen Institute for Brain Science in Seattle, among them. If you scanned the press releases, or drove past the many university buildings, symphony halls, institutes, and stadiums named for their benefactors, or for that matter read the histories of grand giving by the Rockefellers, Carnegies, Stanfords, and Dukes, you would be forgiven for thinking that the story of charity in this country is a story of epic generosity on the part of the American rich.
