Nicholas Fox Weber, author of the acclaimed Patron Saints (“Exhilarating avant-garde entertainment”—Sam Hunter, The New York Times Book Review) and Balthus (“The authoritative account of his life and work”—Michael Ravitch, Newsday), gives us now the idiosyncratic lives of Sterling and Stephen Clark—two of America’s greatest art collectors, heirs to the Singer sewing machine fortune, and for decades enemies of each other. He tells the story, as well, of the two generations that preceded theirs, giving us an intimate portrait of one of the least known of America’s richest families.
