Schapiro (fig. 1.3), unlike Greenberg and Rosenberg, did not identify with a particular school or painter, but brought his rich knowledge of art history and theory to bear on the contemporary art scene. As a result, he exerted a dramatic influence on contemporary artists, notably de Kooning. In the 1950s and 1960s, the heyday of Abstract Expressionism, Schapiro, Rosenberg, and Greenberg were leading voices on art in the United States.
