Leo Castelli reigned for decades as America’s most influential art dealer. Not only was he elegant, shrewd, irresistible and an enigmatic figure, but the Castelli Gallery was also the leading center of new American art , and a lively meeting place for artists and critics including Rauschenberg, Lichtenstein, Warhol, and Twombly— to name a few. What’s more, like Anna Wintour in fashion, his opinion more than mattered.

Now Annie Cohen-Solal recounts his incalculably influential and astonishing life in Leo and His Circle.

Doesn’t get much artier.
