When Philip Johnson died in 2005 at the age of 98, he was still one of the most recognizable and influential figures on the American cultural landscape, a consummate power broker and shaper of public opinion. Defining the concept of "starchitecture," Johnson introduced European modernism to America—the sleek, glass-and-steel architecture that now dominates our cities—and mentored generations of architects, designers, and artists to follow. But as Mark Lamster reveals in this biography, Johnson was also a man of deep paradoxes: he was a Nazi sympathizer, a designer of synagogues, a populist, and a snob, whose clients ranged from the Rockefellers to televangelists to Donald Trump.
