John Phillips Marquand was an American writer. Originally best known for his Mr. Moto spy stories, he achieved popular success and critical respect for his satirical novels, winning a Pulitzer Prize for The Late George Apley in 1938. One of his abiding themes was the confining nature of life in America's upper class and among those who aspired to join it. Marquand treated those whose lives were bound by these unwritten codes with a characteristic mix of respect and satire. No. 1 on The New York Times Fiction best seller list for 1 week, from the issue of April 24, 1939. Wiki link
