Horowitz wrote several books with author Peter Collier, including four on prominent 20th-century American families. He and Collier have collaborated on books about cultural criticism. Horowitz worked as a columnist for ''Salon''.
From 1956 to 1975, Horowitz was an outspoken adherent of the New Left. He later rejected progressive ideas and became a defender of neoconservatism. Horowitz recounted his ideological journey in a series of retrospective books, culminating with his 1996 memoir ''Radical Son: A Generational Odyssey''. Provided by Wikipedia
