David Horowitz, American activist and author

David Joel Horowitz (born January 10, 1939) is an American conservative writer. He is a founder and president of the right-wing David Horowitz Freedom Center (DHFC); editor of the Center's far-right website FrontPage Magazine; and director of Discover the Networks, a website that tracks individuals and groups on the political left. Horowitz also founded the organization Students for Academic Freedom.

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.
