Laird Maurice Wilcox was born November 28, 1942 in San Francisco, California. From 1961 to 1962, he attended Washburn University of Topeka, Kansas, and from 1963 to 1965 he studied at the University of Kansas, where he was a leader in the radical student movement of the 1960s. He served as editor and publisher of the Kansas Free Press, the University's first radical student newspaper of that period.

In 1964, Wilcox's collection of political ephemera earned first prize in KU's student book collecting contest. Emerging from that nucleus, the Wilcox Collection of Contemporary Political Movements was established at the University of Kansas in 1965, with Wilcox as its founder. Located in the University's Kenneth Spencer Research Library, with ongoing contributions by Wilcox, the collection contains thousands of books, pamphlets, serials, brochures, flyers, posters, and clippings, as well as correspondence and many audiotapes.

In 1966, Wilcox left the radical left but continued his avid research and publishing regarding political movements and ideologies. He has been widely featured by the media as an authority on the psychology of political extremism, ideological movements, mystical and religious belief systems, cults, and terrorism, including issues of civil liberties.

Wilcox is an active member of Mensa and a fellow of the Augustan Society. His many publications include The Wilcox Report; Civil Liberties Review; Guide to the American Left; Guide to the American Right; Guide to the American Occult; Spectrum: A Guide to the Independent Press and Informative Organizations; and Nazis, Communists, Klansmen, and Others on the Fringe; Political Extremism in America (co-authored with John George).
