Willis Allison Carto (July 17, 1926–) is an American far-right activist, who has, throughout his career, promoted conspiracy theories featuring antisemitism; he also has questioned the role of the Trilateral Commission and the Council on Foreign Relations. He is affiliated with the American Free Press, The Barnes Review, Institute for Historical Review (which promotes Holocaust denial), and, in the past, affiliated with Congress of Freedom, Liberty and Property, Liberty Lobby, John Birch Society, National Youth Alliance, and the Populist Party (1984)
He is listed as an extremist individual by the Anti-Defamation League (ADL). According to the ADL, the transforming events of his life came from reading the racist theory works of Francis Parker Yockey; Revilo Oliver introduced Carto's remembrance of Yockey. In the early 1950s, he served as director of the Congress of Freedom, "which sought to build coalitions between racists and hard-right libertarians, and as executive secretary of Liberty and Property (which he founded).", and was editor of Right, "an information clearinghouse for racist and anti-Semitic activities".  Also motivating him was a leftist historian, Harry Elmer Barnes, who was, according to Murray Rothbard, "the father and the catalyst for all of World War II revisionism,"  who believed the Holocaust was a pretext to involve the U.S. in a European war.
The group published a newspaper entitled The Spotlight (subtitled "The Voice of the American Majority"). The Spotlight often included material that was anti-Semitic and racist, and was part of Carto's broader media appeal. He briefly owned, for example, part of Resistance Records, the leading distributor of white power hate music.
The Liberty Lobby closed operations in 2001.
Institute for Historical Review
He started the Barnes Review in 1994. At its 2002 conference, William Lind of the Free Congress Foundation, who decidedly is not a Holocaust denier, blamed "political correctness" and other evils on so-called "cultural Marxists..."These guys were all Jewish." The publication, in 2008, has, including in articles signed by Carto, emphasized Christian Identity.
He has written, in the Review, on the basis for his "Holocaust revisionism", saying his interest started with a 14 June 1959 letter to the editor of Our Sunday Visitor, by Steven F. Pinter, "who claimed to have been in Dachau for 17 months after the war as a U.S. government attorney and said there were no gas chambers there or in any other detention camp in Germany." He went on to describe Paul Rassinier as the first serious scholar.
