• Political Activist Pierre Guillaume, 1941
  

Pierre Guillame's name is associated with La Vieille Taupe, which was an ultra left bookstore founded in 1965 and closed in 1972. The name was taken over by Guillame in 1979 for the distribution of Holocaust denial books.

From 1957 to 1959 he prepared for archery at the École spéciale militaire de Saint - Cyr at the Prytanée National Militaire, and became eligible, but changed his mind. He joined Socialisme ou Barbarie, without playing a "remarkable role" according to the account of Cornelius Castoriadis. He fought in the Algerian War. In 1965, with the help of Jacques Baynac, he opened the Vielle Taupe bookstore, which was linked to the group Pouvoir ouvrir, a French anti - Marxist group.

In September 1967, while his exclusion was imminent, Guillame and Beynac left Pouvoir ouvrir, followed by most of the young members of the group. Then, La Vieille Taupe became the name of a small, informal group of people interested in studying the ultra left, Situationist International and Rosa Luxemburg. The Bookstore La Vieille Taupe sells books that are fundamental to these movements.

In 1980, Guillaume edited the Noam Chomsky essay "Some Elementary Comments on the Rights of Freedom of Expression" and the 1996 Roger Garaudy book The Founding Myths of Modern Israel.

The politics of Guillaume and other ultra left Holocaust deniers (including Serge Thion and Paul Rassinier) have been characterized as "anarcho - Marxist." According to Alain Finkielkraut, Guillaume's commitment to Holocaust denial stemmed from his ultra left politics, rather than from antisemitism. The genocide of the Jews was seen by Guillaume and others as a distraction from class struggle, and as playing into the hands of Zionist and Stalinist ideologies, and was hence denied.
