Raoul Vaneigem (born 1934) is a Belgian writer and philosopher. He was born in Lessines (Hainaut, Belgium). After studying romance philology at the Free University of Brussels (now split into the Université Libre de Bruxelles and the Vrije Universiteit Brussel) from 1952 to 1956, he participated in the Situationist International from 1961 to 1970. He currently resides in Belgium and is the father of four children.
Vaneigem and Guy Debord were two of the principal theoreticians of the Situationist movement. Vaneigem's slogans frequently made it onto the walls of Paris during the May 1968 uprisings. His most famous book, and the one that contains the most famous slogans, is The Revolution of Everyday Life (in French Traité de savoir-vivre à l'usage des jeunes générations).
