Dufrene, along with Gil J Wolman and Brion Gysin, was one of the stalwarts of the experimental poetry in France. Dufrene's abstract poetry has led many to regard him as a member of the first generation sound poets - following in the footsteps of Filippo Tommaso Marinetti, Richard Huelsenbeck, Hugo Ball, Tristan Tzara, Kurt Schwitters and Antonin Artaud (among others).
Francois Dufrene joined Isidore Isou and the Lettrist movement in 1946 and continued to participate until 1964. Dufrene's talent was evident in the fact that he was already a member of the Lettrist Group at only 16 years old.
Dufrene became friends with Yves Klein in 1950 and with Raymond Hains and Jacques Villeglé in 1954. In 1957 he discovered décollage and in 1960 - with Pierre Restany, Yves Klein, Jean Tinguely, Arman, Hains and Villeglé - and helped found the art group known as Nouveau réalisme. He is considered one of the important artists in that Neo-Dada art movement.Wikipedia
