Henry Coston (1910-2001) is among the most well-known of antisemitic writers in the history of twentieth century French antisemitism. Centered on the second part of his career (from the 1950s until his death) this article is a presentation of the editorial policies put into place by Coston as editor of La Libre Parole, and looks to the ways in which he adapted his antisemitism as necessary according to changing circumstances. Coston was both a magazine editor (Lectures francaises) and a book editor (La librairie francaise). He was also the author of dozens of brochures and books, analyzed here through the references and methodologies that he used, the antisemitic discourses that he developed and, finally, the impact of his writing in France and abroad (Europe and the Americas).
