Jacques Baron (1905–1986) was a French surrealist poet whose first collection of poems was published in Aventure in 1921. Although he was initially involved with the Dada movement, he became a founding member of the Surrealist movement following his meeting with André Breton in 1921,^[1] and contributed to La Révolution surréaliste. In 1927, like many of his contemporaries, Baron joined the Cercle Communiste Démocratique.^[2] Although fascinated by dream-like states of the nomadic unconscious and other imaginary worlds of the "marvelous", a dispute with Breton in 1929 got him expelled from the movement, and prompted him to contribute to Un Cadavre, an anti-Breton pamphlet. After the break with Surrealism, Baron became associated with Georges Bataille and Documents,^[3] in which he published a short essay on "Crustaceans for the Critical Dictionary" (1929, issue 6), an article on the sculptor Jacques Lipchitz (1930, issue 1), and a poem dedicated to Picasso, "Flames" (1930, issue 3). He later collaborated on a number of reviews such as Le Voyage en Grèce, La Critique Sociale and Minotaure. Baron also wrote a novel, Charbon de mer (1935), a mémoire, L’An 1 du Surréalisme (1969), and a collection of poems, L’Allure poétique (1973).
