Marc Dachy was one of the main specialists of the Dada art movement (Tristan Tzara, for example) and Surrealism (André Breton, as example).[4] He was the author of several works in the Dada/Surrealist field, one of them, Journal du mouvement Dada 1915-1923 (Journal of the Dada Movement 1915-1923), was awarded the Grand Prix du Livre d'Art in 1990 presented to Dachy by Jack Lang in the Louvre auditorium. Journal du mouvement Dada 1915-1923 was translated into English by Skira Rizzoli International. Other translations into English include his books Dada: The Revolt of Art, published by Harry N. Abrams, Inc in 2006 and The Dada Movement, published by Rizzoli in 1990.
Dachy's essay on JapaneseDadaism (the Mavo group) and Japanese neo-Dada extensions (Gutai) was published in Japan by Suiseisha. He had been a resident in Kyoto at Villa Kujoyama in 2000 to prepare his book Dada au Japon (PUF 2002).[5] Dachy also published previously unpublished works by Louis Aragon (from his Dada period) as part of the Contemporary Literary History Project, a selection of texts by Clément Pansaers in 1986 (published by Gérard Lebovici / Champ Libre), letters by Francis Picabia in 1988 (also published by Gérard Lebovici) and a book of interviews with Raymond Hains.
