Gabriel and Marcel Piqueray were identical twins, born in Brussels in 1920.  Surrealists, they associated with key figures of the movement, including André Breton and René Magritte (with whom they held regular “surrealist working meetings” for many years), as well as with the musician Chet Baker and the composer Francis Poulenc.  In 1957 they became joint editors of the influential avant-garde journal Phantomas, whose contributors included Samuel Beckett, Roland Barthes, René Magritte, Kurt Schwitters, and Jorge Luis Borges, among many others.  They published a dozen books together, always listing “Gabriel and Marcel Piqueray” as authors—the Piqueray brothers did not believe in individual authorship. Gabriel died in 1992 and Marcel five years later.
