Marcel Duchamp
From 1956 to 1967, Stauffer entered into a lengthy correspondence with Marcel Duchamp, whose work he explored in great detail. His extensive research on Duchamp led to the publication in 1973 of the book "Ready Made – 180 Aussprüche aus Interviews mit Marcel Duchamp". This was followed in 1981 by "Die Schriften – Zu Lebzeiten veröffentlichte Texte mit übersetzten und faksimilierten Texten von Marcel Duchamp", which Stauffer co-edited with Theo Ruff. The volume "Marcel Duchamp: Interviews und Statements" was published posthumously in 1992.
