Hans Richter's Dada: Art and Anti-Art was a landmark publication. First published in English in 1965, it completely changed the interpretation of Dada from a literary phenomenon to an artistic one. Ever since, it has been the first port of call for anyone interested in the subject. As a member of the first Dada group in Zurich during the First World War, Richter was in a unique position to tell its history, and his book drew together not only important historical documents but the testimonies of friends, such as Marcel Duchamp, Max Ernst and Raoul Hausmann. The compelling nature of his narrative has continued to inspire artists and historians.To celebrate one hundred years of Dada, Thames & Hudson is reissuing this unique document exactly as it first appeared in an expanded centenary edition. This edition features a new introduction telling the story of how the book came about and an extended commentary that identifies Richter's sources and brings the study up to date for a new generation of readers.
