Marcel Duchamp (1887-1968) was arguably the most radically avant-garde artist of the twentieth century. In 1918, Duchamp made the most momentous decision an artist can make: he stopped painting altogether. He spent the rest of his life exploring alternatives to traditional artistic practice in a relentless effort to avoid repeating himself. As a result, Duchamp pioneered new ways of thinking about art and the artistic process that have inspired generations of artists. His inventiveness as a graphic designer, his wit in appropriating readymade objects as works of art, and his ability to create unique masterpieces out of reproductions made from his earlier work are brilliantly revealed in this important and richly illustrated study of the least understood aspects of Duchamp's artistic achievements. NB. Please note that the text of this book is in French, but the book has innumerable illustrations in both colour and black and white which will appeal to readers interested in the life and work of Marcel Duchamp.
