Max Ernst's first Paris exhibition opened without him. At Au Sans Pareil on 2 May 1921, the Dada circle celebrated on the pavement — Philippe Soupault up a ladder with a bicycle, André Breton in the doorway — while Ernst, a German national refused a visa three years after the war, stayed in Cologne. The next year he solved the border his own way, entering France without papers on Paul Éluard's passport, and moving in with Éluard and his wife Gala — a ménage à trois the three of them kept for two years.
In Paris he became Surrealism's chief inventor of means: frottage, the pencil rubbing of floorboards and leaves that let images arrive by accident; grattage, its scraped-paint cousin; and the collage novel, cut and pasted from Victorian engravings. A 'degenerate' artist to the Nazis and an enemy alien to wartime France, he was interned at the Camp des Milles, escaped to America in 1941 with Peggy Guggenheim's and Varian Fry's help, and came back for good in 1953. He died in Paris in 1976, on the eve of his eighty-fifth birthday, and is buried at Père Lachaise.
