French anthropologist Claude Lévi-Strauss, in an interview in 1971, spoke about Breton's skill in determining the authenticity of objects. Strauss even described their friendship while the two were living in New York: "We lived in New York between 1941 and 1945 in a great friendship, running museums and antiquarians together. I owe him a lot about the knowledge and appreciation of objects. I've never seen him [Breton] doing a mistake on exotic and unusual objects. When I say a mistake, I mean about its authenticity but also its quality. He [Breton] had a sense, almost of divination."
