His [Marcel Duchamp's] idea was that anything could be art by focusing the mind to think of it as art. My images are similar but at the time my work was first being shown, 1958-'59, I was unfamiliar with Duchamp and Dada. Everyone said my work was Dada, so I read on it, went to Philadelphia to see the Arensberg Duchamp collection, was delighted by it and later met him (Duchamp)... But it was all more a coincidence. Perhaps it's that certain ideas get into the air, ideas that come out of our living and out of the environment automatically
