I moved to New York in 1963. There, I studied print making and worked as a shop monitor at the Pratt Graphic Art Center. One night on the way home, I picked up a discarded time clock from the street. I looked at it for months in my apartment on the Lower East side before moving to a loft near the Brooklyn Bridge in 1964. There, I finally painted it. This found object, with its intricate gears and levers, was a pattern of shapes that summed up what I was trying to do in my previous painting.
