His father was a graphic artist who encouraged his interest in art.

A visit to Paris in 1928–29 inspired his own version of Cubism ; he began rearranging natural forms from everyday life into flat posterlike patterns with sharp outlines and contrasting colours
the dissonant colours and repetitive rhythms reflecting his interest in jazz
in a style that eventually led to totally abstract patterns. He is considered the outstanding U.S. artist who worked in the Cubist style.
