Jimmy Ernst (1920-1984), son of Surrealist Max Ernst, was an American artist and a prominent figure in the New York avant-garde in the mid 20th century. Born Hans Ulrich Ernst in Cologne, Germany, he studied printing and typography and later immigrated to the United States in 1938.
During his time in New York, he experimented with the Surrealist method of automatism and developed his own technique called sifflage, which involved blowing viscous paint over a canvas. The artist combined this method with his interest in jazz music and improvisation in his works. He was a member of The Irascibles group and became a member of the American Academy and Institute of Arts and Letters in 1983.
