Prints by Stanley William Hayter and Helen Phillips, May 12-June 17, 1956

Stanley William Hayter (December 27, 1901-May 4, 1988) was an English painter and master printmaker associated in the 1930s with surrealism and from 1940 onward with abstract expressionism. Regarded as one of the most significant printmakers of the 20th century, in 1927 Hayter founded the influential Atelier 17 studio in Paris. He is noted for his innovative work in the development of viscosity printing (a process that exploits varying viscosities of oil-based inks to lay three or more colors on a single intaglio plate). Hayter was equally active as a painter. Hayter married Helen Phillips in 1940 and they divorced in 1972.

Helen Elizabeth Phillips, also known as Helen Phillips Hayter was an American sculptor, printmaker, and graphic artist active in San Francisco, New York, and Paris. She was born on March 3, 1913 in Fresco, California. From 1932 to 1936, she studied at the California School of Fine Arts in San Francisco with Ralph Stackpole and Gottardo Piazzoni. In 1936, she won the school's Phelan Travelling Fellowship with which she funded a year of study in Paris. From 1936, she was associated with Atelier 17, an experimental and collaborative intaglio printmaking workshop founded by Stanley William Hayter in the heart of Montparnasse. The couple would marry in 1940 and divorce in 1972. During World War II, Phillips returned to the United States and began working within the emerging literary and artistic circles of the New York School. She executed sculptures in bronze, stone and wood and produced intaglio prints. Her work is often non-figurative, however, she also worked with semi-abstract, anthropomorphic forms in both print and three-dimensional media. She died on January 23, 1995 in New York City.
