Hayter was a painter and printmaker associated with Surrealism in the 1930s and Abstract Expressionism from 1940 onward. Regarded as one of the most significant printmakers of the 20th century, Hayter founded the legendary Atelier 17 studio in 1927. He is known 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. He worked with numerous notable artists including Alberto Giacometti, Joan Miró, Pablo Picasso, and Mark Rothko both outside and inside his atelier. Beyond his printing prowess, Hayter was equally as active as a painter, inventing some of the most central and significant images of the century before his artistic counterparts, through his constant work in drawing, engraving, collage, and low relief.
