Jackson Pollock
Pollock was introduced to the use of liquid paint in 1936 at an experimental workshop operated in New York City by the Mexican muralist David Alfaro Siqueiros. He later used paint pouring as one of several techniques on canvases of the early 1940s, such as "Male and Female" and "Composition with Pouring I." After his move to Springs, New York, he began painting with his canvases laid out on the studio floor, and he developed what was later called his drip technique.
