Jackson Pollock was an American painter born in 1912 who is considered one of the most influential figures of Abstract Expressionism. He is famous for developing a technique known as "action painting" where he poured and dripped paint onto canvases laid out on the floor from all directions, which came to be called the "drip technique." Some of his most famous paintings using this style include Convergence from 1952 and N°5 from 1948. Pollock died in 1956 at the age of 44 in a car accident.
