Lenore Krassner (October 27, 1908 – June 19, 1984), known professionally as Lee Krasner, was an influential American abstract expressionist painter in the second half of the 20th century. Krasner's career as an artist began when she was a teenager. She specifically sought out enrollment at Washington Irving High School for Girls since they offered an art major. After graduating from high school, she attended The Cooper Union on a scholarship, and completed the course work required for a teaching certificate in art. By 1928, she enrolled in the National Academy of Design. She also briefly attended the Art Students League of New York in 1928. In the 1930s, she began studying modern art through learning the components of composition, technique, and theory. This initial investigation into modern art formed her work throughout the rest of her career.
Krasner was very involved with the Artists Union and later joined the American Abstract Artists. She met future abstract expressionists Willem de Kooning, Arshile Gorky, Franz Kline, Adolph Gottlieb, Mark Rothko, Barnett Newman, Clyfford Still, and Bradley Walker Tomlin through this organization. Throughout her career, she refused to adopt a singular, recognizable style and instead embraced change through varying the mood, subject matter, texture, materials, and compositions of her work often. Lee Krasner and Jackson Pollock established a relationship in 1942 after they both exhibited at the McMillen Gallery. They married in 1945. Six months after Krasner’s death in1984, the Museum of Modern Art (MoMA) in New York City held a retrospective exhibition of her work. After her death, her East Hampton property became the Pollock-Krasner House and Studio, and is open to the public for tours. A separate organization, the Pollock-Krasner Foundation, was established in 1985. The Foundation functions as the official Estate for both Lee Krasner and Jackson Pollock, and also, under the terms of her will, serves "to assist individual working artists of merit with financial need."
