Just as the Beats brought innovation to the poetic form, Hartigan and other American abstract expressionists turning the painting world on its head following World War II. Often cited as the greatest female artist of the movement, Hartigan lived the final 40+ years of her life in Baltimore, where she was a major player in the art scene until her death in 2008.

"Perhaps the subject of my art is like the definition of humor — emotional pain remembered in tranquillity."
