“This study is so good,” said one of her teachers, “you would not know that it was done by a woman.” That is what Lee Krasner dealt with, coming of age as an artist in the middle of the last century. Oh, and she was married to the protean painter Jackson Pollock. After his death in 1956, Lee Krasner went on to make her own mark as an Abstract Expressionist. This is her first European retrospective in over 50 years. —L.J.
