In 1950, she took a famous photo of the pioneers of Abstract Expressionist painting, including Jackson Pollock, Barnett Newman, Wiliem de Kooning, and Mark Rothko. Leen was also interested in other subjects, especially animals. In 1970, she published an entire book on bats. She would go on to publish 15 more books during her career.
