Robert Bruce Crane (1857 – October 30, 1937) was an American painter. He united the Lyme Art Colony in the prematurely 1900s. His most active period, though, came after 1920, when for greater than a decade he did oil sketches of woods, meadows, and hills. He developed into a Tonalist painter under the touch of Jean-Charles Cazin at Grez-sur-Loing. Crane's period works were approximately always fall and winter scenes. He usually painted in his studio in Bronxville, New York, where afterward many of the Tonalists he relied mostly on memories of his external sketching experiences. Selected law can be found at the Florence Griswold Museum and the Newark Museum. He is a descendant of the Continental Congressman Stephen Crane.
