Brooke produced numerous other genre pieces during his career, most notably A Dog Swap; he seems, however, to have preferred to paint landscapes instead of genre pieces, and spent much time depicting the landscape around Warrenton.[1] With William Henry Holmes, Edmund Clarence Messer, James Henry Moser, and Max Weyl, among others, he formed a group, sometimes referred to as the "Washington Landscape School", whose paintings were inspired by the Barbizon school and by the then-contemporary work of Dutch painters.[2] He also achieved a great deal of success as a portraitist.[3] Over 200 of his paintings and drawings were lost when a fire swept Warrenton in 1909 and destroyed his summer studio, at which he had gathered many paintings in preparation for an upcoming exhibition.[11]
