February 12, 1850 - February 5, 1934,Davis, who was born in Philadelphia, Pennsylvania, was educated at Harvard. He returned to teach there in 1877 after a period as a meteorologist in Argentina and as an assistant with the North Pacific Survey. He became professor of physical geography in 1890 and of geology in 1898. Davis is acknowledged as the founder of geomorphology, the study of landforms. In his The Rivers and Valleys of Pennsylvania (1889) he first introduced what later became known as the Davisian systems of landscape analysis. His aim was to provide an explanatory description of how landforms change in an ideal situation and his most important contribution to this was his introduction of the cycle of erosion into geographical thought. He proposed a complete cycle of youth, maturity, and old age to describe the evolution of a landscape. In youth rivers occupy steep V-shaped valleys while in old age the valleys are broad. The end product would be a flat featureless plain he called a epeneplaine. This was an ideal cycle but in practice the cycle would invariably be interrupted by Earth movements. It was, nevertheless, strongly attacked by German geographers who objected to it on the grounds that it neglected such vital factors as weathering and climate in transforming the landscape. They also believed him to be undermining their argument that landforms could only be discovered by local fieldwork and the production of regional monographs. Davis also produced an influential work,  Related Paintings of William Morris Davis :. | Loing Kanal | Portrait of Katharina von Boyra | Portrait of Maria Feodorovna | Still Life 1 | Oscar Miestchaninoff |

Forbes, Edwin
1839-1895 ,was an American landscape painter and etcher who first gained fame during the American Civil War for his detailed and dramatic sketches of military subjects, including battlefield combat scenes. Forbes was born in New York, studied under A. F. Tait, and began as an animal and landscape painter. During the Civil War, he was special artist for Frank Leslie Magazine. Many of the spirited etchings he drew during the conflict were later presented by General Sherman to the government. They are now preserved in the War Office at Washington because of their historic value. After the war, Forbes painted landscape and cattle scenes, among which are Orange County Pasture (1879) and Evening??Sheep Pasture (1881). In 1877 he was made an honorary member of the London Etching Club. He died in 1895 in Brooklyn and is buried in Green-Wood Cemetery.
