Albert Bierstadt
 (1830 - 1902) 

Albert Bierstadt was a German-American painter best known for his lavish, sweeping landscapes of the American West. He joined several journeys of the Westward Expansion to paint the scenes. He was not the first artist to record the sites, but he was the foremost painter of them for the remainder of the 19th century.
