Asher Brown Durand was an American painter of the Hudson River School. His interest shifted from engraving to oil painting around 1830 with the encouragement of his patron, Luman Reed. In 1837, he accompanied his friend Thomas Cole on a sketching expedition to Schroon Lake in the Adirondacks and soon after he began to concentrate on landscape painting. He spent summers sketching in the Catskills, Adirondacks, and the White Mountains of New Hampshire, making hundreds of drawings and oil sketches that were later incorporated into finished academy pieces which helped to define the Hudson River School.
