Asher B. Durand drew a lot of his inspiration from the writings of critic John Ruskin and poet William Cullen Bryant who believed in careful observation of nature.
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.
Durand is particularly remembered for his detailed portrayals of trees, rocks, and foliage. He was an advocate for drawing directly from nature with as much realism as possible. Durand wrote, "Let [the artist] scrupulously accept whatever [nature] presents him until he shall, in a degree, have become intimate with her infinity...never let him profane her sacredness by a willful departure from truth."
