This painting of the geyser Old Faithful was done by Albert Bierstadt. It is believed this scene was painted from sketches made by Bierstadt following a visit to Yellowstone National Park in July 1881. President Ulysses S. Grant established the park on March 1, 1872 with the signing of the Yellowstone National Park Protection Act. This law made Yellowstone the world's first national park. Bierstadt was among the Hudson River School artists of the 19th century. Bierstadt was renowned for his depictions of the American West and documenting Westward Expansion in the late 19th century. There are six pieces by Bierstadt in the White House Collection.
