Thomas Moran from Bolton, England was an American painter and printmaker of the Hudson River School in New York whose work often featured the Rocky Mountains. Moran and his family took residence in New York where he obtained work as an artist. He was a younger brother of the noted marine artist Edward Moran, with whom he shared a studio. A talented illustrator and exquisite colorist, Thomas Moran was hired as an illustrator at Scribner's Monthly. During the late 1860s, he was appointed the chief illustrator for the magazine, a position that helped him launch his career as one of the premier painters of the American landscape.
Moran along with Albert Bierstadt, Thomas Hill, and William Keith are sometimes referred to as belonging to the Rocky Mountain School of landscape painters because of all of the Western landscapes made by this group.
