Thomas Moran (Bolton, England, February 12, 1837 – Santa Barbara, California, August 25, 1926) was an English-born American painter. Moran was born in Lancashire, UK, and raised in Philadelphia. He was a member of "The Hudson River School". During his extensive travels, Moran created hundreds of open-air artworks.
Best known for his panoramic views of the American West, Moran demonstrated the breadth of his vision in equally accomplished paintings of the Pennsylvania countryside, the landscape of Long Island, industrial complexes in Mexico and America, views of Venice,Italy, and numerous seascapes.
Moran was an artist of broad interests included paintings based on historical and literary works, marine subjects, pastoral views, and, surprisingly, urban and industrial scenes. In the 1880s Moran's long-time enthusiasm for marine painting grew stronger following his move to East Hampton, Long Island, where he could study the sea in all its moods. 
In 1862, Moran married Mary Nimmo.
