Hudson river school

The Hudson River School was a mid-19th century American art movement by a group of landscape painters, whose aesthetic vision was influenced by romanticism. Their paintings depict the Hudson River Valley and the surrounding area, as well as the Catskill Mountains, Adirondack Mountains, and White Mountains of New Hampshire. Note that "school" in this sense refers to a group of people whose outlook, inspiration, output, or style demonstrates a common thread, rather than a learning institution.
