Thomas Hill was an English-born American artist of the 19th century. He produced many fine paintings of the California landscape, in particular of the Yosemite Valley. Hill and his family moved to San Francisco, California. With painter Virgil Williams and photographer Carleton Watkins, Hill made his first trip to the Yosemite Valley in 1865. The next year, Hill traveled to the East Coast and Europe. He established his family on the East Coast but continued to take sketching trips to the West Coast and to attend meetings of the San Francisco Art Association. He moved his family back to San Francisco in 1873. Hill made yearly sketching trips to Yosemite, Mount Shasta, and, back east, to the White Mountains. Hill ran an art gallery and art supply store. He briefly acted as the interim director for the SFAA School of Design and went to Alaska on a commission for environmentalist John Muir.
