William Bliss Baker, American painter (d. 1886)
William Bliss Baker (November 27, 1859 – November 20, 1886) was an American artist who began painting just as the Hudson River School was winding down. Baker began his studies in 1876 at the National Academy of Design, where he studied with Bierstadt and de Haas. He later maintained studios in Clifton Park, New York and New York City, where he painted in oils and watercolors. He completed more than 130 paintings, including several in black and white.

At age 26, Baker was just beginning to hit his stride as a landscape painter when he died at his father's house at Hoosick Falls, New York. The New York Times said that his death "deprived America of one of its most promising artists."
