Hugh De Musgrove Clay (August 27, 1834 - October 14, 1904), also known as Hugh M. Clay, was an English-American artist and chromolithographer based in Buffalo, New York. Clay arrived in the United States with his family when he was just 2. His earliest recorded work in Buffalo dates to 1854, when he was employed with the firm of Compton and Gibson. When Sage and Sons bought out Compton in 1856, they inherited Clay, who worked with them for several years. Starting in 1864, Clay partnered with Julius Herman Cosack (1826 - 1892), a fellow engraver for Sage, to found 'Clay and Cosack.' The partnership lasted until about 1877, when Clay left the firm. He subsequently partnered with Henry A. Richmond under the imprint of 'Clay and Richmond'. This firm lasted until 1886, when Clay retired and Richmond acquired the remaining stock, operating subsequently as 'Richmond Lithographing Company'. In 1896, Richmond Lithographing was bought out by Horace Reed and Hugo R. Munro, who renamed it the 'Niagara Lithograph Company', which operated well into the 20th century. Clay relocated to Manhattan, New York City in 1902, where he died in 1904.
