William Mackay (artist)

William Andrew Mackay (1876 - July 26, 1939) was an American artist who created a series of murals about the achievements of Theodore Roosevelt. Those three murals, completed in 1936, were installed beneath the rotunda in the Roosevelt Memorial Hall of the American Museum of Natural History in New York. Less known but also important, he was a major contributor to the development of ship camouflage in the United States during World War I.
