Ernest George Washington Dietrich, AIA (February 22, 1857 – December 24, 1924) was an American architect. Born and raised in Pittsburgh, Pennsylvania, Dietrich relocated to New York City in 1886[1] where he practiced for nearly forty years. His work included the design of churches, libraries, hotels, commercial and public buildings, but he is most highly regarded for his residential designs in the shingle, colonial revival, and arts and crafts styles. In cooperation with furniture designer Gustav Stickley, Dietrich designed the first "Craftsman House" published in The Craftsman magazine in May 1903.[2]
