The Horace G. Simpson collection consists of photographs and drawings relating to Simpson’s education and to competition entries by the firm Wood & Simpson. Photographs include images of Simpson’s second place drawings for the 1908 Rotch Scholarship Competition and a group photograph that may be a class picture. Student work includes drawings from the 1907 and 1908 Rotch competitions, a study for a New York hotel, and a perspective drawing of a skyscraper. Drawings from the firm Wood & Simpson are primarily competition entries for public buildings such as the San Francisco Civic Center and the Santa Barbara County Courthouse. The collection also contains two volumes of full-size details illustrating building in Italy, Greece, France, and Venice.
