The American architectural firm Greene & Greene was a partnership between the brothers Charles Sumner Greene (1868-1957) and Henry Mather Greene (1870-1954). The firm, established in 1894, was officially dissolved in 1922, after which the two practiced independently. They were active in Southern California and were part of the American Arts and Crafts Movement. During the years 1907-1909 the Greenes created some of their most renowned residences, including the Blacker, Gamble, Pratt, and Thorsen houses. They also designed interiors, creating furniture, lighting, carpets, and stained glass for their clients.

The Greene & Greene Architectural Records and Papers Collection spans the years ca. 1896 - ca. 1963. The collection chiefly consists of architectural drawings (approximately 5,000) and also includes photographs, personal papers, and other manuscript material. Access to digital images of all the architectural drawings and to selected photographs are provided in the finding aid and through seven indexes: Images, Genre/Form, Geographic, Persons, Subjects, Corporate Names, and Projects.
