Robert H. Orr.
Listed by the State Board of Architecture from 1920. 6 houses on record, 5 standing.
The State Board of Architectural Examiners' 1961 roster prints him as Orr, Robert H., certificate B 509, among the architects licensed from 1901 to 1929 (p. 68). The California State Board of Architecture's reports of 1920, 1923 and 1926 list him with certificate B 509. The documents behind this record name him as the architect of 6 houses in Claremont and Pomona, built from 1907 to 1915; for 5 of them, the Los Angeles County Assessor's record at the same address confirms the house standing.
Every house on record.
Standing houses first, then the rest, each with the name as the documents print it, the builder and the first family where a document names them, and every document behind it.
