B. Clark.","why_significant":"The house is significant at the state level under Criterion B for its association with Dr. Frank Mace MacFarland, a major contributor to the early development of marine biology in California. He was a Stanford professor who studied opisthobranch mollusks and carried out much of that work in a laboratory built into the house. His monograph remains a foundation for the taxonomy of Pacific Coast opisthobranchs.","narrative":"Built between 1910 and 1914 on a one-acre site in Stanford's San Juan Hill faculty housing tract, this two-story residence was designed by Palo Alto architect A. B. Clark. Its picturesque look comes from a rolled, faux-thatch shingle roof, heavily textured stucco walls, paired casement windows and exposed rafter tails, combining Tudor Revival massing with Craftsman and Neo-colonial details. A detached garage and later additions from 1924 and 1981 are counted as contributing, while a 1960s pool, spa and pool house are not. The house is tied to Dr. Frank Mace MacFarland, a Stanford professor from 1909 until 1934 and a leading figure in California marine biology. He set up a first-floor laboratory with original shelving, counters and a sink, where he studied sea slugs and his wife Olive painted the species. His monograph on Pacific Coast opisthobranchs, completed after his death in 1951, remains a standard reference. The property is significant at the state level for this association.","period_of_significance":"1914-1951","architect_builder":"Clark, Arthur Bridgman","architectural_style":"Late 19th and Early 20th Century American Movements: Craftsman and Other: Neo-classical (described as Tudor Revival with Neo-colonial and Craftsman details)","criteria":["B"],"status_note":"Described as relatively unaltered and in excellent condition, in use as a single dwelling, with additions from 1924, the 1960s and 1981.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.604518-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/06000659.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/06000659/d4d4583c0e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/06000659/d4d4583c0e-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MacFarland_House,_775_Santa_Ynez_St.,_Stanford,_CA_6-3-2012_3-23-08_PM.JPG\" rel=\"noopener\">Sanfranman59</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:MacFarland_House,_775_Santa_Ynez_St.,_Stanford,_CA_6-3-2012_3-23-08_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861732","wikipedia":"https://en.wikipedia.org/wiki/MacFarland_House_(Stanford,_California)","wikidata":"https://www.wikidata.org/wiki/Q55757589"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/santa-clara-county/macfarland-house-06000659/"}
