Stephens.","why_significant":"The nomination argues the property is a watershed design in Price's Arts and Crafts work, the first major commission in his Craftsman style and the house he later described as his ideal. It also argues the house is significant as the studio and home of two nationally known illustrators and as the home of civic leaders Allen Seymour and Mildred Scott Olmsted, who used it as a meeting place for social reform work.","narrative":"Built within a late eighteenth-century fieldstone banked barn, this artists' residence in Rose Valley, Delaware County, Pennsylvania, was remodeled in 1904 by architect William Lightfoot Price for the illustrators Alice Barber Stephens and Charles H. Stephens. The asymmetrical house combines quarried gneiss and flint, stucco over frame, and red Mercer ceramic tile, with two studios having large northern windows. A thunderbird motif in a fireplace and in tile gave the building its name. The property is regarded as a major early work of the Arts and Crafts movement in America and as Price's first large-scale new construction in the style he later promoted in his writings. The house also served from 1921 onward as the home of Allen Seymour and Mildred Scott Olmsted, who hosted informal meetings on racial equality, civil liberties, women's rights and peace. The grounds, with pergolas, a springhouse, a stable garage and a 1926 monument marking the Great Minquas Trail, are documented as retaining their original design.","period_of_significance":"c.1790, 1904-1938","architect_builder":"William Lightfoot Price (architect)","architectural_style":"Bungalow/Craftsman","criteria":["A","B","C"],"status_note":"The document states the complex retains complete integrity of Price's design, materials and landscaping, and that both studios are used by artist residents today.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.257184-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/89001053.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89001053/5d7d587191-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89001053/5d7d587191-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Thunderbird_RV.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Thunderbird_RV.JPG"},"district":{"nrhp_refnum":"10000470","name":"Rose Valley Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/rose-valley-historic-district-10000470/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998019","wikipedia":"https://en.wikipedia.org/wiki/Thunderbird_Lodge_(Rose_Valley,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q7799093"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/thunderbird-lodge-89001053/"}
