The architect and builder are unknown.","why_significant":"The nomination argues the house is the best and most completely preserved example of Victorian Italianate architecture in Wyoming. It is also tied to John Tangeman, owner of Tangeman Paper in Lockland, who was one of the mill owners who built estates in Wyoming. He helped found the Wyoming Baptist Church.","narrative":"Built around 1857, this two-story brick house at 550 Larchmont in Wyoming, Ohio, is regarded as the community's finest and best-preserved example of Victorian Italianate design. It is a rectangular block with a smaller rear wing, a stone-framed central doorway with a semicircular fanlight and sidelights, floor-length ground-floor windows, cornice hoods on consoles, and a veranda with chamfered pillars and lattice segmental arches. A wide eave rests on brackets with double acorn pendants. The house sits on a hilltop above a stream, reached by a lane, and its frontal approach gives a vivid impression of pre-Civil War Ohio. It was built by John Tangeman, owner of the Tangeman Paper Company in Lockland. He was among the mill owners who established Wyoming as a suburb for the neighboring canal and industrial town, and he helped found and fund the Wyoming Baptist Church. He is known to have lived here until at least 1891, and his son William remained until after 1911.","period_of_significance":null,"architect_builder":null,"architectural_style":"Victorian Italianate","criteria":["A","C"],"status_note":"Used as a residence; interior and exterior condition listed as excellent, with a rear addition and alterations that have minimal impact on the historic appearance.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.946005-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/86001650.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86001650/e504d79afc-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86001650/e504d79afc-1600.webp","licence":"CC BY 3.0","author":"Photo by Greg Hume (Greg5030)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:JohnTangemanHouseLR.jpg\" rel=\"noopener\">Photo by Greg Hume (Greg5030)</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:JohnTangemanHouseLR.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986422","wikipedia":"https://en.wikipedia.org/wiki/John_Tangeman_House","wikidata":"https://www.wikidata.org/wiki/Q6260218"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/tangeman-john-house-86001650/"}
