It is also significant for its association with Porter Sheldon, a prominent attorney, congressman and founder of the American Aristotype Company, an early major producer of improved photographic paper.","narrative":"Perched on a knoll above the Chadokoin River Valley in Jamestown, New York, this three-story frame house at 70 Prospect Street began as a two-story Italianate dwelling built by carpenter Joel Partridge between about 1850 and 1867. Attorney and politician Porter Sheldon bought it in 1871, extended the south wing, added a mansard roof to unify the exterior, and remodeled the interior around 1880. Two Ionic porticoes in Classical Revival style were added in the early twentieth century. The exterior features patterned slate, decorative eave brackets, round-arched dormers and a mansard-roofed front porch with iron cresting. Inside, parquet floors, hardwood molding, carved stair details and ornate mantels survive largely intact. Sheldon served a term in Congress and founded the American Aristotype Company, an early major maker of improved photographic paper later bought by George Eastman. The house was recognized for its architecture and for its link to Sheldon.","period_of_significance":"1865-1932","architect_builder":"unknown","architectural_style":"Late Victorian/Second Empire/Mansard","criteria":["B","C"],"status_note":"Historic function was a single dwelling; current function is listed as social/meeting/bed and breakfast.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.502975-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/00000572.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000572/1bd8589c45-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000572/1bd8589c45-1600.webp","licence":"Public domain","author":"Pubdog (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Partridge-Sheldon_House_Nov_10.JPG\" rel=\"noopener\">Pubdog (talk)</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Partridge-Sheldon_House_Nov_10.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316776","wikipedia":"https://en.wikipedia.org/wiki/Partridge-Sheldon_House","wikidata":"https://www.wikidata.org/wiki/Q7140811"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/chautauqua-county/partridge-sheldon-house-00000572/"}
