It was built in 1860 for Hannah Piatt-Grandin and remodeled around 1910.","why_significant":"The nomination argues significance under Criterion B for the house's association with Ralph Peters, a prominent figure in several Cincinnati-area railroad lines who lived there from 1885 to 1902. To a lesser degree, its remodeling from an 1860s country house into a Colonial Revival design reflects East Walnut Hills' change from rural estates to a well-to-do, semi-suburban neighborhood.","narrative":"Set close to winding Grandin Road in Cincinnati's Hyde Park area, this large frame house was built in 1860 for Hannah Piatt-Grandin, widow of banker and merchant Philip Grandin. It has a square plan, three stories, a standing seam metal gable roof, and dormers front and rear. Around 1910, under owners Hugo and Clara Kupferschmid, it was remodeled with a wraparound porch with paired Tuscan columns, a Federal Revival entrance, and a Palladian-style rear window. The central hall keeps an Italianate staircase. Its main historical link is Ralph Peters, who lived here from 1885 to 1902 while serving in several railroad and bridge company posts, and later became president of the Long Island Railroad. He also gave land nearby for the Convent of Notre Dame, now Summit Country Day School. The remodeling also reflects how large rural estates in the area gave way to a more fashionable, semi-suburban neighborhood in the early twentieth century.","period_of_significance":"1885-1902, 1910","architect_builder":"Unknown","architectural_style":"Colonial Revival (c. 1910 remodeling), with Federal Revival entrance and Italianate staircase","criteria":["B"],"status_note":"Listed as occupied, in excellent condition, and used as a private residence; the building has been altered.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:15.185723-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/84000134.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84000134/f4037bfb1c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84000134/f4037bfb1c-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Peters-Kupferschmid_House_site.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Peters-Kupferschmid_House_site.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71989261","wikipedia":"https://en.wikipedia.org/wiki/Peters%E2%80%93Kupferschmid_House","wikidata":"https://www.wikidata.org/wiki/Q14716782"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/peters-kupferschmid-house-84000134/"}
