It is also tied to Charles P. Knox, who pioneered pre-granulated gelatin, and to his widow Rose M. Knox, who ran the Knox Gelatin Company from the house until her death in 1950.","narrative":"Built in 1898 at 104 West Second Avenue in Johnstown, this 30-room Classical Revival mansion was designed by the Chicago firm Peabody & Beauley for gelatin manufacturer Charles P. Knox and his wife Rose. A monumental portico with paired fluted Corinthian columns dominates the north facade, and the wood-frame house rises above a raised granite basement under a glazed terra cotta tile roof. Inside are a mahogany staircase, pocket doors, built-in seating, and a library trimmed in ebony. A 1908 addition by Utica architect Linn Kinne added a living room and greenhouse. The house is listed for its architecture and for its association with the Knoxes. Charles Knox pioneered the commercial sale of granulated, unflavored gelatin. After his death in 1908, Rose Knox managed the company from the residence until her death in 1950. The property stayed in Knox family ownership until the 1980s, which helped preserve its integrity. It now operates as a bed and breakfast inn.","period_of_significance":"1898-1950","architect_builder":"Peabody & Beauley; Linn Kinne (addition)","architectural_style":"Late 19th Century Revivals/Classical Revival","criteria":["B","C"],"status_note":"Current function is a bed and breakfast inn; the form describes the house as retaining an extraordinarily high level of integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.256957-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/08000101.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/08000101/2f2db1f46c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/08000101/2f2db1f46c-1600.webp","licence":"CC BY-SA 4.0","author":"Beyond My Ken","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Knox_Mansion_from_west.jpg\" rel=\"noopener\">Beyond My Ken</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Knox_Mansion_from_west.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75317868","wikipedia":"https://en.wikipedia.org/wiki/Knox_Mansion","wikidata":"https://www.wikidata.org/wiki/Q6423567"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/fulton-county/knox-mansion-08000101/"}
