Hardway, with an east wing added in 1929.","why_significant":"It is significant under Criterion C as a key Cleveland work of architect George J. Hardway, whose simple, functional design stood apart from the more ornate factories of the day. It survives as the only known Cleveland industrial building by Hardway and as a largely intact example of early 20th century industrial architecture. Secondary importance lies in its role housing a long-lived dental manufacturer.","narrative":"Built in 1903 on a corner lot in a residential part of Cleveland, this three-story brick factory was designed by architect George J. Hardway for the Cleveland Dental Manufacturing Company. Its red brick walls, sandstone trim, segmental-arched ranks of windows and projecting piers that rise above the parapet give it a plain but carefully proportioned look at a time when many factories were more ornate. An east wing was added in 1929 with finer wire-cut brick. The company, founded in 1893, made dental tools and instruments and was sold to a New York firm in 1959; manufacturing at this site ended in the 1970s. Hardway was primarily a residential architect, and this is the only Cleveland industrial building known to be his. The structure used slow-burning mill construction with heavy timber and fireproof vaults. It was rehabilitated in 2002-03 into loft apartments while keeping its open interiors and original window sash.","period_of_significance":"1903-ca. 1950","architect_builder":"George Hardway","architectural_style":"Late 19th and 20th Century American Movements: Commercial Style","criteria":["C"],"status_note":"Rehabilitated in 2002-03 and converted to loft apartments, with interior partitions kept to a minimum; described as in excellent condition.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.196248-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/04000936.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04000936/a013fda065-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04000936/a013fda065-1600.webp","licence":"CC BY-SA 3.0","author":"Cricchetti","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Cleveland_Dental_Manufacturing_Company_Building_1.JPG\" rel=\"noopener\">Cricchetti</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Cleveland_Dental_Manufacturing_Company_Building_1.JPG"},"district":{"nrhp_refnum":"15000371","name":"Scranton South Side Historic District (Additional Documentation)","url":"https://nationalhistoricalregister.com/districts/ohio/scranton-south-side-historic-district-additional-documentation-15000371/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987373","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q137649920"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/cleveland-dental-manufacturing-company-building-04000936/"}
