Henn and designed by Cleveland architect Earl J. Andrews. It sits in the northeast corner of Sims Park on Lake Erie.","why_significant":"The nomination argues it is significant under Criterion B as the longtime home of Albert W. Henn, a founder and president of the National Acme Company. Under Criterion C it is a Tudor Revival house with Bungalow/Craftsman overtones, the only known Euclid work of architect Earl J. Andrews and one of the last large houses on the city's lakefront.","narrative":"Overlooking Lake Erie from the corner of Sims Park in Euclid, Ohio, this large brick residence was built in 1923 for Albert W. Henn, a Cleveland industrialist. Henn helped found the National Acme Company, a machine tool builder that by 1942 ranked as the nation's fifth largest, and served as its president from 1918 to 1925. He lived here until 1945. Cleveland architect Earl J. Andrews designed the house, blending Tudor Revival character with Bungalow/Craftsman features such as flared corner buttresses and shingled sleeping porches. Walls of modified Roman brick, a slate roof, sandstone lintels, extensive millwork and six fireplaces reflect careful craftsmanship, and the original plan and finishes remain largely intact inside. It is the only known Andrews design in Euclid and one of few large lakefront houses to survive postwar development. The city assumed ownership after 1945, and later work repaired the roof, lighting, floors and entrances.","period_of_significance":"1923-1945","architect_builder":"Andrews, Earl J.","architectural_style":"Tudor Revival; Bungalow/Craftsman","criteria":["B","C"],"status_note":"Owned by the City of Euclid; the current function is listed as Social/Recreation/Cultural, and the form describes recent restoration work such as repainting, floor refinishing, roof repair and waterproofing.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.55518-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/00000422.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000422/fcb4eeed76-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000422/fcb4eeed76-1600.webp","licence":"CC BY-SA 3.0","author":"NorthCoastReader","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Albert_W._Henn_Mansion_-_Euclid,_Ohio.JPG\" rel=\"noopener\">NorthCoastReader</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:Albert_W._Henn_Mansion_-_Euclid,_Ohio.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987909","wikipedia":"https://en.wikipedia.org/wiki/Albert_W._Henn_Mansion","wikidata":"https://www.wikidata.org/wiki/Q29094452"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/henn-albert-w-mansion-00000422/"}
