Gardner, a prominent local manufacturer. It has a T-shaped plan, a central tower and a widow's walk.","why_significant":"The nomination ties the house to Robert W. Gardner, founder of the Gardner Company, a major Quincy employer known for its governor and air compressor inventions. The Gardner family's philanthropy also shaped the city. The form adds that the house has contemporary value as an example of an old building adapted to modern uses while keeping its architectural integrity.","narrative":"Built in the 1870s at 613 Broadway in Quincy, Illinois, this T-shaped Victorian brick house was the home of Robert W. Gardner, who came to the city in 1852 as a draftsman and machinist. He patented a steam governor and an air compressor in 1860 and founded the Gardner Company in 1862, which became one of Quincy's major employers and later a nationally prominent manufacturer. The Gardner family's gifts to the community are said to total millions of dollars. The house mixes French Second Empire features, such as the central tower and tall windows, with Italian Villa elements like wide eaves, round-arch windows and brackets. Inside are a mosaic tile entry floor, a walnut staircase and carved mantels. The Gardners lived there until 1913. It later served as a boarding house, doctors' offices and apartments, and stood vacant for periods. A restoration in 1977-78 returned it to use as offices.","period_of_significance":"Ca. 1875 - 1907","architect_builder":null,"architectural_style":"Eclectic Victorian with French Second Empire and Italian Villa influences; Neo-Grec and Eastlake details","criteria":[],"status_note":"Restored November 1977 to November 1978 and in use since December 1978 as engineering offices; the attic was being renovated into an apartment.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.668234-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/97/8916/28891697/content/electronic-records/rg-079/NPS_IL/79000812.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79000812/f4b87fc1b4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79000812/f4b87fc1b4-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Quincy_Gardner_House.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Quincy_Gardner_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891697","wikipedia":"https://en.wikipedia.org/wiki/Robert_W._Gardner_House","wikidata":"https://www.wikidata.org/wiki/Q7350675"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/adams-county/gardner-robert-w-house-79000812/"}
