It was designed in 1900 by local architect George P. Stauduhar and built from 1902 to 1904 for Robert and Thekla Wagner.","why_significant":"It is locally significant under Criterion C as a representative and well-preserved example of Classical Revival residential architecture. It is also one of Stauduhar's most complete uses of classical motifs. Its history is tied to Robert Wagner, a brewery head and banker, though significance under Criterion B is not claimed.","narrative":"This two-story frame house at 904 23rd Street in Rock Island, Illinois, was designed in 1900 by local architect George P. Stauduhar and built between 1902 and 1904 for brewer Robert Wagner and his wife, Thekla. It sits on a rusticated limestone foundation and is faced with narrow clapboards. A two-story pedimented portico with paired Ionic columns marks the entrance, flanked by balustraded porches and a porte cochere. Inside, the original plan survives, with oak paneling, leaded glass bookcases, a hand-painted parlor frieze dated 1904, and a speaking tube system. A one-car garage at the rear also contributes. The house is significant for its architecture. Stauduhar often used classical details, but nowhere as fully as here, and the result is a clear example of Classical Revival residential design. Wagner led the Rock Island Brewing Company and later held major roles in local banks. The Wagners lived in the house until their deaths in 1937 and 1956.","period_of_significance":"1904","architect_builder":"Stauduhar, George P.","architectural_style":"Classical Revival","criteria":["C"],"status_note":"Owner-occupied single dwelling with minor alterations; the original floor plan and many interior features are retained.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.641259-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/57/8939/28893957/content/electronic-records/rg-079/NPS_IL/90000721.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000721/91280d58e3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000721/91280d58e3-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Wagner_House_RI_IL.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Wagner_House_RI_IL.jpg"},"district":{"nrhp_refnum":"98001046","name":"Broadway Historic District","url":"https://nationalhistoricalregister.com/districts/illinois/broadway-historic-district-98001046/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893957","wikipedia":"https://en.wikipedia.org/wiki/Robert_Wagner_House","wikidata":"https://www.wikidata.org/wiki/Q7350782"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/rock-island-county/wagner-robert-house-90000721/"}
