Its interior trim is in an outstanding state of preservation. It is also tied to Marcus Bossler, a wealthy Dayton contractor and quarry operator.","narrative":"Built around 1869, this Second Empire mansion of brick at 136 South Dutoit Street sits on a hill above Dayton, Ohio. A limestone retaining wall, stone pillars and a wrought iron fence mark the corner lot. The six-bay facade has a projecting central pavilion, rusticated quoins, bracketed window pediments and a richly decorated arched entrance. A patterned slate French roof with pedimental dormers and a convex mansard crowns the front. Inside, a center hall holds a curved, divided staircase, and heavy woodwork, fruit-pattern plaster ceiling moulding and frosted glass transoms survive. The house was built for Marcus Bossler, born in Pennsylvania in 1815, who came to Dayton in 1842 and became a stonemason, contractor and operator of limestone quarries that supplied stone for many local buildings, including the county jail. His business failed by the late 1870s and he sold the house to satisfy creditors. Long divided into apartments, the house was being rehabilitated as a residence and restaurant when listed.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Second Empire","criteria":[],"status_note":"Divided into bachelor apartments for many years but well maintained; the owner was converting it to a residence and restaurant, with rehabilitation in progress at the time of the form.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.174172-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80003170.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003170/eaafc36588-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003170/eaafc36588-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Marcus_Bossler_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Marcus_Bossler_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71990444","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138634080"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/montgomery-county/bossler-marcus-house-80003170/"}
