It is also tied to the Langdon and Pratt families, to newspaper publisher Harry S. Brooks, and to the Elmira Eagles Aerie 941. It is also listed as an Underground Railroad site.","narrative":"Elmira's Pratt House, also called the Langdon-Pratt House, is a brick Italianate residence at 413 Lake Street. It began on Union Place and was moved to Lake Street and heavily remodeled by Daniel R. Pratt, probably in 1872. The result is a picturesque building with two asymmetrical towers, a bell-cast roof with cresting, bracketed cornices and round-arched windows. Inside, cherry woodwork, elaborate fireplaces and a long stair hall reflect the wealth of its owners. Jervis Langdon, Mark Twain's father-in-law, once lived in the original house, and the nomination notes its link to the Underground Railroad through John W. Jones. Later owners included Charles R. Pratt and newspaper founder Harry S. Brooks. In 1926 the Elmira Eagles Aerie 941 bought the property and added a large tap room and lodge hall to the west. In 2007 it passed to a non-profit group planning a community arts center.","period_of_significance":"ca 1872-ca 1950","architect_builder":null,"architectural_style":"Italianate; Arts & Crafts","criteria":["B","C"],"status_note":"Ownership passed in 2007 to a non-profit arts organization for a planned community arts center; current function is listed as work in progress.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.667582-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/08001075.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/08001075/9e2f901ae0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/08001075/9e2f901ae0-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Upstate New York","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pratt_House_Oct_09.jpg\" rel=\"noopener\">Doug Kerr from Upstate New York</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pratt_House_Oct_09.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316836","wikipedia":"https://en.wikipedia.org/wiki/Pratt_House_(Elmira,_New_York)","wikidata":"https://www.wikidata.org/wiki/Q7238762"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/chemung-county/pratt-house-08001075/"}
