It was later the home of the surgeon Philip Syng Physick.","why_significant":"The house is noted for its doorway with fan light and side lights and for its largely intact interiors, which represent late eighteenth-century American architecture. Its association with Philip Syng Physick, a leading surgeon of the early American medical profession, adds to its importance.","narrative":"Built about 1786 at 321 South Fourth Street in Philadelphia by Henry Hill, a merchant who had been a justice of the peace and served in the Pennsylvania Assembly and Executive Council. The three-story brick house with an attic has a shingled hip roof, four dormer windows, and a marble-tiled entry hall with a mahogany staircase. Its doorway with fan light and slender side lights is singled out as especially fine. After Hill's death in 1798, the house passed to Dr. Philip Syng Physick, often called the Father of American Surgery, who was known for his surgical instruments and for treating yellow fever patients in 1793. Physick's family kept the house until 1965, when it was sold to the Philadelphia Society for the Preservation of Landmarks. It was restored to its appearance around 1810, and nearly all of its interiors survive intact. The house is significant as an example of late eighteenth-century American architecture and as the home of a major early medical figure.","period_of_significance":"ca. 1786","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Restored 1966-68 for the Philadelphia Society for the Preservation of Landmarks; the coach house was razed due to structural deterioration.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.919522-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/71000726.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/71000726/52ffd672d0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/71000726/52ffd672d0-1600.webp","licence":"CC BY-SA 4.0","author":"Beyond My Ken","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hill-Physick-Keith_House.jpg\" rel=\"noopener\">Beyond My Ken</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hill-Physick-Keith_House.jpg"},"district":{"nrhp_refnum":"71000065","name":"Society Hill Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/society-hill-historic-district-71000065/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997386","wikipedia":"https://en.wikipedia.org/wiki/Hill%E2%80%93Physick%E2%80%93Keith_House","wikidata":"https://www.wikidata.org/wiki/Q15224026"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/hill-physick-house-71000726/"}
