H. Wulff. William H. Corlett was the architect and Thomas Derry the builder.","why_significant":"The house is tied to Captain Niels Hanson Wulff, one of Napa's most important steamboat owners and masters in the late nineteenth century. It is significant in maritime history, commerce and transportation. It is one of the few surviving buildings directly linked to the city's river trade, and it remains virtually unaltered on the exterior.","narrative":"Built in 1885 at 549 Brown Street in Napa, this narrow two-story Italianate house was designed by William H. Corlett and built by Thomas Derry for steamboat captain Niels Hanson Wulff. It has horizontal board siding, a low hipped roof, elaborate eave brackets, and tall narrow windows with bas-relief pediments. A two-story bay window and a columned entrance portico shape the front. Wulff, born in Denmark in 1830, sailed schooners and later steamboats on the Napa River, and in 1889 had the sternwheeler Zinfandel built for the run to San Francisco. He lived in the house, about 120 feet from his landing dock, until his death in 1911. No wharfs or warehouses from Napa's nineteenth-century river trade survive, so the house is one of few buildings directly tied to that history. The exterior has changed little, though most interior detail was lost when the house was divided into apartments around 1980.","period_of_significance":"1885-1911","architect_builder":"Corlett, William H.
