It began as an officers' quarters of an 1838 military garrison and was enlarged in the 1890s.","why_significant":"On September 14, 1901, Theodore Roosevelt took the presidential oath of office in the library of this house, following President McKinley's death after the Pan-American Exposition shooting. It is one of few inaugural sites outside Washington. It is also one of the oldest houses in Buffalo, with local historical and architectural importance.","narrative":"Located on Delaware Avenue in Buffalo, this two-and-a-half-story brick house began as an officers' quarters at a military garrison built in 1838. After the post was abandoned in 1845, the building passed into private hands. Albert Lanning moved its portico to the Delaware Avenue side in 1863. In the 1890s lawyer Ansley Wilcox hired Buffalo architect George Cary to roughly triple its size, producing a stately Greek Revival mansion. On September 14, 1901, Theodore Roosevelt was sworn in as the twenty-sixth President in the house's library, in front of McKinley's Cabinet members, after President McKinley died following his shooting at the Pan-American Exposition. Roosevelt was a close friend of Wilcox. The house later served as a restaurant before local citizens saved it from demolition in the 1960s. Restored from 1970, it now includes a museum on the first floor and is among the few inaugural sites outside Washington.","period_of_significance":"1900-","architect_builder":"U.S. Army/George Cary","architectural_style":"Greek Revival","criteria":[],"status_note":"Restored beginning in 1970; the front first floor operates as a historic house museum with visitor reception and exhibit space, and the rear portion is leased as an office.
