Knox Building, 1944.

Designed by architect John H. Duncan, who also created the Grand Army Plaza Memorial Arch and the General Grant National Memorial, the Knox Building was constructed in 1901 and 1902. The 10-story Beaux-Arts structure was the headquarters for the Knox Hat Company (founded in 1838). The Beaux-Arts style for a commercial building was unique even in a city dotted by buildings of this style, most of which were residences, hotels, and civic buildings. In 1965 the building became the headquarters for the Republic National Bank and in 1985 work was undertaken to construct a 29-story L-shaped tower that hugged the 1902 building. The new construction unfortunately meant the demise of the neighboring Art Deco Kress building. Today the Knox mansard remains a striking visual on the corner, with the HSBC Tower as its modern backdrop.
