A. Page Brown, born Arthur Page Brown, was an American architect known for buildings that incorporated classical styles in the Beaux-Arts manner. Having first worked in the office of McKim, Mead and White in New York City in 1879, he established his own firm in 1884 and hired a young Willis Polk as a draftsman. In 1889 Brown moved his office to San Francisco, California to take advantage of the city's growth.
