William G. Tachau

William Gabriel Tachau, AIA, (April 1875 – January 1969 ), was an American architect active in early- to mid-twentieth-century New York City. With Lewis Pilcher, he was a partner in the architectural firm of Pilcher & Tachau from 1904 to 1919 when he established the firm of Tachau & Vought.
