Ayres and Ayres records represents extensive documentation of a prominent San Antonio firm spanning a period of 83 years of practice (1894-1977). Atlee Bernard Ayres (1872-1969) and his son Robert Moss Ayres (1898-1977) formed a partnership in 1925. Papers, photographs, and drawings document the long practice of the San Antonio architects. The firm library was donated to the Architecture and Planning Library Special Collections.
