Davis, Alexander Jackson, 1803–92, American architect, b. New York City. He was the partner of Ithiel Town of New Haven, with whom he designed many important buildings in both the Greek and Gothic revival styles. Works by him include the New York Customs House (1832), now the Subtreasury; the state capitols of Indiana (1832–35), North Carolina (1831, in association with David Paton), Illinois (1837), and Ohio (1839); and a number of villas along the Hudson River, including Lyndhurst (1838–42). The most prolific practitioner of his time, Davis also anticipated, in a New York shop front designed in 1835, the architectural use of iron.
