Joseph Horatio Anderson was a British-born Colonial American architect active in Annapolis, Province of Maryland, in the late 18th century.
He designed Whitehall (1764), a plantation house in Anne Arundel County, outside Annapolis.
[3] Though Anderson boasted he was "regularly bread to those Sciences architectural design and construction & the only one upon the Continant [sic]," his octagonal design for the dome of the Maryland State House was found to be "contrary to all rules of architecture," and later replaced.
[4] In 1770, Anderson sent a letter to Rhode Island College offering his architectural services to the newly established institution.
The correspondence, however, arrived only after construction on the college's new building had already begun.
