Allis, who left a deep and beneficial impress upon the architecture of southeastern Connecticut. It is exceedingly difficult to draw a sharp line of distinction between the carpenter-architects and the earliest representatives of the professionally trained architects whose occupation consisted mainly in designing buildings and supervising their erection. During the greater part of the eighteenth century, the many able amateur architects and the capacity of the carpenter-architects to translate and embody acceptably in tangible form the conceptions supplied by their employers would naturally militate against the success of a numerous class of men whose sole occupation was to design and supervise. It is not at all improbable, therefore, that some of the men, whom we should be disposed to regard as the early representatives of the professional architect class, judging from the importance and visible evidence of the structures attributed to them, played the rôle of contractors as well for the erection of the buildings they designed, even though they did not share in the manual labour. We know, for example, that Richard Munday first appears in active career as the partner of one Wyatt in a building or contracting business. His capacity, however, shown by the Town House or State House in Newport, built from his plans in 1743, entitles him to a high rank among early American architects. While some of the early professional architects--the term is not altogether felicitous but seems necessary for the sake of differentiating them from the other two classes--were doubtless self-trained to a great degree, a few appear to have had instruction in England under competent masters. Notable among them was Peter Harrison, the architect of the Market or City Hall of Newport, built in 1760, who was sometime an assistant to Sir John Vanbrugh and is said to have been a pupil of James Gibbs. McBean, the designer of St. Paul’s Chapel of Trinity Parish, New York, erected in 1764, is also thought by some to have been a pupil of Gibbs, although there seems to be no trustworthy base for such a supposition.
