American portrait, miniature, wax sculptor b.1763-d.1814 American painter. As proprietor of a waxworks museum and travelling waxworks exhibition, he was interested in modelling in wax in his early years. While moving around his native state, he was exposed to several artistic influences, beginning with Winthrop Chandler. His earliest portraits seem to date from about 1788, when he completed Mr and Mrs Samuel Hathaway (1788; New Haven, CT, Colony Hist. Soc. Mus.). Its dark, heavy outlines, its flatness and almost geometric forms derive from Chandler. The quality of Moulthrop's paintings was extremely uneven; many of the best of the surviving body of about 50 works date from around 1800. The Rev. Thomas Robbins which depicts the sitter's direct gaze and contains more detail than the earlier portraits, shows the artist at his most accomplished. In the last years of his brief career he appears to have been influenced by William Jennys and John Durand,
