an American portrait painter in Massachusetts and New York. He began as a chaise painter in his father's chaise manufactory. In the Boston area, he was a student of Gilbert Stuart. He painted a number of likenesses in Salem, including the wealthy merchant Elias Hasket Derby. Frothingham would have been a regional competitor to the younger Chester Harding (1792–1866), but in 1826 moved to Brooklyn in New York City. In 1828 he was elected into the National Academy of Design as an Associate member, and became a full Academician in 1831.
