Bass Otis (July 17, 1784 - November 3, 1861), was an early American artist, inventor, and portrait painter.
Otis then moved to New York City, perhaps working as an assistant to painter John Wesley Jarvis.
One of Otis's most famous early works showed a scene inside a metalworking shop, probably a reflection of his years as an apprentice.
Some of the remaining portraits were exhibited in Delaplaine’s Philadelphia gallery, which became part of Rubens Peale's New York museum.
Other well-known sitters included author James Fenimore Cooper, Thomas Garrett, and U.S. President William Henry Harrison.
