Gendron, of 13 Tremont Row, Boston
In the mid- to late 1800s Tremont Row in Boston had become a centre for the artists in the city, with many portrait painters, sculptors, engravers, and of course photographers, including J.J. Hawes, who was one of the early daguerrotypists. 13 Tremont Row had been occupied by a photographic studio since at least 1860, when ambrotypist Robert J. Chute worked from premises at that address. Before that, however, composer William H. Oakes and portrait painter Charles Hubbard had lived there. Gendron presumably moved there in the latter part of the century, and appears not to have lasted long.
