He first appeared as a daguerreian in Hartford, Conn., in 1845, in partnership as Cary and Sage (H.R.), under Union Hall. Cary was noted as boarding at the American Hotel. His first ad in business directory reads "pictures of any kind taken in any kind of weather. Instructions given in the art...and all kinds of daguerreotype apparatus and materials furnished at short notice."
In 1846 he was listed as a daguerreian at 146 Main St., Hartford, in partnership as Cary and Stancliff (J.W.). An alternate source listed him at 158 Main St., over Olmstead & Co. Another source placed him in partnership as Broadbent (S.) and Cary in Hartford at this time. There is no listing for the partnership, although Broadbent was listed in Hartford in this year as an "artist", without a business address, and the pair subsequently operated in partnership elsewhere.
In January, 1847, Cary was noted as a daguerreian at (T.T.) Wilmot's studio, with Samuel Broadbent, in Savannah, Ga. This may be the same time as the "winter of 1848", when this partnership is substantiated by another source.
In February, 1848, Cary advertised as a daguerreian in Macon, Ga. In May of that year he advertised in Athens, Ga., and in 1849-1850 he was listed as a daguerreian in Baltimore, Md., again in partnership as Broadbent and Cary.
In 1850, between February and June, he opened and closed a gallery at Bryan Street and Market Square, Savannah, Ga. In July, 1850, he opened a gallery in New York City, at 187 Broadway. He closed that gallery in January, 1851.
In 1851 he was listed as a daguerreian in Charleston, S.C., as well as in Savannah, Georgia, in partnership as Perkins (J.W.) and Cary, at the corner of Bryan Street and Market Square.
He spent the summer of 1852 in Bridgeport, Conn. Whether or not he operated as a daguerreian there is unknown.
In 1853, Cary reportedly bought a daguerreian establishment in New York City; he left Perkins in charge of the Savannah gallery. The same source noted that Cary was formerly of Broadbent and Cary of Hartford, Conn.
In December, 1854, it was noted in Humphrey's Journal that Cary and Perkins had just opened rooms in Macon, Georgia, in conjunction with their old rooms, and that Cary had just left New York City to spend the winter in Savannah.
In 1854-1855, Cary was listed as a daguerreian at 407 Broadway, New York City, in partnership as Cary and Perkins (A.J.) [I believe this is a directory error, and should be J.W. Perkins]. Cary was not listed in the individual directory. In 1856 he was listed in partnership with B.F Powelson (Powelson may have previously been in Buffalo, N.Y.)
From 1858 to 1860, Cary was noted in Savannah, Ga. In 1858 he was listed as the proprietor of a daguerreotype gallery at 1 Market Square, upstairs. In 1859 he was listed as a daguerreian at 159 Broughton Street, in partnership with Malambre, an artist; and White, a photographer. In 1860 he was listed as a daguerreian at 147 Congress St., Savannah, and boarded at the Marshall House.
