1856 Address Unknown, Dundee, New York.
Mr. Letts appeared in one announcement on August 6, 1856 in the Penn Yan Democrat (Penn-Yan, New York). A New Picture.—We were recently shown by Mr. Letts, of Dundee, an entirely new process of taking Daguerreotypes, of his own invention. The pictures are taken on paper, and closely resemble very fine oil paintings, the natural color of the hair, face, clothing, &c., being accurately preserved.—We are informed that the coloring, &c., is all done at one process, and in less time than is required to take the ordinary daguerreotype. This is doubtless one of the greatest improvements in the art yet discovered, and we hope that the highest expectations of the inventor, who is a practical Chemist and Daguerrean artist, may be realized. We understand that he has already secured a patent for his invention.
The is possibly the same J. M. Lett listed in Craig’s Daguerreian Registry as being active in Dundee, New York in 1859.
