Robert Cornelius, a young manufacturer of lamps, quickly learned the basics of the daguerreian process and began to produce imagery.
Cornelius' background had given him a practical knowledge of metallurgy and chemistry and his discovery that bromine was a successful reagent in the process permitted him to open a commercial photographic studio - only the second such establishment in America.
Charles John Biddle (1819-1873) a native of Philadelphia, graduated from Princeton in 1837, where he studied law, and was admitted to the bar in 1840 (at around the time this portrait was made). He later served in the Mexican-American War, where he was commended for gallantry (see Christie's, New York, October 8, 2008, lot 522, for another, later portrait of Biddle by Cornelius.)
