Daguerreotype
Morse met the inventor of the daguerreotype, Louis-Jacques-Mande Daguerre, in Paris in January 1839 when Daguerre's invention was announced [2]. While the daguerreotype fascinated Morse, he was concerned about how the new invention would compete with his telegraph. However, Morse's viewing of the daguerreotype alleviated his fears when he saw how revolutionary its technology was. Morse wrote a letter to his brother Sidney describing Daguerre's invention, which Sidney then published in the New-York Observer on April 20, 1839. While this was not the first report of the daguerreotype to appear in America, it was the first in-person report to appear in the United States.
Alphonse Giroux
Giroux is also known for constructing the daguerreotype cameras designed by Daguerre, the first commercially manufactured photographic camera in the world.
A mass-produced daugerrotype camera cabinet manufactured by Giroux, who was the brother-in-law of Louis Daguerre, was exhibited at the 1839 Exposition des produits de l'industrie française in Paris. It did not win an award, although Giroux did gain a silver medal for a jewelry box.
