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.
Daguerreotype
In 1829 French artist and chemist Louis-Jacques-Mandé Daguerre, when obtaining a camera obscura for his work on theatrical scene painting from the optician Chevalier, was put into contact with Nicéphore Niépce, who had already managed to make a record of an image from a camera obscura using the process he invented: heliography.
