Photography in the United States
In spring 1839, the daguerreotype was introduced into the United States by an Englishman named D.W. Seager, who took the first photograph of a view of St. Paul’s Church and a corner of the Astor House in Lower Manhattan in New York City. Painter and inventor Samuel Finley Breese Morse had met Louis Daguerre in Paris in the spring of 1839, becoming the first American to see his photographic process and becoming enamored with it as a result. When he returned to the United States later that year, he enthusiastically promoted the daguerreotype while hailing Seager's prototypical image. Morse had painted "The Gallery of the Louvre" in 1833, and the appeal of the medium of the daguerreotype was an obvious one to him: it was a means of making faithful copies of artworks, in addition to anything else that would be still in front of the slow eye of the camera.
Daguerreotype
As the daguerreotype itself is on a relatively thin sheet of soft metal, it was easily sheared down to sizes and shapes suited for mounting into lockets, as was done with miniature paintings. Other imaginative uses of daguerreotype portraits were to mount them in watch fobs and watch cases, jewel caskets and other ornate silver or gold boxes, the handles of walking sticks, and in brooches, bracelets and other jewelry now referred to by collectors as "daguerreian jewelry". The cover glass or crystal was sealed either directly to the edges of the daguerreotype or to the opening of its receptacle and a protective hinged cover was usually provided.
