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
In the US and Britain, the tradition of preserving miniature paintings in a wooden case covered with leather or paper stamped with a relief pattern continued through to the daguerreotype. Some daguerreotypists were portrait artists who also offered miniature portraits. Black-lacquered cases ornamented with inset mother of pearl were sometimes used. The more substantial Union case was made from a mixture of colored sawdust and shellac (the main component of wood varnish) formed in a heated mold to produce a decorative sculptural relief. The word "Union" referred to the sawdust and varnish mixture—the manufacture of Union cases began in 1856. In all types of cases, the inside of the cover was lined with velvet or plush or satin to provide a dark surface to reflect into the plate for viewing and to protect the cover glass. Some cases, however, held two daguerreotypes opposite each other. The cased images could be set out on a table or displayed on a mantelpiece. Most cases were small and lightweight enough to easily carry in a pocket, although that was not normally done. The other approach, common in France and the rest of continental Europe, was to hang the daguerreotype on the wall in a frame, either simple or elaborate.
