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.
Ezra Greenleaf Weld
Of the six daguerreotypes of Douglass that have survived, only one besides Greenleaf's image has had its daguerreotypist identified. Greenleaf's image is unique because it is a group shot at an outdoor meeting rather than a studio portrait. Daguerreotypes were seldom attempted under these circumstances because the long exposure time required made it difficult to get a satisfactory result. Weld's is the only daguerreotype of Douglass whose date is known with certainty. This daguerreotype is also unique in the paradoxical sense that it is the only one known to have been copied. Two original half-plates exist: One is held by the Madison County Historical Society in Oneida, New York, the other is in a private collection and currently on display at the Smithsonian Institution in Washington, D.C. The copy (shown above) is in the J. Paul Getty Museum, Los Angeles, California.
