Alexander Gardner began documenting the Civil War as one of the photographers supplying negatives to Mathew Brady, whose organization was reproducing and selling images of the conflict. These photographers were authorized by the government to accompany Union troops during the campaigns. Many of their photographs were first published and sold as prints, advertised for sale in catalogs that listed scenes of certain engagements or individuals. These naturalistic representations of the war brought to the public vivid scenes of carnage and caused a sensation at the time. In addition, periodicals represented an important market for the photographs, where artists used them as guides for the lithographs or wood engravings that illustrated journal articles.
In the book Witness to an Era: the Life and Photographs of Alexander Gardner (New York: Viking Studio Books, 1990), the writer D. Mark Katz reports that in 1863 Gardner opened his own studio in Washington, D.C., and began marketing prints in competition with Brady. In July of that year, Gardner arrived on the scene on July 5, just two days after the battle ended. Gardner's team, including the former Brady photographer Timothy H. O'Sullivan, captured vivid images of the dead soldiers still unburied. Arriving one week later, Brady missed the opportunity to photograph the bodies, however, he had access to more knowledgeable guides and thus captured images of key battle sites. In the end, the press used more of Brady's photographs than Gardner's to illustrate stories about Gettysburg.
The 1,118 images in this online collection of Civil War photographs have not been reproduced from Gardner's Sketch Book but rather from copy negatives made from other prints held by the Prints and Photographs Division. Only "Harvest of Death" (Sketch Book Plate 36) has as its source a copy negative made from a print from the book.
In the catalog (database) for this collection, the titles or "captions" provided for the photographs were developed by Library of Congress staff in the 1950's using the best historical information available and no effort was made to use Gardner's titles for
pictures that also appear in the Sketch Book. The square brackets enclosing the titles mark them as the work of Library staff.
