I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
George Norman Barnard (December 23, 1819 – February 4, 1902) was an American photographer who was one of the first to use daguerreotype, the first commercially available form of photography, in the United States. A fire in 1853 destroyed the grain elevators in Oswego, New York, an event Barnard photographed. Historians consider these some of the first "news" photographs. Barnard also photographed Abraham Lincoln's 1861 inauguration. Barnard is best known for American Civil War era photos. He was the official army photographer for the Military Division of the Mississippi commanded by Union general William T. Sherman; his 1866 book, Photographic Views of Sherman's Campaign, showed the devastation of the war. This photograph, by Mathew Brady, shows Barnard c. 1865.Photograph credit: Mathew Brady; restored by Adam Cuerden
