Civil War Photos

As a Master Ranger Corps volunteer at Antietam National Battlefield, I was delighted to learn that Princeton’s collections encompass one of the few copies of Alexander Gardner’s Sketch Book, plus photographs contributed by Gen. George McClellan’s namesake and only son (feature, March 19). Mathew Brady’s New York exhibit of the extraordinary Antietam images taken by Gardner (and James F. Gibson) is arguably where modern photojournalism began.

One correction to this fine article: The battlefield is 64 miles (not 25) from Washington, D.C., as a quick check with Professor Emeritus James McPherson, a welcome and frequent visitor to Sharpsburg, Md., would have revealed.
