Mathew Brady (1822-1896) was a photographer whose work is quite well known and famous today. In addition to taking photographs of 19th century politicians, who we would otherwise have no images of except paintings, he also documented the American Civil War in photographs. In fact, the Civil War is the first war to be documented and disseminated to the public via newspapers using photographic accompaniment. The vast majority of those photos were taken by Mathew Brady or one of his many, personally trained assistants.
He and his assistants marched out across the country during a very dangerous time for travel, in search of the most compelling, truthful images of the war. Amongst them, they took more than ten thousand photographs of the war, letting the average civilian American see in real, graphic detail just what was happening to the men on the battlefields of the nation.
