Zusätzliche Infos über Mathew Brady.

Brady can be viewed as the father of photojournalism. He was the most prominent photographer of the Civil War because of his commitment and mastery of his job. He mastered the art when he was in his 20s and spent his own money to take pictures of the war. In 1844, Brady opened a private studio in New York City displaying photographs of famous Americans. He himself said "From the first, I regarded myself as under obligation to my country to preserve the faces of its historic men and mothers".

At the beginning of the war in 1861, he organized his employees into groups to spread themselves apart across the country and to get to work. Brady provided carriages called darkrooms to all his parties at his own personal expense. The total cost was about $100,000. The First Battle of Bull Run provided the first opportunity to photograph an engagement between opposing armies. Brady was very calm during a battle as we can see from Lt. J. A. Gardner's notes:

On July 21, 1861, Brady, the photographer, drove his light wagon out to the entrenchments. Approaching Captain Cooper, Brady politely asked if he could take a picture of the battery when just about to fire. The enemy, observing the movement of the preparations, began firing. Brady, seeing his camera was uninjured, recalled his assistant and took more pictures from a little to the rear.

Most people do not know that he recorded more than just photographs. Commentaries found in his traveling journal are used by historians to study the war in more detail. To illustrate the importance of his good record keeping we can point to an important occurrence in one of the battles that would have been lost if Brady did not record it. The night before a battle serene silence was all of a sudden broken when a Confederate soldier across the field began singing patriotic songs. Soon a second voice was heard, and a third, and a fourth soon both armies sang together in a spirit of common fellowship. Esprit de corps was so high that one is left to wonder how could they battle those same men come morning.

After the war Brady went bankrupt and was forced to live off his friends' generosity. The government bought his collection of 5,712 plates for $25,000 rather than the $125,000 he asked. He once said that long after his death his work will be appreciated. He was right. Some feel that Brady was as much a hero as the soldiers who fought. He died in 1896 in poverty and isolation.
