One of the most celebrated war photographers and often referred to as the father of photojournalism, Mathew Brady will be always remembered in the journalism arena for documenting the American Civil War on a grand scale. In 1862, he was admired for presenting some heart-wrenching photographs of the “Battle of Antietam” in an exhibition. It is a matter of fact that this legendary photographer went bankrupt during his last days and died penniless in the charity ward of a hospital in New York.

Globally admired for depicting the actual face of Vietnam War, Philip Jones-Griffiths is also known for being an unparalleled journalist and a great humanitarian.

During World War I, Kirtland was based in France as a correspondent for Leslie's Illustrated Weekly. As an acknowledged journalist, she competed with her male counterparts, seeking out action.

Adams served as a correspondent for Harper's Magazine in Europe during World War I. She was the only female correspondent permitted to visit the trenches.

In a 45-year career, much of it spent in the front ranks of news photographers, he worked for The Associated Press, Time and Parade, covering 13 wars and amassing about 500 photojournalism awards. But it was a 1968 photograph from Vietnam, taken for The A.P., that cemented his reputation in the public eye and among his peers. That black-and-white image captured the exact moment that Brig. Gen. Nguyen Ngoc Loan, then serving as the national police chief of South Vietnam, fired a bullet at the head of a Vietcong prisoner standing an arm's length away on a Saigon street.
