James Nachtwey is an influential American photojournalist and war photographer.
Nachtwey grew up in Massachusetts, graduated from Leominster High School and attended Dartmouth College from 1966 - 1970. Influenced by imagery from the Vietnam War and the American Civil Rights movement, he taught himself photography.
During his coverage of the United States invasion of Iraq, he received his first combat injury. As Nachtwey, along with “Time” correspondent Michael Weisskopf rode in the back of a humvee with the United States Army Tomb Raiders, an insurgent threw a grenade into the vehicle. Weisskopf grabbed the grenade to throw it out of the humvee, but it exploded in his hand. Nachtwey managed to take several photographs of medic Billie Grimes treating Weisskopf before passing out.
