After Nick Ut's brother, an Associated Press photographer, was killed in Vietnam, he convinced AP to let him work in the darkroom, where he would cry over the photographs he printed. He spent long days in the darkroom before he could eventually take his own pictures. In 1973, Mr. Ut won a Pulitzer Prize for spot news for his photograph "The Terror of War," which depicts children in flight from a napalm bombing. Mr. Ut currently works for the Associated Press in Los Angeles.
