Fire on Marlborough Street [1975]

From WorldsFamousPhotos.com:

On July 22, 1975, photograph Stanley J. Forman working for the Boston Herald American newspaper when a police scanner picked up an emergency: “Fire on Marlborough Street!”
Climbed atop the fire truck, Forman shot the picture of a young woman, Diana Bryant, and a very young girl, Tiare Jones when they fell helplessly. Diana Bryant was pronounced dead at the scene. The young girl lived. Despite a heroic effort, O’Neil knew he had been just seconds away from saving the lives of both.
