Acclaimed photographer David Hume Kennerly will discuss photography during times of crisis and upheaval Wednesday on May 1 at noon at the Fowler Museum. In 1972 Kennerly won the Pulitzer Prize for Feature Photography for his work documenting wars in Vietnam, Cambodia and the area along the India-Pakistan border. Since then, he has captured historic moments around the world, from iconic war images to behind-the-scenes glimpses of American presidents. The program is free and open to the public.
