Bill Biggart: The Hero Photographer Who Died Capturing 9/11

September 11, 2001, was a sunny Tuesday morning. Bill Biggart and his wife Wendy Doremus were walking their dogs in downtown Manhattan. At about 8:45 a.m., the couple noticed clouds of grey smoke forming against the clear blue New York City skyline. A passing taxi driver informed the couple that an airplane had crashed into the World Trade Center.
