Almost 100 years old now, photojournalist Ruth Gruber has worn many hats throughout her extraordinary career. Writer, lecturer and once the youngest Ph.D in the world, Ruth took on a dangerous secret mission for the Roosevelt administration during the Nazi Germany period and photographed Holocaust refugees. A documentary of her life, 'Ahead of Time,' airs on Showtime this evening. See a selection of her images and check out Ann Curry's fascinating interview with Ruth, below.
