"Rings of Fire is the story of how Edwin Land, founder of Polaroid, and a unique cast of characters created the calcite-based optical ring sights that helped U.S. naval antiaircraft guns and army bazookas zero in on targets and claim victory in World War II. It is a story of American ingenuity, determination, and grit in the face of enemy attacks"-- Provided by publisher.
