Klauer Optical, Dubuque

Shortly after brothers Eldon and Clarence Klauer co-founded Klauer Optical in 1939, they found themselves making binocular lenses for the United States Navy during World War II. Today, the company's work orders have changed, but the Klauer name remains. Clarence's grandson Jeff oversees the operation, and Eldon's son Charles fabricates the store's eyeglasses and sunglasses.
