Inside Bob Pond's car collection

Robert Pond was an industrialist, an aviator, a Navy pilot, an aircraft designer, a genuine car enthusiast, a philanthropist, a Minnesotan at heart and a man who turned a family business from eight employees to a global $100-million concern. Pond was born in 1924 in Edina, Minn., 10 miles southwest of Minneapolis. He signed up for the Navy Air Corps in 1942, and survived three years of training on J-3 Piper Cubs and PBY Catalinas to graduate in July of 1945 -- just three months before Japan surrendered to the US.
