Here is a neat video package from WKYC that profiles Molded Fiberglass Companies based in Ashtabula, Ohio. MFG was founded in 1948 by Robert Morrison who initially was using glass reinforced plastic to make shelves for Wonder Bread. Morrison recognized the many benefits of fiberglass and made several attempts to convince GM that it was suitable for automotive bodies. In 1953 following the introduction of the Corvette at the Motorama show in New York City, GM gave MFG the contract to build the bodies for the Corvette.
I’d like to point out one error in this story. They said Ford was introducing the Thunderbird and GM needed to play catchup with the Corvette. It was actually the other way around. A small error, but an important one because Corvette sales were lackluster in the first years and the car was nearly canceled except GM didn’t want to ceede the sports car market to Ford’s rival two-seater.
To read more about Robert Morrison and Molded Fiberglass Companies contribution to Corvettes, I highly recommend reading Randy Leffingwell’s Corvette Fifty Years which details the meetings between MFG and GM. The book is available at Amazon.
