This is an excellent interview with Gordon Buehrig from back in 1989 carried out as part of the Automotive Oral History Project.
Some of the cars designed by Gordon Buehrig were the Stutz Black Hawk, Auburn 851 Boattail Speedster, Duesenberg J, Duesenberg J, 1956 Lincoln Continental Mark II, and, perhaps the car he’s most known for, the Cord 810/812. He also invented the removable T-top, patented in 1951
I’ve actually visited the excellent ACD Museum in Auburn Indiana and there is a display of Buehrig artefacts.
