Gerald Alden "Jerry" Wiegert (July 12, 1944 – January 15, 2021) was an American automotive engineer and businessman, notable as the founder of two companies, Vector Motors and Aquajet, and for designing the products marketed by those companies. Wiegert initially became well known in the late 1970s when he began development of The Vector, a high-performance sports car intended to be America's answer to European cars such as Ferrari, Lamborghini, and Porsche. This concept would be further developed into the Vector W8, which was manufactured and sold between 1989 and 1993.
