About Keith Duckworth
David Keith Duckworth was an English mechanical engineer. He is most famous for designing the Cosworth DFV engine, an engine that revolutionised the sport of Formula One. After only three years with Lotus, Duckworth, along with fellow Lotus employee Mike Costin, founded Cosworth, a racing engine design and development firm, in 1958. Costin was obliged to remain with Lotus, having recently signed a restrictive contract; for the first few years Duckworth worked essentially alone at Cosworth until Mike could join him. Duckworth claimed that allergy to medication he was receiving caused his flying problem - in civilian life he became a keen light aircraft and helicopter pilot.
