Leonard Pelham Lee (1903–1980) was an executive in the English internal combustion engine industry.
He lived at Park House, Warwick Road, Coventry, and was appointed the Chairman of British Internal Combustion Engine Manufacturers Association in 1960 at age 57.
In 1961, Coventry Climax was dominating the British Formula One field with the successful FPF and FWMV engines, but FWMV's initial selling price (3,000 Pounds), though considerably higher than the selling price of FPF (2,250 Pounds), did not cover the development cost and the mounting maintenance cost as more and more teams wanted to run it.
In May 1964, the Royal Automobile Club presented the Dewar Trophy, which is given at the recommendation of RAC's Technical and Engineering Committee for the most outstanding British achievement in the automotive field, to Leonard Pelham Lee.
The last time Dewar Trophy was awarded before 1964, the recipient was Alec Issigonis for British Motor Corporation in 1959, who once was a Junior Engineer at Coventry Climax, on the design and production of ADO15 Mini.
