July 16th 1955
Stirling Moss won his first Grand Prix race, the British Grand Prix in Aintree, driving a Mercedes Benz W196. Moss is considered the greatest racer that never won a World Driving Championship, having finished second to Juan Manuel Fangio for four consecutive years. Most impressive is Moss' record of having won 16 of 66 Grand Prix starts and 194 of his 466 starts in major events.
