Dan Gurney, born on this day in 1931, was often at the forefront of innovation during his outstanding career in motorsport, blazing multiple trails in various areas.
The famous 'Gurney flap' – a small lip placed at the trailing edge of a wing to generate more downforce while producing minimal drag – is still exploited by aerodynamicists in both the racing and aeronautic industry.
But among Gurney's other pioneering initiatives was the adoption of the Bell Star full-face helmet first used by the American driver in F1 in 1968 and which was widely adopted by drivers thereafter.
In this picture - taken by a 14-year-old Paul-Henri Cahier by the way - Dan is at the wheel of his Eagle T1G, sitting on the grid of the 1968 German Grand Prix at the daunting Nürburgring, waiting to race off into the 14-mile Green Hell in torrential rain.
Oh, and by the way, for all the protection offered by Bell's new lid, seatbelts in F1 were still not mandatory back then!
