I'm very dissapointed to see that everyone has forgotten Patrick Depailler.
Considering only a handful of us were alive in 1980, and likely none of us followed F1 racing at that time...I don't think he's forgotten as much as he was just part of another generation of drivers and fans of Grand Prix racing.
Depailler wasn't much of a qualifier, but he'd turn up the wick when the racing began. He took chances with motorcycles, handgliders, even bicycles when he wasn't driving a racing car; unfortunately, his antics nearly cost him his life in 1979, but put him out of racing car until the following year, but with Alfa Romeo. Teams were getting a bit more professional in their attitude towards their drivers' activities when away from an F1 car. It's a pity, because Grand Prix drivers used to drive sports cars, production-based cars, or other specials on the off-F1 race weekends...but this age was coming to an end by the mid-1980s anyhow, with increasing contract demands.
There's many pics of Patrick getting the Tyrrell, Ligier, and Alfa Romeo sideways; he was quite careful in most of his cars, but with the exception of the 1979 Ligier JS9, he never had a 100%-competitive F1 seat. The Tyrrells were good, but not great cars after many aerodynamic changes were made after 1973 season, and the Alfa Romeo team began it's first full year of racind when Depailler came aboard.
But that Ligier, although not quite the budget of the Ferrari and the Renault of the time, and not quite the ground-effect superiority of the Lotus and the Williams of the time, was a surprise as it was quick right out of the box. The first two races were claimed by Ligier, and by the end of the third race, the French outfit was still leading the Contructor's Cup. It's hard to tell what happened; the other teams played catch-up, Ligier lost the wind form their sails after the Monaco round (Depailler's handgliding accident), or the team didn't perform the constant development work to keep up with the big boys. In any case, it was really a case of many opportunites lost.
Depaillier's first win didn't arrive unti the 1978 Monaco GP, and he was driving the 4-wheel Tyrrell, having shaken off the P34 at the end of last year, since it was at the end of it's developmental life. His second, and last win was the 1979 Spanish GP, held at a notorious Jarama circuit which was very much like the Hungaroring; you could only pass predictably in one place...the end of the start-finish straight!
Anyhow, he's another fellow, like Gilles Villeneuve, that I'd wish I'd been able to see him race live...
