1950 saw the Swiss Grand Prix being inducted as part of the new Formula One World Championship (although at the time, all the races were run in Europe except the Indianapolis 500, but this race was not run to F1 regulations). This race was won by Italian Nino Farina, who would go on to be the first Formula One world champion. 1951 saw Argentine Juan Manuel Fangio dominate in his Alfa after taking advantage of Farina's wrong decision not to make a pit stop to change tyres during changing wet-to-dry conditions. 1952 saw Briton up-and-comer Stirling Moss run as high as third in his underfunded Alta-powered HWM, and Italian Piero Taruffi scored his first and only F1 victory; it was also the only championship race (other than the Indianapolis 500) not won that year by his Ferrari teammate and countryman Alberto Ascari. Pre-war great and three-time Swiss GP winner Rudolf Caracciola was competing in a support sportscar race and crashed into a tree, and the violent accident that ensued ended up breaking one of his legs, which effectively ended his long racing career. 1953 saw Ascari battling back after a pit stop to fix the misfiring engine in his Ferrari; he came back out in fourth and stormed round the circuit, passed Fangio in a Maserati, his teammates Farina and Mike Hawthorn to take victory. Ascari also won his second Drivers' Championship at that event. 1954 saw Fangio (now driving a Mercedes) lead from start to finish in rainy weather and he took his second Drivers' Championship from countryman José Froilán González.
