Clay Regazzoni
The team's first win came when Clay Regazzoni drove the Cosworth-powered Williams FW07 to victory at the 1979 British Grand Prix at Silverstone. Their first Drivers' Championship and Constructors' Championship both came in 1980, with the Australian Alan Jones winning the drivers' title. Between 1981 and 1997, the team won six more drivers' championships and eight more constructors' championships.
