Former Formula 1 driver Tony Brooks, one of the defining figures of the racing series in the 1950s, has died.

The former racing driver died at the age of 90, British media reported, citing his daughter. “He was part of a special group of drivers who were pioneers and pushed the boundaries at a time when the stakes were high,” Formula One managing director Stefano Domenicali said.

Brooks, a Briton, won six Formula One races, including Germany in 1958 and 1959. In 1959, he narrowly missed winning the World Championship title in a Ferrari.

Because of his studies in dentistry, Brooks was also known as the “racing dentist”. However, he gave up his medical career for his Formula 1 career. At the age of only 29, Brooks retired from motorsport in 1961 after 38 Formula 1 starts. He was last regarded as the last living Grand Prix winner of the 1950s.
