The Australian driver started his career in midget racing and hillclimb events, working his way up to his F1 debut at the British Grand Prix in 1955. By 1958, after a few years in Formula 2, he was a permanent fixture on the F1 grid, winning the Monaco Grand Prix the next year en route to his first world title. He won a second with Cooper the following year, but after a fruitless 1961 he returned with his own team. In 1966 he won his third and final championship, putting him on equal footing in the history books with Lauda, Piquet, Senna and Stewart, but setting him apart by one notable metric: he was and remains still the only driver to win the championship in his own car.
Sir Jack won another handful of grands prix before retiring in 1970, selling his team (which went on to win another few championships with Denny Hulme and Nelson Piquet) initially to his collaborator Ron Tauranac, who in turn sold it to Bernie Ecclestone. Several of Jack's sons and grandsons have since gone on to race professionally. Jack Brabham died peacefully on Monday at his home on Australia's Gold Coast at the age of 88.
