The American Teddy Mayer, the former McLaren Formula One boss who won titles with Emerson Fittipaldi and James Hunt in the 1970s, has died at aged 73.
McLaren team principal Ron Dennis, who succeeded Mayer after buying his shares in 1982, says Mayer was one of motor racing's few truly great men.
Mayer was a hugely competitive, if unpredictable, team boss.
Hunt once said the American had fired more champions than most others had hired but Mayer was unrepentant.
He once stated drivers are just interchangeable light bulbs, you plug them in and they do the job.
