David Robertson, the man who helped get Kimi Raikkonen and Jenson Button in to Formula 1, has died. He was 70.
Working as a driver manager with his son Steve, Robertson proved to be astute in both finding young talent and sealing deals that got them quickly in to F1.
Having helped push Button up the junior ranks to secure his debut with Williams in 2000, Robertson was even more impressive a year later in convincing Sauber - and the FIA - to allow Raikkonen to race in F1 despite only having competed in Formula Renault previously.
Although Button would eventually move on to different management, Robertson continued to look after Raikkonen's career.
As well as managing drivers, Robertson also helped set up the successful Formula 3 team Double R Racing,
Button himself expressed his sadness at the passing of Robertson, who had been ill for some time.
"Very sad to hear that David Robertson who helped me reach my dream of racing in Formula 1 has passed away," wrote Button on Twitter. "My thoughts are with his family."
