One of McLaren's founding fathers, Tyler Alexander, died aged 75 on Thursday.
Alexander founded the Formula One team alongside Bruce McLaren in 1963 and was involved for more than 40 years in various capacities in two different spells before retiring on the eve of the 2009 season.
The American, who helped McLaren to five consecutive championships between 1967 and 1971, originally left the British manufacturer in 1983 though he returned six years later.
"On behalf of all at McLaren, I'd like to pay heartfelt tribute to one of our team's founding fathers, and to offer our deepest condolences to his many friends and his ever-loving companion, Jane Nottage, who has always stood by him, valiant to the very end," said McLaren chairman and CEO Ron Dennis, who lured Alexander back to the team in 1989.
"Alongside Bruce McLaren, who founded the McLaren company in 1963, Tyler Alexander was one of the first pillars of our company - working hard alongside Bruce from the very earliest days - and Bruce couldn't have asked for a sturdier pair of shoulders upon which to help build the team's reputation.
"Tyler lived and breathed McLaren and, following his retirement in late 2008, during which season he attended every Grand Prix and played an important part in securing the team's and Lewis Hamilton's world championship success, he remained a much loved and greatly valued chum to many of us, regularly visiting our Woking factory to catch up with pals old and new. Tyler's was a friendship that you could really rely upon; he was a man who would never let you down."
