Joaquín Ramírez Fernández (born August 20, 1941, Mexico City) is a Mexican author and retired employee of several sports car racing teams. From 1984 to 2001 Ramírez was coordinator of the McLaren Formula One team, including during the infamous Prost–Senna rivalry of the late-1980s. Early life The third of eight children, Ramírez was born in Mexico City and studied mechanical engineering at the National Autonomous University of Mexico (UNAM). Contrary to his father's desires he dropped out in 1960 to follow his friend Ricardo Rodríguez to Europe. Ramírez worked as apprentice mechanic for Scuderia Ferrari for two years. When Rodríguez died in a racing crash in the Mexican GP in 1962, Ramírez first took a job at Maserati and later at Lamborghini as a mechanic of their new line of high-performance road cars. In 1964 he moved to England where he worked for Ford on the GT40, before joining Dan Gurney’s All American Racers team in 1966. Formula One career During the 1960s and '70s Ramírez worked for several teams, including Dan Gurney's Eagle, Tyrrell, where founder Ken Tyrrell advised him to keep a diary of his time in the sport, and for Wilson and Emerson Fittipaldi in their Fittipaldi Copersucar F1 team. In December 1983 Ramírez joined the front-running McLaren Formula One operation as Team Coordinator, becoming close friends with many top drivers including Alain Prost, Ayrton Senna, David Coulthard and Mika Häkkinen. In 2001, after more than 40 years, Ramírez retired from the Great Circus and was advised by McLaren team manager Ron Dennis not to write his life story as no one would be interested. Ramírez was left in little doubt that Dennis's true aim was to stop any undesirable details of the team's inner workings from becoming public.
