Harvey Ernest Postlethwaite (4 March 194415 April 1999) was a British engineer and Technical Director of several Formula One teams during the 1970s, 1980s and 1990s. He died of a heart attack in Spain while supervising the testing of the aborted Honda F1 project. Early career After leaving the Royal Masonic School for Boys, Harvey Postlethwaite attended the University of Birmingham, England to study mechanical engineering and graduated, with a BSc and then a doctorate, during the 1960s. He was a keen follower of motor sport, competing in a Mallock at club level for a while. After graduation Postlethwaite joined ICI as a research scientist, but bored by this he soon began to pursue a career as a race car engineer, joining March in 1970, then aged just 26. Postlethwaite worked on the fledgling company's Formula 2 and Formula 3 cars but was lured away to join the Hesketh Formula One team who were a March customer. The Hesketh team was well known for an unconventional approach to Formula One—Postlethwaite was himself considered 'eccentric': "The Doc's explanation of his move to Hesketh was that 'They got me drunk'." Formula One Working to modify and improve the novice team's March 731 chassis, Postlethwaite elevated the team into serious contention and the following year designed the team's car from scratch. 'Doc' Postlethwaite's Hesketh 308 secured a number of podium positions. The following year he further developed the car's unusual rubber spring suspension and saw his creation take victory at the Dutch Grand Prix in the hands of James Hunt. By Lord Hesketh could no longer afford to run the team and sold out. Postlethwaite went with his cars to the newly founded Wolf–Williams Racing, headed by Walter Wolf and Frank Williams, but the results were poor and the owners soon went their separate ways. Postlethwaite remained with Wolf, designing the team's challenger, the WR1. Success was immediate with Jody Scheckter taking victory at the season's opening race. Two more wins and a number of podium results followed and Scheckter eventually finished second in the Drivers' Championship. Although Postlethwaite remained with the team until they were never to repeat their success. When Walter Wolf closed the team down at the end of 1979 he transferred, along with the Wolf cars and driver Keke Rosberg to the Fittipaldi Automotive team. He produced a new design, the F8, for the latter half of 1980 but
