<human>: Dan Gurney was born to Jack Gurney and Roma Sexton. His father, John R. "Jack" Gurney, was a graduate of Harvard Business school with a master's degree. Dan's three uncles were each MIT engineers. His grandfather was F.W. Gurney who was responsible for the invention of the Gurney Ball Bearing.

Upon his retirement from Formula One, Gurney devoted himself full-time to his role as car maker and team owner. He was the sole owner, Chairman and CEO of All American Racers from 1970 until his son, Justin, assumed the title of CEO in early 2011. The team won 78 races (including the Indianapolis 500, the 12 Hours of Sebring, and the 24 Hours of Daytona) and eight championships, while Gurney's Eagle race car customers also won three Indianapolis 500 races and three championships.  In 1978, Gurney wrote an open memo to other race car owners with what is now known as the "White Letter" in which Gurney called for a series controlled more by the owners or "actual participants" than under the USAC banner. After much debate, CART was formed with Gurney and other owners like Roger Penske, Pat Patrick, and Bob Fletcher. CART began its first full season of competition in March 1979 and thus the first split in open wheel racing began.  AAR withdrew from the CART series in 1986, but enjoyed tremendous success with Toyota in the IMSA GTP series, where in 1992 and 1993 Toyota Eagles won 17 consecutive races, back-to-back Drivers' and Manufacturers' Championships, and wins in the endurance classics of Daytona and Sebring.  The team returned to CART as the factory Toyota team in 1996, but left again after the 1999 season when Goodyear withdrew from the series and Toyota ended their relationship with the team. In 2000, Dan campaigned a Toyota Atlantic car for his son, Alex Gurney under the AAR banner.  In 1990, Gurney was inducted into the International Motorsports Hall of Fame. He is also a member of the Motorsports Hall of Fame of America, the Sebring International Raceway Hall of Fame, and the West Coast Stock Car Hall of Fame.
