Al Unser Sr., a legend in the world of auto racing, is one of only three drivers to have won the Indianapolis 500 four times. Unser, a member of the second of three generations of Unsers to race cars, also shares the distinction of having won races on paved ovals, road courses, and dirt tracks in a single season with only two other Indy drivers. In fact, Unser managed that latter feat three years in a row—1968, 1969, and 1970. Unser has partnered with son, Al Jr., a racing star in his own right and sometime competitor with his father, to create a museum that will appeal to both adults and children. Before retiring, Unser Sr. compiled an enviable record on the Indy car circuit of thirty-nine wins, accumulating more than $6 million in winnings. Collectively, the Unsers are the winningest family at Indianapolis, having collected a total of nine checkered flags, or more than 10 percent of the races run at Indy.
