Jim_Rathmann_(racing_driver)--A.J._Foyt

Royal Richard "Jim" Rathmann (July 16, 1928 – November 23, 2011), was an American racing driver who competed primarily in Championship Cars. Rathmann is best known for winning the Indianapolis 500 in 1960, emerging victorious after a race-long duel with Rodger Ward - as recently as 2023, a panel of fans and historians voted Rathmann's victory as the greatest '500' of all time. In Europe he is well-known for winning the 1958 Race of Two Worlds.
Rathmann and his older brother swapped names while teenagers. As a 16-year-old going by the name of Dick Rathmann, he wanted to start racing. To enter races, he borrowed his older brother's I.D. and assumed the identity of "Jim Rathmann." The name change stuck for life in public circles.
