American automobile-racing driver, whose name was synonymous with speed in the first two decades of the 20th century.

A bicycle racer from 1894, and briefly a professional boxer, Oldfield was hired in 1902 as chief mechanic for Henry Ford's racing team. He soon became the team's driver and achieved fame by guiding the Ford-Cooper 999 to two victories over Alexander Winton's supposedly invincible Bullet. On June 15, 1903, at Indianapolis, he accomplished the first mile-a-minute performance in an automobile (59.6 seconds); in August 1903 he drove five miles in 4 minutes 55 seconds. At Daytona Beach, Fla., March 16, 1910, in his Blitzen Benz, he set a world speed record of 131.724 miles per hour. Despite his success he came to dislike auto racing, calling the sport a “Roman circus”; he was disgusted at the great publicity accorded him following two racing accidents in which spectators were killed. After his retirement in 1918, he became a well-known advocate of driving safety.
