From firstsuperspeedway.com Fiat driver Caleb Bragg won the 1912 running of the American Grand Prize held at a 7.88-mile public roads course in Wauwatosa, Wisconsin near Milwaukee. This race was overshadowed by two devestating accidents affecting two of the biggest names in the sport: David Bruce-Brown and Ralph De Palma. Bruce-Brown was killed in a practice accident and De Palma suffered the most serious injuries of his career when his Mercedes left the course late in the race, throwing him from the car. His abdomen was impaled by a corn stalk left over from recent harvest days. De Palma, who had won the Vanderbilt Cup over the same course just days prior, survived for one of the most successful driving careers in racing history, including his 1915 win in the Indianapolis 500.
