Saturday 5th October 1912
American Grand Prize, the seventh and final race of the 1912 Grand Prix season, was held at the Wauwatosa Road Race Course in Milwaukee, Wisconsin. Sanctioned by the American Automobile Association, Caleb Bragg in a Fiat S74 won the race by over 15 minutes from Erwin Bergdoll. Bragg’s average speed was 68.397 mph (110.074 km/h). The event was marred by the death of two time and defending winner David Bruce-Brown in a practice accident. His car was repaired by Barney Oldfield and driven to a fourth place finish.
