Milwaukee was chosen as the venue for the 1912 American Grand Prize and Vanderbilt Cup with backing from the local Pabst Brewery and Milwaukee Auto Dealers Association. Initial plans to run the races in the suburb of Greenfield were abandoned when speculators were found to have snapped up prime grandstand locations. Instead a narrow eight-mile road course was drawn up in Wauwatosa Township seven miles to the north. Heavy rain delayed the Vanderbilt Cup for a couple of weeks before Ralph de Palma won a thrilling duel with Hughie Hughes. The Grand Prize was a tragic affair however for David Bruce-Brown, winner for the last two years, was killed in practice. Caleb Bragg's Fiat won the race despite a last lap clash with Ralph de Palma that left his rival with a broken leg.
