Saturday 15th July 1911
Jake DeRosier, on an Indian, defeated Charlie Collier, on a Matchless, in a 10 lap (22 mile) motorcycle race at Brooklands, England. He was one of the first factory-backed motorcycle racers of the early 20th Century. He rode for Indian and then Excelsior, and was the fastest rider in the United States in the early 1900s.While Jake DeRosier was widely respected for his skills at the wheel of a motorcycle, he spent much of his career injured in spectacular accidents. He broke his left leg three times, his left forearm once, had one rib removed, fractured his skull, severed an artery and suffered serious leg burns from flaming engines. He suffered the most serious injuries of his career on March 12, 1912. Injuries to his left leg and thigh were extensive. He endured three corrective surgeries, losing his life to complications from the final operation on February 25, 1913.
