"William" Bourque (often known as "Billy", March 30, 1879 – August 19, 1909) was a Canadian racing driver, born in West Farnham, Québec.
He drove primarily for the team operated by Massachusetts-based auto maker, Knox.
Later that day, driving car number 3,[3] he was killed in an accident during the feature Prest-O-Lite Trophy Race.
Witnesses said Bourque's fatal crash occurred when he looked back after being notified by his riding mechanic, Harry Holcomb, that another car was approaching on lap 58.
Bourque sustained a fractured skull and punctured lung, and later died in the hospital, making him the first driver to be killed at Indianapolis.
