Indianapolis 500 and the Motor Speedway

Indianapolis Motor Speedway Historian Donald Davidson is believed to be the only full-time historian employed at any race track in the world.

A passionate interest in the "500" since his early teens irresistibly drew the English-born-and-raised Davidson to the Speedway for a three-week visit in May 1964. Having committed to memory a plethora of trivial details during the seven years it took for him to save up for the trip, he was able to delight both active and retired participants with year-by-year recitations of their careers.
