Arlington Heights, Illinois, is a city of about 76,000 people, making it Chicago's largest northwest suburban municipality. Arlington Park Racetrack was opened in 1927 when over 20,000 spectators came to witness jockey Joe Bollero win the first race aboard Luxembourg.
In 1933, Arlington Park made a massive step in horse racing history when it released the first all-electric Totalisator, a computer system that registers bets and divides the total amount bet among those who won. This system not only reduced the time between races but also increased the credibility of wagering information.
In 1936, Arlington Park installed the first photo-finish camera in the Chicago area. Called the Eye in the Sky, the high-speed motion picture camera quickly showed its value as it all but eliminated the need for judge's decisions on close matches.
In 1981, Arlington Park held the "Arlington Million", the world's first "million" dollar race. Jockey Bill Shoemaker, riding John Henry, won the race by edging out 40-1 long shot, Bart. This come-from-behind victory was an amazing accomplishment and a bronzed statue of John Henry was placed on the top of the paddocks at Arlington Park.
Arlington Park revealed a new state-of-the-art Polytrack surface on its main track when it opened its 80th season in May 2007. Statistics strongly indicate that synthetic racing surfaces are kinder on horses than conventional dirt tracks and that they greatly reduce the number of injuries and breakdowns. Arlington Park became the first track in the Midwest to go synthetic.
