It was amazing to think that anyone would travel 500 miles in a crude seat and an awkward sitting position, let alone race that way. Granted, the average speed that year was only about 75 miles an hour, but that’s pretty fast in rickety race car.

Fans of racing lore, like me, know the story of Ray Harroun’s victory well. In those days race cars carried both a driver, and a riding mechanic. The mechanic had many jobs, but high on the list was keeping track of the competition. Ray and his team decided they could save weight by making the car a single-seater. Of course that meant that Ray was on his own when it came to watching for other cars.

Thus was born the rear view mirror. It sat high on the cowling right in front of the driver on four spindly legs. According to racing legend, Ray got the idea from a mirror he’d seen mounted on a horse drawn carriage years before. Ironically, while it caused plenty of controversy, the mirror was actually a flop. Harroun later told speedway historian Donald Davidson that it shook so badly he couldn’t see a darn thing.

Harroun wasn’t just another driver. He considered himself more of an engineer and was an important part of the crew that built the Wasp. He later went on to found the Harroun Car Company (which unfortunately folded in 1922). His simple invention didn’t change racing right away. Riding mechanics were the norm at the speedway until 1923. While they came back between 1930 and 1938, they’re usually a long forgotten part of racing history.

Technically, I guess we’d have to give credit to some horse drawn chauffeur who came up with the idea of using a mirror to keep track of what was coming from behind. But Harroun deserves his share of credit as the guy who put it on the automotive map. Even if it didn’t really help him much when it came to winning the first Indy 500.
