A riding mechanic was a mechanic that rode along with a race car during races, and who was tasked with maintaining, monitoring, and repairing the car during the race. They also communicated with the pits and spotted from inside the car.
Riding mechanics were also referred to by the term mechanician. The position is largely associated with the early years of Championship car racing and the Indianapolis 500, however, they were also utilized in grand prix racing for a period of time.
Riding mechanics were used by most cars in the Indianapolis 500 from 1911 to 1922, and again from 1930 to 1937. In the first 500, driver Ray Harroun notably drove solo, the only car in the field without a riding mechanic. He famously affixed a rear-view mirror to the car, in order to see cars behind him (a task normally accomplished by the mechanic). Harroun is famously regarded as the first driver to utilize a rear view mirror, however, he said he got the idea from seeing a mirror used for the same purpose on a horse-drawn vehicle in 1904.
Starting in 1912, riding mechanics were made mandatory for all races of 100 miles or longer (which included Indianapolis). In 1923 riding mechanics were made optional, and only one team utilized them. They were brought back from 1930 to 1937 and made mandatory once again. From 1938 on, they were again deemed optional, but no teams in the starting field used one ever again. In the years immediately following WWII, nearly all two-man cars had been parked, or converted to single-seaters. Eventually, in 1964, riding mechanics were formally abandoned.
The mechanics sat in a passenger seat, typically to the outside of the driver, a precarious position close to the retaining wall. Some cars, however, did have the positions reversed, with the riding mechanic on the inside. Due to the close quarters, many were of short stature and small build.
Some notable riding mechanics are Harry Holcomb, Robert Bandini, and Monk Jordan. The last living Indy 500 riding mechanic Joseph F. Kennelly died in September 2011. A small handful of riding mechanics were also drivers of their own right. Two-time Indianapolis 500 winner Jimmy Murphy started his racing career as a riding mechanic. While accurate records are incomplete and spotty overall, the identification of riding mechanics from the history of the Indianapolis 500 is mostly complete and fairly reliable.
