The Harley-Davidson Service School was born out of necessity during World War I. With the company concentrating on military production and shipping motorcycles overseas, military quartermasters and mechanics needed extensive instruction into how the motorcycles were built and how to maintain them. This led to the creation of what was then known as the Harley-Davidson Quartermasters School and was a three week intensive course.
After the war, Harley-Davidson chose to maintain its highly successful program and re-named it the Service School. Classes were opened up to all Harley-Davidson employees and dealers, offering the same type of instruction once given to military personnel. Harley-Davidson also operated a Sales School and classes for those who operated and maintained Harley-Davidson’s commercial vehicles, such as police motorcycles and golf cars. World War II saw a brief resurrection of the Quartermaster School, but, as before, the Service School returned after the war was over. In the 1990s, Harley-Davidson consolidated its various training programs into Harley-Davidson University.
