Harley Davidson Service School

July 9, 1917 – The first Harley-Davidson Service School class takes place in Milwaukee.

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.
