You might think that Harley-Davidson was founded by two guys whose last names were Harley and Davidson, and you would be partway right.
It's actually one Harley and three Davidsons, and it took all four of them working together to create a brand that would revolutionize transportation and America.
Harley-Davidson was founded in 1903 in Milwaukee, WI and officially incorporated in 1907 with Walter Davidson acting as the first president. Arthur Davidson became the first general sales manager and the secretary while William Davidson was the first works manager. William Harley, meanwhile, became the chief engineer and treasurer.
Given the ratio of three Davidsons to one Harley, you may be wondering why the company wasn't called Davidson-Harley. Since the original idea for the motorcycle came from William Harley, the gang thought it was only fair to have his name first.
The first Harley-Davidson factory was a wooden shed in the Davidson's backyard. The current headquarters stands in the same location - in a more prominent building, of course.
The first three motorcycles produced by Harley-Davidson in 1903 all had a buckle crank, a single-cylinder engine, pedals, and a leather drive belt. You would pedal until enough engine compression was built up, at which point the engine took over.
Harley, however, wanted to take bikes to the next level, which meant a two-cylinder engine. Perfected by 1909, the engine, called a V-Twin, could reach speeds as high as 60 mph.
With such a feat, Harley-Davidson's production rose to 3,200 machines by 1910.
By 1914 the USPS using 4,800 bikes to deliver mail. Soon, the military was using Harley motorcycles as well. By the 1950s, police departments nationwide were also using a Harley-Davidson.
