William G. Henderson is widely recognized as a truly innovative designer of early motorcycles and is especially well-known for his design of four-cylinder engines. He was the original owner of the Henderson Motorcycle company – which was founded in 1911. In 1917, he sold his company to Ignatz Schwinn, the owner of the Schwinn company that made bicycles and Excelsior Motorcycles.
