HARLEY-DAVIDSON FOUNDERS INDUCTED INTO LABOR HALL OF FAME

Harley-Davidson’s four founders, William S. Harley, Arthur Davidson, Walter Davidson and William A. Davidson, were inducted into the U.S. Labor Hall of Fame on October 13.

A public ceremony was held at the U. S. Department of Labor in Washington D.C. to honor the founders’ ongoing impact on the Unites States’ labor force. U.S. Secretary of Labor Elaine L. Chao chronicled the success of the Motor Company and presented the honor to Bill Davidson, Harley-Davidson director of motorcycle marketing and great-grandson of founder William A. Davidson.

In 1903, founders William S. Harley, Arthur Davidson and Walter Davidson made the first production Harley-Davidson motorcycle available to the public. By the end of 1907, the Harley-Davidson factory was fully operational and the staff had grown to eighteen members including William A. Davidson. Today, more than 100 years since its founding, Harley-Davidson employs more than 8,500 people in the United States alone.
