Edgar Worthington & Harry Kent

In the early 20th century, two visionaries—Seattle businessman Edgar Worthington and retired Coast Guard Captain Frederick Kent—helped shape the American trucking industry. In 1917, Worthington acquired the struggling Gersix Motor Company and partnered with Kent to revitalize it. After Kent’s retirement, his son Harry joined Worthington, and together they steered the company toward lasting success.

In 1923, the business was reincorporated as the Kenworth Motor Truck Company, its name combining “Kent” and “Worthington” to honor its founders. Based in Seattle, Kenworth quickly became known for its innovation and quality.

During the 1920s and 1930s, truck production rose from 80 units in 1924 to 156 by 1927, reflecting rapid growth and rising demand. Even during the Great Depression, Kenworth’s resilience stood out as it became the first U.S. truck manufacturer to make diesel engines standard equipment—a groundbreaking move that reshaped the industry. By 1940, annual production had reached 226 trucks.

Today, Kenworth is renowned for its legendary models, including the W-900 conventional and K-100 cabover. The legacy of Edgar Worthington and the Kent family continues to define the brand’s commitment to innovation, durability, and craftsmanship.

A century later, Kenworth proudly carries forward its founders’ vision—earning its reputation as the “World’s Best.”
