George Walther Sr. (August 13, 1876 – April 10, 1961) was an American inventor, engineer, businessman, civic leader and the holder of over 100 patents for truck wheels, brake drums, fifth wheels, and landing gear/legs for the trucking industry. He was the founder of the Dayton Steel Foundry.
Walther developed the first practical cast steel wheel for solid rubber tires. This was a basic but critical contribution to the evolution of the early trucking industry and the U.S. Army trucks in World War I.
Walther followed the design of the cast steel wheel for solid rubber tires with the design of a cast steel wheel for pneumatic tires and then the design of an improved brake drum. When semi-trailer trucks were developed, he designed improved versions of the fifth wheel and landing legs for semi-trailer trucks. Walther's engineering skills resulted in patents for many developments of truck wheels, brake drums, fifth wheels, and landing legs that have helped to expand the role of trucks in the transportation industry.
