In 1924, the company started Kohler Stables and became famous in later years for breeding Morgan and Warmblood horses. In the same year, Kohler formed a Quarter Century Club to honor its employees with 25 years of service. This was one of the first of these clubs in American industry. Kohler introduced an electric sink in 1926 but it was discontinued due to the Great Depression. For World War II in 1941, Kohler converted most of its production to manufacturing torpedo tubes, shell fuses, and other military components. They would manufacture plumbing fixtures and generators only for war housing, war industries, hospitals, and military use. In 1948, Kohler began producing small engines. In 1954, a strike closes the factory but it reopens within two months, and the strike continues for six years.
