Sherwood's legacy dates back to 1903 when William Sherwood and David Buick, the founder of General Motors, started a copper and brass plumbing business. Although their paths diverged, Sherwood's entrepreneurial spirit led him to establish a foundry and machine shop that catered to the growing automotive industry in Detroit.
In the 1920s, Chris-Craft, a pioneer in the inboard-powered pleasure boat industry, recognized Sherwood's expertise in plumbing and custom manufacturing. Together, they developed the first seawater pumps specifically designed for marine inboard engines.
During World War II, Sherwood played a critical role in supporting the U.S. Navy by supplying marine engine coolant pumps. Their products were instrumental in ensuring the reliability and performance of landing craft and other naval vessels.
