W. A. Case & Son Manufacturing, usually referred to by its wordmark Case, was an American manufacturer best known for its plumbing fixtures. Founded in 1853 by industrialist Whitney Asa Case, the company initially manufactured boilers, radiators, and ran a heavy coppersmithing shop for steamboats and locomotives. It was best known for its metalwork by the time of Whitney A. Case's death in 1892. His son and successor, Whitney G. Case expanded into the plumbing and household markets, and by 1910 the company had expanded to become the largest supplier of copper engineers’ and plumbers’ supplies in the United States.
