The Schmidt Superheating Company Limited was formed in 1908 for the purpose of developing the use of Dr Schmidt’s design his smoke tube superheater in Great Britain. In 1910 the progress which had been made by Dr. Schmidt in Europe resulted in the formation of The Locomotive Superheater Company (now The Superheater Company) in the United States. The Schmidt Superheating Co., Ltd., was reorganised in 1919, and renamed the Marine and Locomotive Superheaters Ltd., and, finally, in 1924, after amalgamation with the Superheater Corporation, Ltd., assumed its present title of The Superheater Company, Ltd.

The MeLeSco emblem found in catalogues and other literature may have come about as the result of the shortening of the MarinE and LocomotivE Superheater Company.
