One can correctly infer that the two industrial tank engines were named for the two brothers who founded the company. The small 20-tonners served Solvay-Werke's soda ash and bicarbonate plant in Bernburg. Ernst Solvay had applied for a patent for a process that produced soda ash using salt, ammonia, and carbonic acid. Turned down for lack of novelty, Ernst consuclted with a lawyer who advised him to apply to patent the particular succession fo equipment and operations. This variant proved successful in 1863.
