Beginning in 1932 and continuing for only a few years, the Emerald Electric Co., of Adrian, Michigan, manufactured single-phase and polyphase induction motors. In about 1940 the business seems to have relocated to Toledo, Ohio and continued there is a low-key way for about another decade. Data on this maker is very sparse.
