Dongan has a long history of building trusted products. Our company was founded in Albany, New York in 1909, known then as the Dongan Electric Instrument Company. Named for Governor Thomas Dongan—the first colonial governor of the Territory of New York—the company first produced ammeters and voltmeters for the growing automotive business. Lyle J. Hicks, an electrical engineer, acquired the company and later moved it to Detroit, Michigan, where it was renamed Dongan Electric Manufacturing Company.
