The Engeln Electric Company, Cleveland, Ohio, started business late in the second decade as makers of X-ray accessories and then of heavier equipment (dental and mobile units, fluoroscopes, X-ray tables, etc), but, after several unsuccessful associations, disappeared from the market by the Big Depression in 1930.
