I found this information on line:
"The Photogenic company was founded in 1903 by James H. Wagenhorst and in 1922 was incorporated as the Photogenic Machine Company with John P. Young as president and treasurer, E. G. Perkins as general manager and G. W. Perkins as secretary.  The company is
still in operation
, headquartered in Bartlett, Illinois.  The Wagenhorst company seems to have been dedicated to inventions with patents in diverse industries from wagons to guns, printing and photography equipment.  It's chief product in photography was an arc lamp called the Wagenhorst High Power Twin Arc Lamp.
The company was known for its Rheostat control device for their early photography studio arc light, manufactured by the Company, then located in Youngstown, Ohio.  The rheostat let the lamp be set to various light intensities from 10 to 50,000 candle power or from a soft North light to a brilliant sunshine effect.
It was called the Rheostat control device for early photography studio arc light."
