After the discovery of X-rays by Wilheim Roentgen in 1895 they branched-out into the production of medical X-ray equipment. Subsequent mergers and acquisitions by 1916 caused Victor Electric Corporation to become one of the global leaders in the production and supply of electrical medical and X-ray equipment. In 1920 they merged with General Electric and were renamed a Victor X-Ray Corporation and operated as an autonomous subsidiary but was eventually fully absorbed into GEC by 1930.The current lot utilises induction coils most likely configured in a manner devised by Oudin type induction coils in order to be able to deliver electrotherapy compatible with Jacques Arsene D'Arsonval's principles whose experiments utilising AC currents set at over 5,000Hz led to the development of diathermy as a treatment process.
