The OSRAM name was registered in 1906 by Auer-Gesellschaft. The name OSRAM derives from the names of two elements: Osmium, a metal; and Wolfram, the German word for tungsten. The company had been a pioneer in the development of the Osmium lamp and the tungsten filament lamp.
As a company, OSRAM traces its roots to 1919. OSRAM was the result of a merger between three companies: AEG, Siemens & Halske AG, and Auer-Gesellschaft. All three companies had been pioneers in the development of electric light.
OSRAM SYLVANIA in its current form was created in January 1993, when OSRAM GmbH acquired the SYLVANIA lighting and precision materials businesses in North America from GTE. The company remains a global leader in innovative lighting products and services.
