By 1919 there was another trade at this address in the form of Charles Stevens electricians. This company later became C. Stevens & Son, Electrical Engineers and Contractors and this property was renamed Osram House.
The word Osram is a hybrid of the names of two filament materials, osmium and wolfram (or tungsten as it is now known). It was registered on April 17, 1906 with the German Imperial Patent Office in Berlin as the trademark for “electric incandescent and arc light lamps”. By 1933, still using the address Osram House, the Stevens’ had been replaced by Mr F.R. Homer, a radio and electrical engineer.
