Joseph Wilson Swan (1828 - 1914), an English physicist and chemist noted for his development of the light bulb. Swan received a British patent for his device in 1878, approximately a year before Edison. The most significant feature of Swan's lamp was that there was little residual oxygen in the vacuum tube to ignite the filament, and the filament was thus able to glow almost white-hot without catching fire. Swan eventually collaborated with Edison in the commercial development of electricity and the light bulb, using the trademark "Edi-Swan.” Swan also made notable contributions to the field of photography included bromide paper, the paper commonly used in modern photographic prints, and the carbon process for printing.
