Sir Joseph Wilson Swan, scientist and inventor, c1900. Swan invented the incandescent electric lamp in Britain at about the same time as Thomas Edison patented it in the USA. He also invented a vacuum pump for light bulbs and several photographic processes. Later, Edison joined up with Swan to form the Edison & Swan United Electric Light Company.
