Tartanwizard... Thomas Edison did not invent the incandescent light bulb, this was first made and manufactured by Joseph Swan from Sunderland who worked in Newcastle upon Tyne. His invention was hampered by poor sealing and lack of a good enough vacuum. Edison used better tools some 20 years later to improve the vacuum and devised the well known screw fitting to make the device marketable. Another factor in Edison's success was the greater availbility of electricity generation and supply by that time. Joseph Swan went on to improve the filament material to increase the lifespan of the bulbs.
