The complete history of light.

...from an American perspective, Edison bought the patent for electric lamps from Canadians Woodward and Evans for 50,000 USD and further developed it, long lasting filament was actually Sir Joseph Swan`s invention, Edison developed the pinch and mounting posts , hence the joint venture in Europe Ediswan, neither could function without other patents. Edisons genius was marketing.


Missing is American John Wellington Starr who had evacuated lamps 40 years before anyone else, stress killed him though and he is buried in a paupers grave in Birmingham.
