A Brilliant Lot: Letter Signed by Thomas Edison

Swann Galleries will be offering illuminating material related to scientists and inventors in its auction of Autographs on October 29. Among the many highlights is a Letter Signed by Thomas Edison to Brazil's Minister of Agriculture, circa December 1880.


Edison's letter explains his intention to send an envoy to search Brazil for a vegetable fiber filament that would help him “to perfect the electric light and bring it into practical everyday use” and is estimated to sell between $8,000 and $12,000.
