EDISON, Thomas Alva.

The US patent has been selected as one of the 100 most important documents in the US National Archives (ourdocuments.gov/doc.php?flash=true&doc=46). "The invention that Edison is most remembered for is, by far, the electric light bulb. At the age of thirty-one, he decided to focus his energies-and the manpower of the Menlo Park facility-toward c … [Click Below for Full Description]
