...early as 1820, inventors were homing in on the principles that would lead to the first electric illumination. An English inventor, Joseph Swan, took their early work and developed the basis of the modern electric lightbulb in 1879 - a thin paper or metal filament surrounded by a glass-enclosed vacuum. When electricity runs through the filament, the bulb glows. Edison refined the design, trying filaments made out of platinum and cotton before eventually settling on carbonized bamboo, capable of burning for more than 1,200 hours. With Edison's design - and the settlement of a lawsuit with Swan that resulted...
