"In honor of Sir Joseph Swan (1828-1914) and Thomas Alva Edison (1847-1931), the two men, which changed the way people live in homes around the world, inventing the incandescent light bulb. A bit of history: 'English Sir Joseph Wilson Swan in 1878 in Great Britain, patented the first light bulb ever made, but this, it proved impractical. The combustion system, was a thick filament carbon emitting gas, and very quickly, soot covered the interior of the bulb. Was then, the American Thomas Alva Edison, who in 1879 patented a high-strength thin filament, which did not emit gases. Swan also incorporated this improvement in his bulb, but was sued by Edison for patent infringement. In the end, common sense prevailed, Swan and Edison agreed, and in 1880, they created the Edison & Swan United Light Company. ..... and now light!"
