De Moleyns Patented the Incandescent Lamp

Frederick de Moleyns patented the incandescent lamp in 1841. The lamp used carbon powder heated between two platinum wires to produce a brief light. The first filament light bulb was invented by Joseph Swan in 1860 using carbonized cotton filaments in a vacuum inside a glass bulb. On October 21, 1879, Thomas Alva Edison of Menlo Park, NJ, USA produced a similar design, until both Swan and Edison merged patents.
