lewis-lattimoreLewis Latimer (1848 – 1928)

What He Invented: The Carbon Filament For The Light Bulb.

Why It’s Important: Latimer is one of the greatest inventors of all time. Thomas Edison may have invented the electric lightbulb, but Latimer helped make it a common feature in American households. In 1881 he received a patent for inventing a method of producing carbon filaments, which made the bulbs longer-lasting, more efficient and cheaper.

In 1876, he worked with Alexander Graham Bell to draft the drawings required for the patent of Bell’s telephone.
