At the Livermore-Pleasanton Fire Department located in Livermore, California, you can see the World’s Longest Burning Light Bulb.
It was first installed in 1901 and with the exception of a few days has been lit since then. You can view it live at www.centennialbulb.org. This would not be possible if not for a man born on September 4, 1848 in Chelsea, Massachusetts named Lewis Latimer.
Mr. Latimer, who became an employee of Thomas Edison in 1890, was the inventor of the method to cause the long lasting carbon filament. Before his invention light bulbs would burn out in just a few days. His invention helped the carbon filament to last month’s thus making the light bulb less expensive and more efficient. We can thank him for contributing greatly to electrical lighting in all of our homes.
Mr. Latimer is one of the unknown men who has had a large impact on the daily life of people all over the world for the past 100 years.
