Oct 21, 1879 – the day light came to the world

The world lived in utter darkness since time immemorial and perhaps would have continued to do so for many more years till on this day, the 21st October, Thomas Alva Edison invented the first incandescent light bulb in 1879. Although, he was neither the first nor the only person trying to invent an incandescent light bulb, as there have been others trying to do what Edison did and took the lead.

The very bulb today lightens up our dark nights and one doesn’t feel whether it is day or night. An incandescent lamp is glass tube in which a filament is heated to incandescence by an electric current. Today’s incandescent light bulbs use filaments made of tungsten rather than carbon of the 1880’s. To these bulbs, now another revolutionary invention of energy saver bulbs has been added, which produce more energy and light with lesser electrical input as compared to an ordinary an incandescent bulb.

Edison lived with 1,093 patents issued to him than any other inventor till date. Besides this revolutionary invention, Edison is also credited with inventing the phonograph and the motion-picture camera, besides making contributions in the fields of telegraphy, telephone communications, and several business procedures. He even predicted the idea of an aero plane as far back as 1871, when he said on New Year’s Day, 1871, “A Paines engine can be so constructed of steel & with hollow magnets . . . and combined with suitable air propelling apparatus wings . . . as to produce a flying machine of extreme lightness and tremendous power.”

I could go on and on but it would better to read the following link on the man who brought light to the world on this day October.
