what did Tomas Edison invent?

Answer 1

There's a good article at:
http://inventors.about.com/library/inventors/bledison.htm
that gives a lot of information about this.

Among his inventions are the telegraph, the phonograph and a practical incandescent lightbulb. To do this he needed to develop:
the parallel circuit,
a durable light bulb,
an improved dynamo,
the underground conductor network,
the devices for maintaining constant voltage,
safety fuses and insulating materials, and
light sockets with on-off switches.

Quite a list, hm?

There are other inventions listed there, too.
If you are interested in failures of Edison, you can read the article at:

That's pretty interesting reading as well.

Answer 2

Edison was now employed in Boston, but he devoted all of his spare time to doing research. He invented many things, including a vote recorder, a stock quote printer, a carbon telegraph transmitter, and he improved the telegraph-repeating machine that he invented previously. Through his inventions, Edison earned 40,000 U.S dollars. With this money, Edison established a lab. In 1876, he opened his new lab. From this lab, he made some of his most influential discoveries, including the phonograph in 1877, and the incandescent light bulb in 1879. After Edison invented the light bulb, he spent most of his time developing generators powerful enough to run light bulbs. In 1882, he built the first DC power plant in New York City. In 1887, he moved from Menlo Park, New Jersey to West Orange, New Jersey. In his new lab, Edison created even more inventions. He created a kinetoscope, a device used to play motion pictures in 1888, and he made his own battery, known as the Edison Storage Battery. He also made a phonograph, and using the phonograph and the kinetoscope together, he produced the first talking movie.

one of the most Important invention.

Answer 6

Thomas Edison invented Electricity.......

Answer 7

He developed the modern scientific method. He also developed a very lucrative business in the science field. He was one of several people who worked directly on the lightbulb project. His company developed it. He owned the company so his name is on the patents. (there are people out there who have to make a fuss over that) His labs also developed the motion picture camera. That was another project he had direct influence on.

Time Magizine ran an excellent article on sometime around the last two years. I found it quite informative about his life and work.
