Thomas Alva Edison was an American inventor born in 1847 in Ohio. After working as a telegraph operator as a youth, he went on to establish America's first industrial research lab, known as Menlo Park Laboratory, where he invented many devices including the phonograph and incandescent light bulb. Through his work at Menlo Park and later companies, Edison emerged as a leading inventor and helped drive innovations in electric power, mass communication, and motion pictures through both research and business ventures.

10. Emergence as a Leading Inventor

From 1870 to 1875, Edison worked at
New Jersey, where he developed
telegraph-related products for both
Western Union Telegraph Company
and its rivals.

In 1876, His major innovation was the
establishment of an famous industrial research lab which was
named as Menlo Park Laboratory.

In 1877, He invented the carbon
telephone transmitter for the Western
Union Telegraph Company.
His phonograph (patented 1878) was
successful instrument of its kind.

11. Innovations with Electric Light

In 1878, Edison set up the Edison Electric
Light Company and began research and
development.

He made a breakthrough in October 1879
with a bulb that used a platinum filament.

In 1881, he set up an electric light company in Newark, and the
following year moved his family to New York.

By 1889, AC current would come to dominate the field, and the
Edison General Electric Co. merged with another company in
1892 to become General Electric Co.

12. Conclusion
In 1931, Edison succumbed to complications from diabetes. He was
survived by his second wife and their three children, as well as his
three children by his first wife. By the time he died on October 18,
1931, Edison had amassed a record 1,093 US patents in his name, as
well as patents in other countries.
Everyone had heard of the "Wizard" and looked up to him. The
whole world called him a genius. But he knew that having a good
idea was not enough. It takes hard work to make dreams into reality.
That is why Edison liked to say,
