89 years ago, on October 18, 1931, Thomas Alva Edison passed away. Thomas Alva Edison is one of the most prolific inventors in history. He made a big contribution to the world thanks to his invention of the incandescent lamp. Edison died in West Orange, New Jersey, at the age of 84. As a young man, Edison received a formal education like most Americans at that time.

When he 16 years old, He got a job as a telegraph operator and devoted much of his natural energy and ingenuity to improving the telegraph system itself. In 1869, he pursued his invention and in 1876 moved to a laboratory and machine shop in Menlo Park, New Jersey

Edison's experiments were guided by his extraordinary intuition, although he was careful to employ assistants who provided the mathematical and technical expertise he felt was lacking. At Menlo Park, Edison continued his work in the telegraph field, and in 1877 he stumbled upon one of his wonderful inventions, the phonograph, while working on a method to record telephone communications. The public demonstration of the phonograph made the Yankee inventor world famous, and he was nicknamed the "Witch Menlo Park".

Among important inventions, Edison and his assistants developed the first practical incandescent light bulb in 1879, and a pioneer of film cameras and projectors in the late 1880s. In 1887, he opened the world's first industrial research laboratory at West Orange, where he employed dozens of workers to systematically investigate specific subjects.

He continued working into his 80s and obtained 1,093 patents during his lifetime. He finally died at his New Jersey home on October 18, 1931.
