Most of these inventions were not completely original but improvements of earlier inventions. However, one of Edison's major innovations was the first industrial research and development lab, which was built in Menlo Park and West Orange. Throughout the 20th century, Edison was the world's most prolific inventor. At the beginning of the century ...
Edison in 1861. Thomas Edison was born in 1847 in Milan, Ohio, but grew up in Port Huron, Michigan, after the family moved there in 1854. [8] He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York).
Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.

Patent drawing for Edison's phonograph, May 18, 1880. Thomas Edison conceived the principle of recording and reproducing sound between May and July 1877 as a byproduct of his efforts to "play back" recorded telegraph messages and to automate speech sounds for transmission by telephone. [29] His first experiments were with waxed paper. [30]
Thomas Edison's work on two other innovations, the telegraph and the telephone, led to the development of the phonograph. Edison was working on a machine in 1877 that would transcribe telegraphic signals onto paper tape, which could then be transferred over the telegraph again and again. The phonograph was both in a cylinder and a disc form.
In December 1877, [5] Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. [6] Tin foil was not a practical recording medium for either commercial or artistic purposes, and the crude hand-cranked phonograph was only marketed as a novelty, to little or no profit.
At age 19 in 1879, William Dickson wrote a letter to American inventor and entrepreneur Thomas Edison seeking employment. He was turned down. That same year Dickson, his mother, and two sisters moved from Britain to Virginia. [4] In 1883 he was finally hired to work at Edison's laboratory in Menlo Park, New Jersey. In 1888, Edison conceived of ...
