Certainly neither inspiration nor industry were lacking in this prolific inventor, who was granted a total of 1097 patents — an all-time record. Thomas E. Edison was born in Milan, Ohio, in 1847. He had but a few years of formal schooling, but his mother taught him at home, and he early developed an interest in science. He took his first job as a railroad newsboy and "candy butcher", and then became an itinerant telegrapher, an occupation that started him on the road to developing his amazing potentialities for electrical innovation. His first commercially successful invention was an improved stock ticker, used by speculators in gold and securities. He used the $40000 he got for this — a small fortune for a 23-year-old — to open a factory in Newark, New Jersey. There he made telegraph instruments and stock tickers, and methodically set about turning out further inventions. In 1876 Edison moved from Newark to Menlo Park, New Jersey, where he established his "invention factory", the first industrial research laboratory. A torrent of discoveries and inventions was soon pouring from his fertile brain. Edison's invention, in 1877, of a "talking machine" that could record, store, and reproduce human speech or music was revolutionary. His only discovery in pure science came in 1883: it was the Edison effect. He patented this discovery in 1884 but did not investigate it further. Other scientists used it to develop the electronics industry, particularly radio and television. Download 77.82 Kb. Do'stlaringiz bilan baham: |
