Show T. A. Edison Thomas Alva Edison, born at Milan, Ohio, Feb. 11, 1847, of Dutch and Scottish parents, had only three months of schooling (at Port Huron, Mich.). IN SPITE of this handicap, he became one of the world's greatest inventors, and one of America's most distinguished sons. A good case can be made that Edison was the greatest inventive genius of all time. While still in his teens he invented in-vented stock tickers, telegraph systems and an electric pen, which developed into the mimeograph. He invented the carbon transmitter which helped considerably to produce pro-duce the telephone. He pioneered significantly in the development of both the pho-nograph pho-nograph and dictating machines. HE DID more than any other man to invent the electric light having produced his first incandescent light on Oct. 21, 1879. He discovered methods to develop electric heat, light and power systems sys-tems and electric trains. Edison invented processes to concentrate and separate iron ores and facilitate mining operations. In later years he invented cameras and film processes pro-cesses to produce motion pic-tues pic-tues ging that industry its start. THE AMERICAN genius also invented the radio tube shortly before his death in 193 1 , at the age of 84. He is one of few famous figures in history his-tory whose contribution to the world has been appaised more and more highly with the passing pas-sing of time. That one man could accomplish so much for science, and people everywhere, every-where, is today still an astonishing asto-nishing realization. |
