Thomas Alva Edison

  Thomas Alva Edison was born in 1847 in Ohio, America. As a little boy he was very inquisitive (好问的) . He always wanted to know how things were done. Very early in life he showed he was full of curiosity(好奇) , a quality(素质) which is so important to inventors. In 1869 he went to New York, where he worked for some time as a telephone operator. But soon he became interested in inventions. In a very short time they were his chief business. In order to carry on his business, which was to become his life's work, he built a lab at Menlo Park, where he had gone to live. His first great invention was a system of telegraphy (电报学) . Soon afterwards he invented the phonograph (留声机), the first form of the instrument that we now know as the gramophone or record player. The word “phonograph” means something that can “write” or record sound. Other scientists before Edison had thought of instruments which would do this, but Edison was the first to make an instrument which actually(实际地) worked. He also invented the incandescent lamp (白炽灯), the wire is heated by an electric current (电流) . People could now use electricity (电) to illuminate (照亮) their homes. By the time Edison died in 1931 he had about a thousand inventions.
