The great Inventor

Thomas Alva Edison was probably the greatest inventor. His first job was selling newspapers on trains, and later, at the age of 16, he got a job working in a telegraph office. Not all of Edison's inventions were successful. In fact his first one was a failure. Many that followed, however, were fright successes and Edison became famous. Most people regard him as a genius. Edison worked hard all his life, often working all night in his laboratory, and would not come home for days sometimes. When asked what makes a genius he said: "Genius is 99% perspiration and 1% inspiration." Although most of the inventions which made Edison famous were made in the first half of his life, Edison continued to work and invent till he was over 70, often working 16 hours a day! During his long and productive life, Edison made 1,300 inventions.

One of the most important inventions is the light bulb. Thomas Edison tried two thousand different materials in search of a filament for the light bulb. When none worked satisfactorily, his assistant complained, "All our work is in vain. We have learned nothing." Edison replied very confidently, "Oh, we have come a long way and we have learned a lot. We know that there are two thousand elements which we cannot use to make a good light bulb. Edison died October 18, 1931, at the age of 84.
