It was an event of 1914. A  scientist was very busy in laboratory for his scientific inventions. Due to certain cause fire took place and brunt the laboratory. The fire touched the sky. Not being worried the scientist called his son and sent him to call his mother to see this rare incident. After few moments the wife of the scientist came and became worried and impatient after seeing it. But the scientist said to his wife “we should thank God as he made a chance for us as a result of which entire sin of mine is going to be burnt.” He also said, “Again I have to start my work with previous enthusiasm and every loss opens the door for benefits.” He was believing in the fact that “where there is a will there is a way”. The patient, hard working and God fearing scientist of that day was Thomas Alva Edison.

Thomas Alva Edison was born in Milan, Ohio of U.S.A. in Feb. 11, 1947. He was very poor. He had very little formal schooling. He had developed keen interest in science and scientific invention from his childhood. At the age of 10 he had established a small laboratory in his home. He was also selling news papers and candy on trains to maintain his livelihood when he was a boy of 12. He worked at a telegrapher (1862-68) before deciding to pursue invention and entrepreneurship. Throughout much of his career, he was strongly motivated by efforts to overcome his handicap of partial deafness. In spite of all these physical and financial difficulties he continued his laboratory experiments. He had invented carbon-button transmitter, alkaline storage battery, movies camera, an instrument for viewing moving pictures, telegraph message sending machine, phonograph, electric light bulb and some other machinery instruments related to electricity. He held a world record of 1093 patents, nearly 400 of them for electric light and power. Also he created the world’s first Industrial Research Laboratory in Menlo Park. New Jersy, USA. In fact he laid the basis for the technological revolution of the modern electric world. He left us in Oct 18, 1931 as a result of which our world lost a great scientist for ever.
