Thomas Alva Edison, the famous inventor, built his first science laboratory in the basement of his home , at the age of 10! He would spend hours on end in his laboratory. Fed up of seeing him cooped up thus, his father would bribe him with a penny to go out. But he would use the penny to buy more chemicals for his experiments. Edison filed 1,093 patents, including those for the lights bulb, electric railways and the movie camera. When he died in 1931, he held 34 patents for the telephone, 141 for batteries, 150 for the telegraph and 389 patents for electric light and power.
