Detailed explanation-2: -Edison did not actually invent the light bulb, of course. People had been making wires incandesce since 1761, and plenty of other inventors had demonstrated and even patented various versions of incandescent lights by 1878, when Edison turned his attention to the problem of illumination.

Detailed explanation-3: -By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting.

Detailed explanation-4: -The famous story goes, Edison failed to refine the light bulb (one of the few creations he merely refined but did not invent) so many times it took him 10, 000 attempts to perfect. However rather than accepting failure 9, 999 times he is quoted as answering questions on his failures as rather: ‘I have not failed.
