- "Tom, how am I going to generate that kind of power? It can't be done, can it?"
- —Dr. Emmett Brown
Edison developed the first working incandescent light bulb and electrified many portions of the United States.
When trying to persuade a heartbroken Emmett Brown to continue his path on science, Marty McFly brought up Thomas Edison and the light bulb as an example of an invention that has made a positive difference.
Shortly after, Marty claimed that he didn't have the guts to follow his dreams, and dismissed his aspirations as daydreams. Emmett responded by pointing out that Thomas Edison, Albert Einstein and Dr. Frankenstein all had daydreams, and went on to make great accomplishments.
In 1991, Doc traveled to August 12, 1927 to witness the Diamond Jubilee of the phonograph. He had Thomas Edison sign a giant light bulb, and filmed this moment for his "Doc on the March" segment of a video which would be shown at the Institute of Future Technology.
Behind the scenes
- Doc's portraits are of Isaac Newton, Benjamin Franklin, Thomas Edison and Albert Einstein, each of whom can be said to contribute to his development of the DeLorean time machine in the form of physics, conservation of charge, electrical invention and the space-time continuum.
