I find out what the world needs, then I proceed to invent. My main purpose in life is to make money so that I can afford to go on creating more inventions.

Someday man will harness the rise and fall of the tides, imprison the power of the sun, and release atomic power.

I believe that the science of chemistry alone almost proves the existence of an intelligent creator.

I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.

Of all my inventions, I liked the phonograph best. Life's most soothing things are sweet music and a child's goodnight.

I never did anything worth doing entirely by accident and none of my inventions came about totally by accident. They came about by hard work.
