We will make electricity so cheap that only the rich will burn candles.

I never once failed at making a light bulb. I just found out 99 ways not to make one.

There's a way to do it better - find it.

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.

I have always consistently opposed high-tension and alternating systems of electric lighting...not only on account of danger, but because of their general unreliability and unsuitability for any general system of distribution.

The thing I lose patience with the most is the clock. Its hands move too fast

My main purpose in life is to make money so I can afford to go on creating more inventions.
