My Principal Business Is Giving Commercial Value

Radio Is Just A Fashion Contrivance That Will Soon Die Out. It Is Obvious That There Never Will Be Invented A Proper Receiver!

Results! Why, Man, I Have Gotten A Lot Of Results. I Know Several Thousand Things That Won't Work.

Of The 200 Light Bulbs That Didn't Work, Every Failure Told Me Something That I Was Able To Incorporate Into The Next Attempt.

I Never Did Anything Worth Doing Entirely By Accident. . . Almost None Of My Inventions Came About Totally By Accident. They Were Achieved By Having Trained Myself To Endure And Tolerate Hard Work.

The Dove Is My Emblem.
