Note 4 — XIV

“I was singing to the mouthpiece of a telephone,” said Edison, “when the vibrations of my voice caused a fine steel point to pierce one of my fingers held just behind it. That set me to thinking. If I could record the motions of the point and send it over the same surface afterward, I saw no reason why the thing would not talk. I determined to make a machine that would work accurately, and gave my assistants the necessary instructions, telling them what I had discovered. That’s the whole story. The phonograph is the result of the pricking of a finger.”
