Yes - thanks for posting the link, Stephan. I didn't know the article was available online, but I'm happy to learn it is.
One of the most interesting things that Feaster describes is the existence of TWO "eureka experiences" leading to Edison's discovery of the Phonograph. (These two separate experiences also account for two versions offered by Edison himself over the years.)
The first "eureka experience" was the buzzing of the telegraphic embosser, which led to Edison's conception of recreating sound/speech. Thus, sound
reproduction was conceived before recording.
The second "eureka experience" was the finger-pricking of the embossing needle, leading to Edison's conception of
recording sound/speech.
Since reproduction was envisioned before recording, Edison's initial efforts were directed toward making "synthetic speech" much as had been done by Faber and others. (Picture a fabricated human head with anatomically correct rubber tongue, movable jaw, palate, vocal cords, etc. A bellows would generate air flow and synthetic speech could be created - - although hardly intelligible!)
The second "eureka experience" - that of
recording sound (instead of synthesizing it), brought about the invention of the Phonograph. Edison would not need to create the words or letters, but could record the actual sound. From our perspective, the recording seems intuitive, but this aspect eluded several great inventive minds of the time; notably Alexander Graham Bell. He wrote to his father-in-law in March 18,1878,
"It is a most astonishing thing to me that I could possibly have let this invention slip through my fingers when I consider how my thoughts have been directed to this subject for so many years. So nearly did I come to the idea that I had stated again and again in my public lectures the fundamental principles of the Phonograph. In showing to an audience the tracings produced by the Phonautograph I had said if the motions indicated by the curves could be produced mechanically in any way the sounds would be audible...and yet in spite of this the thought never occurred to me to indent a substance and from the indentation to produce sound."
We are all products of our times, and think in ways we have been taught to think. Fascinating stuff.
