----- as Patrick Feaster has very convincingly argued (Spring 2007, ARSC),

Discovery of the Phonograph Principle," ARSC Journal 38:1 (Spring 2007), 10-43.
I argue that, contrary to what you may have read elsewhere, the phonograph
actually originated in 1877 as a byproduct of Thomas Edison's unsuccessful
plan to build a "keyboard talking telegraph," an instrument that would have
allowed users to "play" individual speech sounds over a telephone line
rather than speaking them into a mouthpiece."
If you read his article, you would have to work hard to argue against his
conclusions."

Patrick has very kindly sent me a pdf version of his 2007article on
Speech Acoustics, and it is indeed a wonderful overview of that annus
mirabilis (1877). I would not so much argue "against" his conclusions, as to, ahem,
amplify upon them. Much thanks, PF.
The rhetorical device on which this re-interpretation hangs is a cited
comment that TAE made in 1889, that a "reliable account" had not yet (then)
been given of the discovery of the phonograph principle. One wonders what
exactly would pass such a test, in his (TAE's) eyes? And for what reason
would he himself, in his many interviews (1877-1880), leave out Patrick's
conclusion that the idea was (strictly?) a result of his work on the "keyboard
telegraph"? TAE certainly had many opportunities, then and later, to
correct the "record" and preserve for posterity the 'true' story. But he never
did this (apparently). Is there thus some "secret" (or unknown) version?
Patrick mentions an interesting US patent, 474,230 (which contains
material that was preserved (or paralleled) in Brit pat 2909). But 474,230 was
only part of 2909, and the US application was "divided" (in 1877), finally
yielding also 474,231 and 474,232. The former was executed on July 9th.
Interestingly, it took 15 years to nurse the American version(s) thru the patent
system, and those 3 were not granted until 1892. It would be very helpful
to acquire the contents of their Patent Wrappers (contents) from the
National Archives, as the preserved correspondence and adjustments would reveal
what caused the conflicting issues (and long delay). Brit Pat 2909 had its
own share of problems for Edison, as it started out as a telephone patent
when it was filed, but was wrongheadedly used by Edison to introduce his
tinfoil phonograph (in England) during its period of application (fig. 29
added). Eventually (1882), this attempt was disavowed by him, and the
phonographic portion was removed. One could lose US protection if one filed for the
same patent in another country first, even as an afterthought in a different
patent. It was a fine art to get the procedures exactly correct. #2909's
belated use for protecting the phonograph was a lawyer's blunder, and
Edison himself admitted it could never be "made right" because of the Dec 24th
addition.
I do not know what year Edison first went to Washington DC, where
Scott's Phonoautograph (Koenig model) was on Display (and had been since 1866).
It is still there today, 145 years after it was bought for 500 francs. As
far as I recall, Edison never mentions, in real time, his view of it (visual
or in abstract thought), before 1877. I think he did see it during his Wash
trip in April of 1878, where he must have been surprised at how close
others (Scott & Koenig) had come to his "baby". But he and Scott were worlds
apart in their approach to sound; Scott had no interest in preserving
vertical vibrations, and no oscillations that were not distinctly visual, although
Edison would mention lateral recording in his famous patent, 200,521. And
no one was much interested in Thomas Young's work of 1806, which recorded
the vibrations, in wax, of a tuning fork stylus on a drum. Young could have
played back the first recorded sound - a tuning fork! Ironically, such a
device (diapason tracing) appears even on Scott's 1860 effort.
I see little doubt as to the origins of Edison's phonograph, as arising
directly from TAE's work with the telephone. Nor should one omit the
contextual influence of the telegraph and its various 'repeaters.' Telephones
were still quite expensive and could only be rented in 1877. One of Edison's
anticipated uses for his recorder was to save messages intended for
recipients who still did not own one - they could visit a central office and play
back what they missed (for a fee) when the call came in. This must have
seemed a good idea at the time, but it was also Edison's later insight that
people would never sit in a darkened room with strangers to watch flickering
lights.
Patrick says: "We do not possess any document in which Edison explains
the circumstances under which he thought his keyboard telephone might be
used, or what its practical benefits might be." And yet also: "Edison's
notebook entries of 26 May 1877 show that he was then already eager to build
both a speech recorder and a speech generator," So I am confused. Is there a
reason why this May 26th document was not quoted (in the article), regarding
such a 'recorder'? And what was the actual imagined method of "recording"?
It is a fascinating enterprise to fathom how things get invented
(logically) - we have the enormous advantage of hindsight, looking at the larger
"flow" of ideas, and of course, where things "end up." But I would even
argue that the phonograph was invented "too soon" - after all, it would be
another 10 years before the culture would figure out (and apply) what to do
with it.
I wish we knew more about the "Halloo" device (made by Batchelor?),
supposedly built before the first (rotating) tinfoil model. This "sliderule"
contraption of wood used paraffined paper, left over from telegraph and
condenser use. It was only pictured, in the Scientific American, a year later
(Aug 1878). Certainly by July 1877, Edison had absorbed (and said so) the
basic insight that the human voice, in its totality, could be saved like a
photograph, to be preserved and recreated after its subject had left the room.
I still like that pivotal July 18th date, as a defined Eureka moment. The
various experiments that attracted Edison's acoustic interest in 1877, in
retrospect, look like so many 'detours' until he got it right. But after
all, Scott's machine had been widely pictured AND published in many Physics
texts (USA, England, Germany, Italy), ever since 1860, and even at
International Expositions (e.g. 1862). Why did NO ONE get inspired by the device to
save and recreate sound from those carbonized tracings? It is one thing to
look forward in time, another to look back. In retrospect, we can agree with
the Wizard that all the savants in the world clearly overlooked how close
Scott had come. It was easy for Edison to say so, since he had won the
prize.
