[78-L] earliest recorded fon call

[James Tennyson]

I think the Telescribe was a combination of the two technologies. Pictures I 
have seen of it  in use have a box about six inches square upon which one 
set the telephone receiver...remember this was in the day of the candlestick 
telephone. One spoke into the telephone transmitter as usual and one 
listened by means of a small earphone which was attached to the unit.  The 
control box  was  attached another unit which  was attached to the acoustic 
recorder of the Ediphone. I presume the main unit consisted of a sensitive 
carbon microphone..(.somewhat like the Acousticon..the first electronic 
hearing aid )   the earpiece for the one making the call and an  earphone 
like unit which attached the dictating machine. There would of course be no 
electronic amplification, merely the volume provided by the microphone and 
it's battery.   At least this is what I suspect. There is the possibility 
that the unit attached to the dictating machine could have been a magnetic 
recorder,that is to say the diaphragm of the earphone could have been 
connected to a recording stylus, but I somehow doubt it, and the article 
I've linked below would seem to support my suspicion .    I've seen a 
publicity pic of Thomas Edison using the device at his desk in the library 
at West Orange.
If this link works it's the New York Times article about the introduction of 
the device.

Would this have been an acoustic device, or (!) electrical (sensed by a 
coil
at the phone)?
