The Ediphone is a dictation machine invented by Thomas Edison for the recording and transcription of letters. Three machines would have completed the set: President Stoke is using the one that recorded messages onto a wax cylinder; a second machine (like the one on display) reproduced the message through headphones so it could be transcribed onto a typewriter; and a third machine shaved the outer layer of wax off the cylinder so it could be re-used.
