This set of pictures shows the Webster Chicago wire recorder (model 80-1) and related accessories, including a microphone, a collection of reels from different sources, and a case. This device belongs to the same group of electromagnetic wire recorders as the Minifon P55 and the MN-61 military recorder, which were both produced later than the Webster Chicago model. The use of reels of magnetized wire to record electric signals goes back to Valdemar Poulsen’s 1898 Telegraphon, an early electronic sound-recording device. A Webster Chicago wire recorder was used in 1950–51 by Albert Lord, a scholar of epic literature, to make recordings of Yugoslavian epic singers. These recordings are now part of the Milman Parry Collection of Oral Literature at Harvard University.

The video demonstrates the use of the Webster Chicago wire recorder (model 80-1).
