LISTENING TO RECORDINGS
September 25, 1940
Percy Grainger (left), noted composer, and Elmer O. Thompson, Philco Corpn., engineer who invented equipment for transcribing old phonograph cylinder records, are shown listening to recordings.
Mr. Grainger brought to the Library of Congress nearly 300 cylinder records of folk music which he had recorded nearly 40 years ago, and had kept unplayed.
Ordinary phonograph needles quickly wear out such records.
New apparatus, using electric eye device, does not damage the record,
and reproduces the music far more faithfully than tin horn phonographs
of past could do.
