English: Drawing of a typist transcribing dictation using an early wax cylinder phonograph. Although the phonograph was first invented by Thomas A. Edison, the source text says this was a machine called the 'G', invented by Alexander Graham Bell, Chichester A. Bell, and Sumner Tainter. The typist pumps the treadle with his foot, turning the cylinder to play back the recording, and listens to it using 'stethoscope' type earphones. Extra wax cylinders, and a funnel-like mouthpiece used to record dictation, are seen on the desk. Alterations to image: removed caption, which read, "The Gramophone used in transcribing". The device shown is technically not a gramophone, which was a disk recording device.
