In 1860 Johann Philipp Reis was the first who produced a functioning electromagnetic device that could transmit musical notes, indistinct speech, and occasionally distinct speech by means of electric signals. Reis also introduced the term “telephon” for his device. The first sentence spoken on it was “Das Pferd frisst keinen Gurkensalat” (the horse doesn’t eat cucumber salad). In the Reis transmitter, a diaphragm was attached to a needle that pressed against a metal contact. This resembled the make-or-break design of Bourseul, although Reis used the term “molecular motion” (molekulare Bewegung) to describe the contact points of his transmitter.[3] The Reis transmitter was very difficult to operate, since the relative position of the needle and the contact were critical to the device’s operation. This can be called a “telephone”, since it did transmit voice sounds electrically over distance, but was hardly a commercially practical telephone in the modern sense, as it failed to reliably transmit a good copy of any supplied sound.
