The Telephone
Reis imagined electricity could be propagated through space, as light can, without the aid of a material conductor, and he performed some experiments on the subject. The results were described in a paper, "On the Radiation of Electricity", which, in 1859, he mailed to Professor Poggendorff for insertion in the then well-known periodical, Annalen der Physik. The manuscript was rejected, to the great disappointment of the sensitive young teacher.
Reis, like Bell would later do, had studied the organs of ear and the idea of an apparatus for transmitting sound by means of electricity had floated on his mind for years. Inspired by his physics lessons he attacked the problem, and was rewarded with success. In 1860, he constructed the first prototype of a telephone, which could cover a distance of 100 meters. In 1862, he again tried to interest Poggendorff with an account of his "telephon", as he called it. His second offering was also rejected, like the first. The learned professor, it seems, regarded the transmission of speech by electricity as a chimera; Reis bitterly attributed the failure to his being "only a poor schoolmaster."
Reis had difficulty interesting people in Germany in his invention despite demonstrating it to (among others) Wilhelm von Legat, Inspector of the Royal Prussian Telegraph Corps in 1862. It aroused more interest in the United States In 1872, when Professor Vanderwyde demonstrated it in New York.
Prior to 1947, the Reis device was tested by the British company Standard Telephones and Cables (STC). The results also confirmed it could faintly transmit and receive speech. At the time STC was bidding for a contract with Alexander Graham Bell's American Telephone and Telegraph Company, and the results were covered up by STC's chairman Sir Frank Gill to maintain Bell's reputation.

Famous quotes containing the word telephone:
“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
“It is possible that the telephone has been responsible for more business inefficiency than any other agency except laudanum.... In the old days when you wanted to get in touch with a man you wrote a note, sprinkled it with sand, and gave it to a man on horseback. It probably was delivered within half an hour, depending on how big a lunch the horse had had. But in these busy days of rush-rush-rush, it is sometimes a week before you can catch your man on the telephone.”
—Robert Benchley (1889–1945)
