Johann Philipp Reis (German: [ˈʀaɪs]; January 7, 1834 – January 14, 1874) was a self-taught German scientist and inventor.
In 1861, he constructed the first make-and-break telephone, today called the Reis 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.
Later, Reis continued his teaching and scientific studies, but his failing health had become a serious impediment. For several years it was only by the exercise of his strong will that he was able to carry on with his duties. His voice began to fail as his lung disease became more pronounced, and in the summer of 1873 he was obliged to forsake his tutoring duties for several weeks. An autumn vacation strengthened his hopes of recovery and he resumed his teaching, but it was to be the last flicker of his expiring flame. It was announced that he would show his new gravity-machine at a meeting of the Gesellschaft Deutscher Naturforscher und Ärzte (Society of German Scientists and Physicians) of Wiesbaden in September, but he was too ill to appear. In December he lay down and, after a long and painful illness, died at five o'clock in the afternoon of January 14, 1874.
