Johann Philipp Reis

Johann Philipp Reis (German: [ʁaɪs] ; 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.

Germany Federal parliamentary republic in central-western Europe

Germany, officially the Federal Republic of Germany is a country in Central and Western Europe, lying between the Baltic and North Seas to the north and the Alps, Lake Constance and the High Rhine to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

Telephone Telecommunications device

A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user.

Reis telephone 19th-century musical telephone

The Reis telephone was an invention named after Philipp Reis of a telephonelike device he constructed. Reis's first successful work is dated to October 1861.

Reis' home in Friedrichsdorf, now a museum

Reis was born in Gelnhausen, Germany, the son of Marie Katharine (Glöckner) and Karl Sigismund Reis, a master baker. [1] [2] His father belonged to the Evangelical Lutheran church. [3] Reis's mother died while he was an infant, and he was raised by his paternal grandmother, a well-read, intelligent woman. At the age of six Reis was sent to the common school of his home town of Gelnhausen. Here his talents attracted the notice of his instructors, who advised his father to extend his education at a higher college. His father died before Reis was ten years old. His grandmother and guardians placed him at Garnier's Institute, in Friedrichsdorf, where he showed a taste for languages, and acquired both French and English, as well as a stock of miscellaneous information from the library. [4]

Gelnhausen Place in Hesse, Germany

Gelnhausen is a town and the capital of the Main-Kinzig-Kreis, in Hesse, Germany. It is located approximately 40 kilometers east of Frankfurt am Main, between the Vogelsberg mountains and the Spessart range at the river Kinzig. It is one of the eleven towns in the district. Gelnhausen has around 22,000 inhabitants.

German Confederation association of German states from 1815 to 1866

The German Confederation was an association of 39 German-speaking states in Central Europe, created by the Congress of Vienna in 1815 to coordinate the economies of separate German-speaking countries and to replace the former Holy Roman Empire, which had been dissolved in 1806. The German Confederation excluded German-speaking lands in the eastern portion of the Kingdom of Prussia, the German cantons of Switzerland, and the French region of Alsace, which was predominantly German speaking.

Friedrichsdorf Place in Hesse, Germany

Friedrichsdorf is a town of the Hochtaunuskreis, some 20 km (12 mi) north of Frankfurt am Main in Hesse, Germany.

At the end of his fourteenth year, Reis was accepted to a Hassel Institute, at Frankfurt am Main, where he learned Latin and Italian. A love of science became apparent, and his guardians were recommended to send him to the Polytechnic School of Karlsruhe. His uncle wished him to become a merchant, and on March 1, 1850, Reis was apprenticed as a paints dealer in the establishment of J. F. Beyerbach, of Frankfurt, against his will. He told his uncle that he would learn the business chosen for him, but would continue his preferred studies as he could. [4]

Frankfurt Place in Hesse, Germany

Frankfurt is a metropolis and the largest city of the German federal state of Hesse, and its 746,878 (2017) inhabitants make it the fifth-largest city in Germany, after Berlin, Hamburg, Munich, and Cologne. On the River Main, it forms a continuous conurbation with the neighbouring city of Offenbach am Main, and its urban area has a population of 2.3 million. The city is at the centre of the larger Rhine-Main Metropolitan Region, which has a population of 5.5 million and is Germany's second-largest metropolitan region after the Rhine-Ruhr Region. Since the enlargement of the European Union in 2013, the geographic centre of the EU is about 40 km (25 mi) to the east of Frankfurt's central business district. Like France and Franconia, the city is named after the Franks. Frankfurt is the largest city in the Rhine Franconian dialect area.

Karlsruhe Place in Baden-Württemberg, Germany

Karlsruhe is the second-largest city of the German federal state of Baden-Württemberg after its capital of Stuttgart, and its 309,999 (2016) inhabitants make it the 21st largest city of Germany. On the right bank of the Rhine, the city lies near the French-German border, between the Mannheim/Ludwigshafen conurbation to the north, and the Strasbourg/Kehl conurbation to the south. It is the largest city of Baden, a region named after Hohenbaden Castle in the city of Baden-Baden. Karlsruhe is also the largest city in the South Franconian dialect area, the only other larger city in that area being Heilbronn. The city is the seat of the Federal Constitutional Court (Bundesverfassungsgericht), as well as of the Federal Court of Justice (Bundesgerichtshof) and the Public Prosecutor General of the Federal Court of Justice.

By diligent service he won the esteem of Beyerbach, and devoted his leisure to self-improvement, taking private lessons in mathematics and physics and attending the lectures of Professor R. Bottger on mechanics at the Trade School. When his apprenticeship ended, Reis attended the Institute of Dr. Poppe, in Frankfurt. As neither history nor geography was taught there, several of the students agreed to instruct each other in these subjects. Reis undertook geography, and believed he had found his true vocation in the art of teaching. He also became a member of the Physical Society of Frankfurt. [4]

Mathematics Field of study concerning quantity, patterns and change

Mathematics includes the study of such topics as quantity, structure (algebra), space (geometry), and change. It has no generally accepted definition.

Physics Study of the fundamental properties of matter and energy

Physics is the natural science that studies matter, its motion and behavior through space and time, and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.

In 1855, he completed his year of military service at Kassel, then returned to Frankfurt to qualify as a teacher of mathematics and science by means of private study and public lectures. His intention was to finish his training at the University of Heidelberg, but in the spring of 1858 he visited his old friend and master, Hofrath Garnier, who offered him a post in Garnier's Institute. [4]

Kassel Place in Hesse, Germany

Kassel is a city located on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 200,507 inhabitants in December 2015. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site. Kassel is also known for the documenta exhibitions of contemporary art. Kassel has a public university with 25,000 students (2018) and a multicultural population.

On 14 September 1859, Reis married, and shortly after he moved to Friedrichsdorf, to begin his new career as a teacher.

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. [4]

<i>Annalen der Physik</i> German physics journal

Annalen der Physik is one of the oldest scientific journals on physics and has been published since 1799. The journal publishes original, peer-reviewed papers in the areas of experimental, theoretical, applied, and mathematical physics and related areas. The current editor-in-chief is Stefan Hildebrandt. Prior to 2008, its ISO 4 abbreviation was Ann. Phys. (Leipzig), and after 2008 Ann. Phys. (Berl.).

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. [5] 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." [4]

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. [6] 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. [5]

Previous experimenters

Reis monument in Gelnhausen: In 1878 European scientists declared Reis to be the telephone's inventor

Since the invention of the telephone, attention has been called to the fact that, in 1854, M. Charles Bourseul, a French telegraphist, had conceived a plan for conveying sounds and even speech by electricity:

Suppose that a man speaks near a movable disc sufficiently flexible to lose none of the vibrations of the voice; that this disc alternately makes and breaks the currents from a battery: you may have at a distance another disc which will simultaneously execute the same vibrations. …It is certain that, in a more or less distant future, speech will be transmitted by electricity. I have made experiments in this direction; they are delicate and demand time and patience, but the approximations obtained promise a favourable result.[ citation needed ]

Bourseul deserves the credit of being perhaps the first to devise an electric telephone and try to make it; but Reis deserves the honor of first realising the idea as a device to transmit and receive sounds electrically.

Bourseul's idea seems to have attracted little notice at the time, and was soon forgotten. Even the Count du Moncel, who was ever ready to welcome a promising invention, evidently regarded it as a fantastic notion. It is very doubtful Reis had ever heard of it. Reis was led to conceive a similar apparatus by a study of the mechanism of the human ear, which he knew contained a membrane which vibrated due to sound waves, and communicated its vibrations through the hammer-bone behind it to the auditory nerve. It therefore occurred to him, if he made a diaphragm to imitate this membrane and caused it, by vibrating, to make and break the circuit of an electric current, he would be able through the magnetic power of the interrupted current to reproduce the original sounds at a distance.

During 1837-38 Professor Page of Massachusetts had discovered that a needle or thin bar of iron, placed in the hollow of a coil or bobbin of insulated wire, would emit an audible 'tick' at each interruption of a current, flowing in the coil, and if these separate ticks followed each other fast enough, by a rapid interruption of the current, they would run together into a continuous hum, to which he gave the name galvanic music. He also found that the pitch of this note corresponded to the rate of the current's interruption. These faint sounds were due to magnetostriction. From these and other discoveries by Noad, Wertheim, Marrian, and others, Reis knew that if the current which had been interrupted by his vibrating diaphragm were conveyed to a distance by wires and then passed through a coil like that of Page's, the iron needle would emit notes like those which had caused the oscillation of the transmitting diaphragm. Acting on this knowledge, he constructed his rudimentary telephone. Reis' prototype is now in the museum of the Reichs Post-Amt, Berlin.

Shortcomings

Another of his early transmitters was a rough model of the human ear, carved in oak, and provided with a drum which actuated a bent and pivoted lever of platinum, making it open and close a springy contact of platinum foil in the metallic circuit of the current. He devised some ten or twelve different forms, each an improvement on its predecessors, which transmitted music fairly well, and even a word or two of speech with more or less fidelity.

The discovery of the microphone by Professor Hughes has demonstrated the reason of this failure. Reis' transmitter was based on interrupting the current, and the spring was intended to close the contact after it had been opened by the shock of a vibration. So long as the sound was a musical tone it proved efficient, for a musical tone is a regular succession of vibrations. The vibrations of speech are irregular and complicated, and in order to transmit them the current has to be varied in strength without being altogether broken. The waves excited in the air by the voice should merely produce corresponding waves in the current. In short, the current ought to undulate in sympathy with the oscillations of the air. The Reis phone was poor at transmitting articulated speech, but was able to convey the pitch of the sound.

It appears from the report of Herr von Legat, an inspector with the Royal Prussian Telegraphs, which was published in 1862, Reis was quite aware of this principle, but his instrument was not well adapted to apply it. No doubt the platinum contacts he employed in the transmitter behaved to some extent as a crude metal microphone, and hence a few words, especially familiar or expected ones, could be transmitted and distinguished at the other end of the line. If Reis' phone was adjusted so the contact points made a "loose metallic contact", they would function much like the later telephone invented by Berliner or the Hughes microphone, one form of which had iron nails in loose contact. Thus the Reis phone worked best for speech when it was slightly out of adjustment.

A history of the telephone from 1910 records that, "In the course of the Dolbear lawsuit, a Reis machine was brought into court, and created much amusement. It was able to squeak, but not to speak. Experts and professors wrestled with it in vain. It refused to transmit one intelligible sentence. ‘It can speak, but it won't,’ explained one of Dolbear's lawyers." It is now generally known that while a Reis machine, when clogged and out of order, would transmit a word or two in an imperfect way, it was built on the wrong lines. It was no more a telephone than a wagon is a sleigh, even though it is possible to chain the wheels and make them slide for a foot or two. Said Judge Lowell, in rendering his famous decision:

A century of Reis would never have produced a speaking telephone by mere improvement of construction. It was left for Bell to discover that the failure was due not to workmanship but to the principle which was adopted as the basis of what had to be done. …Bell discovered a new art—that of transmitting speech by electricity, and his claim is not as broad as his invention. …To follow Reis is to fail; but to follow Bell is to succeed. [7]

Reis does not seem to have realised the importance of not entirely breaking the circuit of the current; at all events, his metal spring was not practical for this, for it allowed the metal contacts to jolt too far apart, and thus interrupt the electric current.

His experiments were made in a little workshop behind his home at Friedrichsdorf; and wires were run from it to an upper chamber. Another line was erected between the physical cabinet at Garnier's Institute across the playground to one of the classrooms, and there was a tradition in the school that the boys were afraid of creating an uproar in the room for fear that Philipp Reis would hear them with his "telephon".

Publication

Reis' new invention was articulated in a lecture before the Physical Society of Frankfurt on 26 October 1861, and a description, written by himself for Jahresbericht a month or two later. It created a good deal of scientific excitement in Germany; models of it were sent abroad, to London, Dublin, Tiflis, and other places. It became a subject for popular lectures, and an article for scientific cabinets.

Reis obtained brief renown, but rejection soon set in. The Physical Society of Frankfurt turned its back on the apparatus which had given it lustre. Reis resigned in 1867, but the Free German Institute of Frankfurt, which elected him as an honorary member, also slighted the instrument as a mere "philosophical toy".

Reis believed in his invention, even if no one else did; and had he been encouraged by his peers from the beginning he might have perfected it. He was already stricken with tuberculosis, however. After Reis gave a lecture on the telephone at Gießen in 1854, Poggendorff, who was present, invited him to send a description of his instrument to the Annalen. Reis, it is said, replied: "Ich danke Ihnen sehr, Herr Professor, aber es ist zu spät. Jetzt will ich ihn nicht schicken. Mein Apparat wird ohne Beschreibung in den Annalen bekannt werden" ("Thank you very much, Professor, but it is too late. Now I do not want to send it. My apparatus will become known without any description in the Annalen.")

Final days

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.

In his Curriculum Vitae he wrote:

As I look back upon my life I call indeed say with the Holy Scriptures that it has been "labour and sorrow." But I have also to thank the Lord that He has given me His blessing in my calling and in my family, and has bestowed more good upon me than I have known how to ask of Him. The Lord has helped hitherto; He will help yet further.

Philipp Reis was buried in the cemetery of Friedrichsdorf, and in 1878, after the introduction of the electric telephone, the members of the Physical Society of Frankfurt erected an obelisk of red sandstone bearing a medallion portrait over his grave. [8]

In 1878, four years after his death and two years after Bell received his first telephone patent, European scientists dedicated a monument to Philip Reis as the inventor of the telephone.

Documents of 1947 in London's Science Museum later showed that after their technical adjustments, engineers from the British firm Standard Telephones and Cables (STC) found Reis' telephone dating from 1863 could transmit and "reproduce speech of good quality, but of low efficiency".

Sir Frank Gill, then chairman of STC, ordered the tests to be kept secret, as STC was then negotiating with AT&T, which had evolved from the Bell Telephone Company, created by Alexander Graham Bell. Professor Bell was generally accepted as having invented the telephone and Gill thought that evidence to the contrary might disrupt the ongoing negotiations.

Johann-Philipp-Reis Preis (Award)

The VDE (the German electrical engineering association), Deutsche Telekom and the cities of Friedrichsdorf and Gelnhausen biannually present the Johann-Philipp-Reis Preis (prize) to scientists for "....distinguished scientific achievements in the area of communication technology".

Telephone invention controversies

Besides Reis and Bell, many others claimed to have invented the telephone. The result was the Gray-Bell telephone controversy, one of the United States' longest running patent interference cases, involving Bell, Thomas Alva Edison, Elisha Gray, Emil Berliner, Amos Dolbear, J. W. McDonagh, G. B. Richmond, W. L. Voeker, J. H. Irwin, and Francis Blake Jr. The case started in 1878 and was not finalised until February 27, 1901. Bell and the Bell Telephone Company triumphed in this crucial decision, as well as every one of the over 600 other court decisions related to the invention of the telephone. The Bell Telephone Company never lost a case that had proceeded to a final trial stage. [9]

Another controversy arose over a century later when the U.S. Congress passed a resolution in 2002 recognizing Italian-American Antonio Meucci's contributions in the invention of the telephone (not for the invention of the telephone), a declaration that bore no legal or other standing at the United States Patent and Trademark Office (USPTO). Canada's Parliament quickly followed with a tit-for-tat declaration, which clarified: "....that Alexander Graham Bell of Brantford, Ont., and Baddeck, N.S., [was] the inventor of the telephone." [10] Prior to his death, Meucci had lost his only concluded Federal lawsuit trial related to the telephone's invention.

Bell's telephone patent was upheld in numerous court decisions.

Nathan Stubblefield American radio pioneer

Nathan Beverly Stubblefield, self-described "practical farmer, fruit grower and electrician", was an American inventor best known for his wireless telephone work. He received widespread attention in early 1902 when he gave a series of public demonstrations of a battery-operated wireless telephone, which could be transported to different locations and used on mobile platforms such as boats. While this initial design employed conduction, in 1908 he received a U.S. patent for a wireless telephone system that used magnetic induction. However, he was ultimately unsuccessful in commercializing his inventions. He later went into seclusion, and died alone in 1928.

David Edward Hughes, was a British-American inventor, practical experimenter, and professor of music known for his work on the printing telegraph and the microphone. He is generally considered to have been born in London but his family moved around that time so he may have been born in Corwen, Wales. His family moved to the U.S. while he was a child and he became a professor of music in Kentucky. In 1855 he patented a printing telegraph. He moved back to London in 1857 and further pursued experimentation and invention, coming up with an improved carbon microphone in 1878. In 1879 he identified what seemed to be a new phenomenon during his experiments: sparking in one device could be heard in a separate portable microphone apparatus he had set up. It was most probably radio transmissions but this was nine years before electromagnetic radiation was a proven concept and Hughes was convinced by others that his discovery was simply electromagnetic induction.

History of the telephone aspect of history relating to telephones

This history of the telephone chronicles the development of the electrical telephone, and includes a brief review of its predecessors.

Acoustic telegraphy was a name for various methods of multiplexing telegraph messages simultaneously over a single telegraph wire by using different audio frequencies or channels for each message. A telegrapher used a conventional Morse key to tap out the message in Morse code. The key pulses were transmitted as pulses of a specific audio frequency. At the receiving end a device tuned to the same frequency resonated to the pulses but not to others on the same wire.

The Telephone Cases, 126 U.S. 1 (1888), were a series of U.S. court cases in the 1870s and 1880s related to the invention of the telephone, which culminated in the 1888 decision of the United States Supreme Court upholding the priority of the patents belonging to Alexander Graham Bell. Those telephone patents were relied on by the American Bell Telephone Company and the Bell System—although they had also acquired critical microphone patents from Emile Berliner.

Ernst Walter Ruhmer was a German physicist. He was best known for investigating practical applications making use of the light-sensitivity properties of selenium, which he employed in developing wireless telephony using line-of-sight optical transmissions, sound-on-film audio recording, and television transmissions over wires.
