Long before the issuing of a patent, on 07 March 1875, to Alexander Graham Bell, telephone invention began as Robert Hooke’s grassroots idea in 1667. It began the journey as a mechanical or acoustic device. To overcome its inherent distance and quality of sound limitations, many inventors contributed to its uplifting to an electrical device. In addition to Robert Hooke and Alexander Graham Bell, some of the notable names in the journey of telephone invention are (i) Antonio Meucci, (ii) Elisha Gray, (iv) Tivadar Puskás, and (v) Thomas Alva Edison.
Who did invent the telephone? When and how did it happen? Due to its immense importance, many of us are curious about the telephone’s invention. Contrary to common belief, it did not occur due to a single creative spark in the mind of a genius. Despite Alexander Graham Bell’s immense contribution to the telephone invention, many inventors deserve the credit. Over centuries, cumulative effects of bits and pieces of creative sparks have culminated into the telephone invention.
It began the journey in 1667 with Robert Hooke’s lovers’ telephone. It emerged as the outcome of reshaping and integrating available components like tin cans and string to get the communication job done from a distance done. This is a typical example of grassroots or frugal Innovation. But, unlike many other grassroots ideas, it did not get stunted. Instead, it kept progressing and ended in issuing a patent, on 07 March 1875, to Alexander Graham Bell for the invention of the telephone. Some of the great names credited for the telephone inventions are Robert Hooke, Antonio Meucci, Alexander Graham Bell, Elisha Gray, Tivadar Puskás, and Thomas Alva Edison. Like many other inventions, it also demanded a Flow of Ideas.
Telephone invention began with mechanical technology core:
Like many other great inventions, the telephone began the journey with mechanical technology core in recorded history. In 1667, Robert Hooke invented the string telephone. An extended wire conveyed sounds by mechanical vibrations of the string. Two tin cans, paper cups, or similarly shaped items are used for sending and receiving signals. They were connected to either end of a taut string or wire. Its ability to transmit speech by acoustic or mechanical means was limited by distance. However, the distance was greater than that of normal direct speech. Hence, it got popularity for transmitting speech and music over the vibrating string—giving birth to the telephone.
Reinvention of the mechanical telephone by electrical technology core:
Despite the popularity of the mechanical telephone, this invention was not scalable. Its diffusion was facing a barrier due to limited distance. Hence, the journey of overcoming the distance barrier began by reinventing telephone invention by changing the mechanical technology core with electrical means. Almost after 100 years of Hooke’s telephone invention, in 1753, Charles Morrison proposed the idea that electricity, instead of mechanical vibration, can be used to transmit messages. Subsequently, it took almost another 100 years to get Innocenzo Manzetti’s idea of a “speaking telegraph” (telephone) in 1844. Charles Bourseul’s memorandum followed it up on the principles of the telephone in 1854 in Paris.
After almost two hundred years since Hooke’s invention, activities around telephone reinvention got quite a bit of momentum. In 1854, Antonio Meucci took the telephone reinvention idea further by demonstrating an electric voice-operated device in New York. It was followed by Philipp Reis’s construction of the first speech-transmitting telephone in 1861. After almost ten years, in 1871, Antonio Meucci filed a patent caveat at the U.S. Patent Office for a device he named “Sound Telegraph”.
Alexander Graham Bell’s contribution:
In 1871, Bell started working on a multiple or harmonic telegraph device. This is a technique for telegraph transmission of several messages set to different frequencies. He spent long days and nights between 1873 and 1874, perfecting the harmonic telegraph. This experimentation created interest in him about another idea. This is about transmitting the human voice over electrical wires. However, this diversion started creating frustration among the benefactors of Bell’s telegraph work. Hence, benefactors hired Thomas Watson, a skilled electrician, to influence Bell to refocus on the harmonic telegraph. But as opposed to encouraging Bell to stay away from diversion, Watson started sharing Bell’s interest in implementing the ideas of transmitting human voice.
A great partnership with Bell being the idea man and Watson having the expertise to bring Bell’s ideas to reality formed and played a vital role in inventing the electric telephone. Subsequently, after years of work, on March 10, 1876, Bell made his first telephone call using his invention. On 30 January 1877, Bell received U.S. patent No. 186,787. This is the patent for the electromagnetic telephone using permanent magnets, iron diaphragms, and a call bell. However, upon the demonstration, he did not stop pursuing telephone invention. On July 9, 1877, he founded the Bell Telephone Company for commercially rolling out his invention. The Scientific American published the invention from Bell on 6 October 1877. Subsequently, World started witnessing the rollout of telephone services, installing exchanges in Berlin and Boston.
Controversy to telephone invention:
Among others, Elisha Gray is well regarded for his development of a telephone prototype in 1876. There are arguments that Gray should be considered the true inventor of the telephone among scholars. This controversy is based on the allegation that Alexander Graham Bell stole the idea of the liquid transmitter from Gray. Among others, in 1875, Thomas Edison experimented with acoustic telegraphy. In November of the same year, he built an electro-dynamic receiver; but he did not exploit it. For a carbon (graphite) transmitter, Edison filed for a patent on 27 April 1877. However, due to litigation, it took a long 15-year to get the patent on 3 May 1892. Edison also received a patent for a carbon granules transmitter in 1879.
Birth of telephone equipment making company: Western Electric
Upon purchasing shares of telegraph equipment-making business from George Shawk in 1872, Elisha Gray established Western Electric Manufacturing Company. Wester Electric played a pioneering role in improving, manufacturing, and commercializing telephone devices. However, Mr. Gray sold his interest in the company to Western Union in 1875. After losing the patent battle in 1879 to Bell Telephone Company, Western Union withdrew from the telephone market and let Bell acquire Western Electric in 1881.
Subsequently, it became an integral part of AT&T for most of its lifespan. It served as the primary equipment manufacturer, supplier, and purchasing agent for the Bell System from 1881 to 1984. Western Electric made contributions to many technological innovations, developments, and standardization for supporting the continued progression of telephone invention.
Reoccurring patterns in telephone invention:
The long journey of telephone invention offers us valuable lessons. Contrary to common belief, suddenly, the great invention does not show up, giving us a Eureka experience. Often, it takes the creative work of dozens of people over a prolonged period. Furthermore, often, great ideas emerge in primitive form. It requires subsequent advancement, even through the change of technology core, to unlock the potential.
Besides, like the telephone inventions, many great ideas get into controversy, particularly during the last mile. Hence, articulating ideas and filling patents are essential in managing the invention journey. Bell’s diversion from the passion for solving a problem gives us a valuable lesson—passion for perfection opens the door to inventing great ideas.
Furthermore, it’s a typical example of grassroots or frugal innovation. But, like many other grassroots innovations, Robert Hooke’s machinal phone, grassroots innovation, was not scalable. Hence, it could not diffuse deeper in society. Further inventive work continued to scale it up. Eventually, it led to reinventing the initial idea of the acoustic telephone by changing the mechanical technology core with electrical. Besides, the entrepreneurial activities of Mr. Bell and others underscore the importance of the involvement of inventors or fine-tuning the design and rolling out the invention as commercial innovation products.
By the way, since the formal recognition of the telephone invention in 1877, the advancement of the telephone has been progressing and diffusing deeper in society as progressive waves.
