Did Alexander Graham Bell Steal The Telephone Patent? A new book claims Alexander Graham Bell stole the telephone from Elisha Gray, despite all the evidence against that theory.
The popular belief was that Bell arrived at the patent office an hour or two before his rival Elisha Gray, and that Gray lost his rights to the telephone as a result. That did not happen, according to Evenson. Alexander Graham Bell's Telephone Patent Drawing, 1876 The master telephone patent, 174465, granted to Bell, March 7, 1876
Shulman claims that the drawing of a liquid transmitter is strikingly similar to the earlier drawing in Elisha Gray’s patent caveat. Shulman’s conclusion is clear: Bell saw the caveat and copied the idea into his notebook. Bell subsequently built the liquid transmitter, which worked, and the rest is history.
His Western Electric company was a major supplier to the telegraph company Western Union. In 1874, Bell was in competition with Elisha Gray to be the first to invent the practical harmonic telegraph. Excerpts from Elisha Gray's patent caveat of February 14 and Alexander Graham Bell's lab notebook entry of March 8, demonstrating similarities.
Mr. Shulman sees a similarity between Gray's patent drawing and Bell's later sketch in his notebook and that is proof that Bell stole the idea of the liquid transmitter.
Bell's background and use of liquid transmitters. The theory that Alexander Graham Bell stole the idea of the telephone rests on the similarity between drawings of liquid transmitters in his lab notebook of March 1876 to those of Gray's patent caveat of the previous month.
Of course, this happened two days before his famous line calling to Watson. So, the secret is it looks like Bell plagiarized the successful design for a telephone from his rival Elisha Gray; and I go to great lengths to unravel what turns out to be quite a twisted tale about how that might have happened.
Answer. Alexander Graham Bell is credited with being the inventor of the telephone since his patent and demonstrations for an apparatus designed for “transmitting vocal or other sounds telegraphically… causing electrical undulations” were successful. First Bell Telephone, June 1875.
Western UnionWithin a couple of years Western Union boss William Orton had realized his mistake, but by that time Bell had already cottoned on to the fact that he might be on to a good thing: Bell Telephone was raking in the cash. The only answer for Western Union was to try and come up with something better.
In 1899, Gray moved to Boston where he continued inventing. One of his projects was to develop an underwater signaling device to transmit messages to ships. One such signaling device was tested on December 31, 1900. Three weeks later, on January 21, 1901, Gray died from a heart attack in Newtonville, Massachusetts.
Meucci devised an electromagnetic telephone as a way of connecting his second-floor bedroom to his basement laboratory, and thus being able to communicate with his wife.
Episode Info Alexander Graham Bell steals the original design for the telephone from Elisha Gray; Thomas Edison tries to create a movie-making monopoly.
18 patentsWhile there's some controversy over whether Bell was the true pioneer of the telephone, he secured exclusive rights to the technology and launched the Bell Telephone Company in 1877. Ultimately, the talented scientist held more than 18 patents for his inventions and work in communications.
In 2002, the U.S. House of Representatives passed Resolution 269, "Sense of the House Honoring the Life and Achievements of 19th Century Italian-American Inventor Antonio Meucci." Congressman Vito Fossella who sponsored the bill told the press, "Antonio Meucci was a man of vision whose enormous talents led to the ...
While Italian innovator Antonio Meucci (pictured at left) is credited with inventing the first basic phone in 1849, and Frenchman Charles Bourseul devised a phone in 1854, Alexander Graham Bell won the first U.S. patent for the device in 1876.
The first telephone had two parts: a transmitter and a receiver. The transmitter comprised three parts—a drumlike device (a cylinder with a covered end), a needle, and a battery. The covered end of the drumlike device was attached to the needle.
He came to the U.S as a teacher of the deaf, and conceived the idea of "electronic speech" while visiting his hearing-impaired mother in Canada. This led him to invent the microphone and later the "electrical speech machine" -- his name for the first telephone.

The first U.S. patent Issued to Samuel Hopkins for a process of making potash, an ingredient used in fertilizer. President George Washington signed the first patent.
His first invention came at the age of 12 while living in Scotland. It was a device with rotating paddles and sets of brushes that helped to de-husk wheat. 9 – Bell invented the telephone in 1874, at the age of 27. His father Melville started commercializing the invention in Canada in 1878.
Alexander Graham Bell was a professor of elocution at Boston University and tutor of deaf children. He had begun electrical experiments in Scotland in 1867 and, after emigrating to Boston, pursued research into a method of telegraphy that could transmit multiple messages over a single wire simultaneously, a so-called "harmonic telegraph". Bell formed a partnership with two of his students' parents, including prominent Boston lawyer Gardiner Hubbard, to help fund his research in exchange for shares of any future profits. He experimented with many different possible transmitters and receivers from 1872 to 1876, created numerous drawings of liquid transmitters, and obtained a patent in 1875 for a primitive fax machine using liquid transmitters, which appear in the published drawings in the U.S. Patent Office.
In a letter of March 2, 1877, Bell admitted to Gray that he was aware Gray's caveat "had something to do with the vibration of a wire in water [the variable resistance breakthrough that made the telephone practical] — and therefore conflicted with my patent.".
In violation of Patent Office rules, he told Bailey about Gray's caveat and told his superiors that Bell's patent application had arrived first. During Bell's visit to Washington, "Prof. Bell was with me an hour when I showed him the drawing [of Gray's caveat] and explained Gray's methods to him.".
In 1875, Bell filed a patent application for a primitive fax machine which included drawings of multiple liquid transmitters and the Patent Office granted his application as Patent No. 161739 in April, 1875 —ten months before Gray filed his telephone caveat.
In the winter of 1872-73, after emigrating to Boston, Bell became a professor of elocution at Boston University. He continued research into phonetics and resumed the electrical experiments he had begun in Bath and London towards improving the telegraph. Bell replicated and enlarged upon Helmholtz's tuning fork sounder experiments (see Fig. 3 ). These experiments involved running an electric current through a tuning fork attached to a wire that dipped in liquid as the fork vibrated. The tone of the fork was then replicated in another fork hooked up into the circuit. These experiments, with a vibrating wire touching a liquid, anticipated the liquid transmitter of Bell's telephone in March, 1876 three years later. (Compare Fig. 3 and Fig. 7, for example.)
Fig. 2. Bell was aided in his telephone experiments by a thorough understanding of how human speech works. At the age of 19, he did primary research into the production of vowel sounds that was recognized as novel by leading philologists.
Bell had an important advantage over other inventors trying to develop a talking machine: he had been trained in phonetics and had a deep understanding of how human speech is produced by the mouth and how the ear processes sound. While electricians such as Reis, Gray and Edison used make-or-break currents (like a buzzer) in their attempts, Bell understood acoustics and wave theory and applied this knowledge to analogous work in his electrical experiments.
Elisha Gray's Patent Caveat Filed on February 14, 1876. To all whom it may concern: Be it known that I, Elisha Gray, of Chicago, in the County of Cook, and State of Illinois, have invented a new art of transmitting vocal sounds telegraphically, of which the following is a specification.
He studied electricity at Oberlin College. In 1867, Gray received his first patent for an improved telegraph relay. During his lifetime, Elisha Gray was granted over seventy patents for his inventions, including many important innovations in electricity.
Mary Bellis covered inventions and inventors for ThoughtCo for 18 years. She is known for her independent films and documentaries, including one about Alexander Graham Bell.
On February 14, 1876, Alexander Graham Bell's telephone patent application entitled "Improvement in Telegraphy" was filed at the USPTO by Bell's attorney Marcellus Bailey. Elisha Gray's attorney filed a caveat for a telephone just a few hours later entitled "Transmitting Vocal Sounds Telegraphically."
Elisha Gray was an American inventor who contested the invention of the telephone with Alexander Graham Bell. Elisha Gray invented a version of the telephone in his laboratory in Highland Park, Illinois.
Owing to this construction, the resistance varies constantly in response to the vibrations of the diaphragm, which, although irregular, not only in their amplitude, but in rapidity, are nevertheless transmitted, and can, consequently, be transmitted through a single rod, which could not be done with a positive make and break of the circuit employed, or where contact points are used.
At the church, on December 29, 1874 , Gray gave the first public demonstration of his invention for transmitting musical tones and transmitted "familiar melodies through telegraph wire" according to a newspaper announcement.
On March 3, Wilber approved Bell's application and on March 7, 1876 , U.S. Patent 174,465 was published by the U.S. Patent Office .
In 1887 Gray invented the telautograph, a device that could remotely transmit handwriting through telegraph systems. Gray was granted several patents for these pioneer fax machines, and the Gray National Telautograph Company was chartered in 1888 and continued in business as The Telautograph Corporation for many years; after a series of mergers it was finally absorbed by Xerox in the 1990s. Gray's telautograph machines were used by banks for signing documents at a distance and by the military for sending written commands during gun tests when the deafening noise from the guns made spoken orders on the telephone impractical. The machines were also used at train stations for schedule changes.

According to Evenson, during the weekend of February 12–14, 1876, before either caveat or application had been filed in the patent office, Bell's lawyer learned about the liquid transmitter idea in Gray's caveat that would be filed early Monday morning February 14. Bell's lawyer then added seven sentences describing the liquid transmitter and a variable resistance claim to Bell's draft application. After the lawyer's clerk recopied the draft as a finished patent application, Bell's lawyer hand-delivered the finished application to the patent office just before noon Monday, a few hours after Gray's caveat was delivered by Gray's lawyer. Bell's lawyer requested that Bell's application be immediately recorded and hand-delivered to the examiner on Monday so that later Bell could claim it had arrived first. Bell was in Boston at this time and was not aware that his application had been filed.
Taylor, an Oberlin physics department head, began writing a Gray biography, but the book was never finished because of Taylor's accidental death in July 1948. Dr Taylor's unfinished manuscript is in the College Archives at Oberlin College. This article needs additional citations for verification.
Gray conceived of a primitive closed-circuit television system that he called the " telephone ". Pictures would be focused on an array of selenium cells and signals from the selenium cells would be transmitted to a distant station on separate wires.
On Valentine’s Day 1876 Bell and Gray each submitted an application to the U.S. Patent Office for a device to transmit the human voice over a wire—in other words, a telephone. On March 7, 1876, after reviewing their competing applications, the patent office awarded a patent to Bell, saying his papers had arrived two hours before Gray’s.
Two books have revived the controversy with a vengeance. The Telephone Patent Conspiracy by A. Edward Evenson, published in 2001, says Gray may have filed his application with the patent office before Bell, but a clerk with a drinking problem was bribed by Bell’s wealthy backers—without Bell’s knowledge—to change the order of the filings and give Bell the victory.
The courts decided priority in favor of Bell and the telephone company he founded. In addition to being constructed differently from the transmitter described and pictured in Gray's caveat, Bell's working liquid transmitter of March 10, 1876 operated in a way that is in fact described in Bell's original patent application, but not in Gray's caveat.

The theory that Alexander Graham Bell stole the idea of the telephone rests on the similarity between drawings of liquid transmitters in his lab notebook of March 1876 to those of Gray's patent caveat of the previous month. However, there is extensive evidence that Bell had been using liquid transmitters in various experiments for over three years before that time. In 1875, Bell filed a patent application for a primitive fax machine which included drawings of multiple liquid t…
In a November 2015 episode of Drunk History, this controversy was reenacted with Martin Starr as Alexander Graham Bell, Henry Winkler as Wilber, and Jason Ritter as Elisha Gray. This reenactment claimed that Alexander Graham Bell definitely stole the necessary knowledge from the examiner Wilber, and that Graham Bell was a villain who stole all of the glory whilst Gray was the real inventor. None of the vagaries of this controversy were discussed in any depth.
