⭐ Core Definition: Elisha Gray

Elisha Gray (August 2, 1835 – January 21, 1901) was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois. Some recent authors have argued that Gray should be considered the true inventor of the telephone because Alexander Graham Bell allegedly stole the idea of the liquid transmitter from him. Although Gray had been using liquid transmitters in his telephone experiments for more than two years previously, Bell's telephone patent was upheld in numerous court decisions.

Gray is also considered to be the father of the modern music synthesizer, and was granted over 70 patents for his inventions. He was one of the founders of Graybar, purchasing a controlling interest in the company shortly after its inception.

👉 Elisha Gray in the context of Telecommunications

Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electrical or electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telephone, television, and radio.

Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics. Other early pioneers in electrical and electronic telecommunications include co-inventors of the telegraph Charles Wheatstone and Samuel Morse, numerous inventors and developers of the telephone including Antonio Meucci, Philipp Reis, Elisha Gray and Alexander Graham Bell, inventors of radio Edwin Armstrong and Lee de Forest, as well as inventors of television like Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth.

Elisha Gray in the context of Reis telephone

The Reis telephone was an early sound transmitting device, invented by Philipp Reis in 1857. Reis's first successful work is dated to October 1861. When properly set up, it would allow verbal communication via electronic signals. Many sources credit Reis as the inventor of the first telephone. Others point to the prior work of Antonio Meucci, or to later work of Elisha Gray or Alexander Graham Bell. However it is generally agreed that Reis coined the word telephon -- which has been Anglicised to telephone.

Elisha Gray in the context of Elisha Gray and Alexander Bell telephone controversy

The Elisha Gray and Alexander Graham Bell controversy concerns the question of whether Elisha Gray and Alexander Graham Bell invented the telephone independently. This issue is narrower than the question of who deserves credit for inventing the telephone, for which there are several claimants.

At issue are roles of each inventor's lawyers, the filing of patent documents, and allegations of theft.

Elisha Gray in the context of Graybar

Graybar Electric Company, Inc. is an American wholesale electrical, communications and data networking products distribution business, which also supplies related supply-chain management and logistics services. The company is based in Clayton, Missouri and is an employee-owned corporation.

Graybar was incorporated on December 11, 1925, as the successor company of the general electric supply business of the Western Electric Company, which was founded in 1869 in Cleveland, Ohio, by Elisha Gray and Enos M. Barton. The separation of product lines was intended to provide a separate identity from the telephone supply function of Western Electric to the Bell System, given its importance as the largest merchandiser of electrical apparatus and related equipment in the world in the 1920s.
