Elisha Gray

GrayGray, Elisha
Elisha Gray, of Highland Park, Illinois (near Chicago) also devised a tone telegraph of this kind about the same time as La Cour.
Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois.

Bell Homestead National Historic Site

Bell HomesteadCharles James BellThomas Philip Henderson
Only a few months after receiving U.S. Patent No. 174465 at the beginning of March 1876, Bell conducted three important tests of his new invention and the telephone technology after returning to his parents' home at Melville House (now the Bell Homestead National Historic Site) for the summer.
The younger Bell conducted his earliest experiments in North America there, and later invented the telephone at the Homestead in July 1874.

Volta Prize

prix du Galvanisme
In 1880, Bell was awarded the French Volta Prize for his invention and with the money, founded the Volta Laboratory in Washington, where he continued experiments in communication, in medical research, and in techniques for teaching speech to the deaf, working with Helen Keller among others.
One of its most notable awards was made in 1880, when Alexander Graham Bell received the fourth edition of the Volta Prize for the invention of the telephone.

The Reis telephone was developed from 1857 on. Allegedly, the transmitter was difficult to operate, since the relative position of the needle and the contact were critical to the device's operation.

Goldbeater's skin

gold beater's skingoldbeaters skin
On July 1, 1875, he instructed Watson to build a receiver consisting of a stretched diaphragm or drum of goldbeater's skin with an armature of magnetized iron attached to its middle, and free to vibrate in front of the pole of an electromagnet in circuit with the line.
Alexander Graham Bell used a drum of goldbeater's skin with an armature of magnetised iron attached to its middle as a sound receiver (see Invention of the telephone).

Charles Bourseul

Bourseul, Charles
Charles Bourseul was a French telegraph engineer who proposed (but did not build) the first design of a "make-and-break" telephone in 1854. On the basis of this prototype, Meucci worked on more than 30 kinds of sound transmitting devices inspired by the telegraph model as did other pioneers of the telephone, such as Charles Bourseul, Philipp Reis, Innocenzo Manzetti and others. Meucci later claimed that he did not think about transmitting voice by using the principle of the telegraph "make-and-break" method, but he looked for a "continuous" solution that did not interrupt the electric current.

Telephone exchange

Additional inventions such as the call bell, central telephone exchange, common battery, ring tone, amplification, trunk lines, and wireless phones – at first cordless and then fully mobile – made the telephone the useful and widespread apparatus it is now.
As with the invention of the telephone itself, the honor of "first telephone exchange" has several claimants.

Prior to his death, Meucci had lost his only concluded Federal lawsuit trial related to the telephone's invention.

The Telephone Cases

The Telephone Cases, U.S. patent dispute and infringement court cases
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.

Brantford

The first long distance telephone call was made on August 10, 1876, by Bell from the family homestead in Brantford, Ontario, to his assistant located in Paris, Ontario, some 10 miles (16 km) apart.
The Bell Memorial, also known as the Bell Monument, was commissioned to commemorate Bell's invention of the telephone in Brantford; it is also one of the National Historic Sites of Canada.

Water microphone

The water transmitter described in Gray's caveat was strikingly similar to the experimental telephone transmitter tested by Bell on March 10, 1876, a fact which raised questions about whether Bell (who knew of Gray) was inspired by Gray's design or vice versa.
