However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that.
Thomas A Augustus Watson (January 18, 1854 – December 13, 1934) was an assistant to Alexander Graham Bell, notably in the invention of the telephone in 1876.

Gardiner Greene Hubbard

A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention.
The Bell Telephone Company, a common law joint stock company, was organized in Boston, Massachusetts on July 9, 1877, by Alexander Graham Bell's father-in-law Gardiner Greene Hubbard, who also helped organize a sister company — the New England Telephone and Telegraph Company.

Elisha Gray

Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines.
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 [[Elisha Gray and Alexander Bell telephone controversy#Use of liquid transmitters for telephone experiments.2C 1873-1876|liquid transmitters in his telephone experiments for more than two years previously]].

Telephone call

The Scottish scientist Alexander Graham Bell, one of the inventors of the telephone, was greatly interested in the human voice: when he came across the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its then unwritten vocabulary into Visible Speech symbols for the first time.

Bell Boatyard

Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family.
The Bell Boatyard was a boatbuilding facility which operated as part of Alexander Graham Bell's laboratories in Baddeck, Nova Scotia from 1885 to 1928.

Anthony Pollok

Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.
Anthony Pollok (1829 – July 4, 1898) was an American patent attorney who, with Marcellus Bailey, helped prepare Alexander Graham Bell's patents for the telephone and related inventions.

Photophone
