He worked on acoustic telegraphy with his assistant, an electrical designer named Thomas Watson.

On February 14, , Bell and an American electrical engineer named Elisha Gray both filed patents with the U.S.

Patent Office covering the transmission of sounds telegraphically. There is debate about who got there first but the patent was awarded to Bell. A few days later, he succeeded in getting his telephone to work using elements similar to those f Gray&#;s water transmitter.

Bell improved on the design of his telephone and by , more than , people owned telephones in the United States.

Bell had a strong interesting in other scientific fields, conducting medical research, searching for alternative fuel sources, experimenting with metal detectors, developing hydrofoil watercraft and much more.

Both of his two brothers die from tuberculosis, which was a common cause of infant mortality in those days.

Bell didn&#;t go to school.

He was educated at home by his mother. Together, they explored anything and everything that interested them, leading to the healthy development of wide-ranging interests and an insatiable curiosity about the world and its works.

Later on, Bell did go to a private school for one year in order to ready him for two years of more formal education at  The Royal High School.

When he was 16 years old, Bell started his early research into speech mechanics.

Even at such a young age, he took up a post at the Weston House Academy, teaching both music and elocution.

Bell&#;s first invention was a homemade wheat dehusking machine that he crafted out of paddles and nail brushes for his best friend&#;s father, who owned a flour mill.

This earned Bell the title of honorary chief.

Bell began work on what we know as the telephone in an effort to save costs of constructing telegraph lines that could not support multiple lines.

In , he produced his first simple receiver, which was capable of transforming electrical impulses into audible sound.

Unlike many new inventions, the telephone was adopted quickly.

Flash cards.

After only a year, the very first telephone exchange had been constructed in Connecticut, and the Bell Telephone Company was founded. In consequence of the rapid spread of telephonic communications, Bell soon became a very wealthy man.

Bell was awarded a number of prestigious prizes and went on to further develop experiments in many fields.

He continued to develop technologies to help deaf people.

Bell was connected with the eugenics movement in the United States. In his lecture &#;Memoir upon the formation of a deaf variety of the human race&#; presented to the National Academy of Sciences on November 13, , he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf shouldn&#;t marry.
