Bell did like to say in fun, "Why did I ever invent the Telephone," but no one had a higher appreciation of its indispensableness or used it more freely when need was—either personally or by deputy —and he was really tremendously proud of it and all it was accomplishing.

It received its historical designation from the Government of Canada on June 1, Mabel's exact age when she became deaf would later play a part in the debate on the effectiveness of manual versus oral education for deaf children , as children who are older at the onset of deafness retain greater vocalization skills and are thus more successful in oral education programs.

Some of the debate centred on whether Mabel had to relearn oral speech from scratch, or whether she never lost it. It was invented in Brantford at Tutela Heights in the summer of Others transmitted a sound or a click or a buzz but our boys [Bell and Watson] were the first to transmit speech one could understand.

Bell was so ecstatic that he wanted to jointly name his new invention and his new daughter Photophone Greek: " light—sound " , [] [] Bell wrote: "Only think!

Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. Bell quickly disassembled it and effected a repair, to the owner's amazement.

When asked how he was able to do so Bell only needed to introduce himself. Bell also chose maroon-colored silk as it would show up clearly against the light-colored sky in his photographic studies.

Bell later shifted his attention to aerial technology. He founded the Aerial Experiment Association in 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.

The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate.

The vibrations were then converted into an electric current which traveled along the wire to the receiver. At age 11 he entered the Royal High School at Edinburgh , but he did not enjoy the compulsory curriculum, and he left school at age 15 without graduating.

In the family moved to London. Alexander passed the entrance examinations for University College London in June and matriculated there in the autumn.

Mabel had become deaf at age five as a result of a near-fatal bout of scarlet fever. Bell began working with her in , when she was 15 years old.

Despite a year age difference, they fell in love and were married on July 11, They had four children, Elsie — , Marian — , and two sons who died in infancy.

In Joseph Stearns had invented the duplex, a system that transmitted two messages simultaneously over a single wire. Inventors then sought methods that could send more than four; some, including Bell and his great rival Elisha Gray , developed designs capable of subdividing a telegraph line into 10 or more channels.

These so-called harmonic telegraphs used reeds or tuning forks that responded to specific acoustic frequencies. I want you. In this vein, Bell was an advocate of forced sterilization and was closely connected with the eugenics movement in the United States.

In , he presented data to the National Academy of Sciences indicating that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that deaf people should not be allowed to marry each other.

He also conducted sheep-breeding experiments at his estate to see if he could increase the numbers of twin and triplet births.

In , he hastily constructed a metal detector as a way to try and locate a bullet lodged in President James Garfield after an assassination attempt.

He would later improve this and produce a device called a telephone probe, which would make a telephone receiver click when it touched metal.

And when Bell's newborn son, Edward, died from respiratory problems, he responded by designing a metal vacuum jacket that would facilitate breathing.

The apparatus was a forerunner of the iron lung used in the s to aid polio victims. Other ideas he dabbled in included inventing the audiometer to detect minor hearing problems and conducting experiments with energy recycling and alternative fuels.

Bell also worked on methods of removing salt from seawater. These interests may be considered minor activities compared to the time and effort he put into making advances in manned flight technology.

By the s, Bell had begun experimenting with propellers and kites, which led him to apply the concept of the tetrahedron a solid figure with four triangular faces to kite design as well as to create a new form of architecture.
