Alexander Graham Bell

Alexander Graham Bell


Alexander Graham Bell was born in Scotland. His mother, who was deaf, was a musician and a painter of portraits. His father, who taught deaf people how to speak, invented "Visible Speech". This was a code which showed how the tongue, lips, and throat were positioned to make speech sounds. Graham, or "Aleck", as his family called him, was interested in working with the deaf throughout his life.

He only attended school for five years; from the time he was ten until he was fourteen, but he never stopped learning. He read the books in his grandfather's library and studied tutorials
* .

When he was a teenager, he and his brother Melly used the voice bo

x of a dead sheep to make a speaking machine that cried, "Mama!" This created even more interest in human speech and how it worked.

When he was in his early 20's, his two brothers died of tuberculosis
* . Bell himself had the disease and his father moved the family to Canada looking for a better climate in which to live. Bell recovered from the disease.

Two years later he went to Boston to open a school for teachers of the deaf and then became a professor at Boston University. It was at this time that

he met Mabel Hubbard, one of his students who was 10 years younger than he. Mabel had become deaf at the age of four due to scarlet fever. Five years later they were married. At the wedding ceremony he gave her a gift of all but 10 shares of the stock in the newly formed company called Bell Telephone Company. They had two daughters and two sons. Their sons both died at a young age.

Thomas Watson became an associate of Bell. He made parts and built models of Bell's inventions. One day while they were working Bell accidently heard the sound of a plucked reed * coming over the telegraph wire. Watson had been tuning the metal reeds in the next room. Bell drew up a plan for the telephone and they continued to experiment. The next day he transmitted the famous words, "Mr. Watson, come here. I want you!" A few months later on Feb. 14, 1876,

he applied for a patent on his telephone.

He knew he would have to work quickly to get the patent * b

ecause other people were also trying to make an invention to trans

mit the human voice. Elisha Gray Antonio Meucci also succeeded with the invention before Bell.

claims he too invented the telephone, but Bell got to the patent office an hour or so before he did. It is said that

Because Bell had the patent, he had the right to be the only one to produce telephones in the U.S. for the next 19 years.

He showed the invention to Queen Victoria of England and she wanted lines to connect her castles.

By 1917, nearly all of the United State had telephone service.

He continued to invent other things. He developed a method of making phonograph
* records on a wax disc. He made an iron breathing lung, and a device for locating icebergs at sea. He experimented with sheep. He was interested in kites that could lift a man, and he invented a hydrofoil * which set a world speed

record of over 70 miles per hour.

He along with others started the National Geographic Society and he served as its president for several years.

He became a U.S. citizen, but he died in Canada at the age of 75.
