On March 3, 1847, Alexander Graham Bell was born in Edinburgh, Scotland. He relieved his education at Edinburgh University and University College, London. He then moved to Ontario, Canada wit his parents in 1870. Both his father and grandfather spent their lives studying human speech and teaching the deaf to speak. Alexander followed in their footsteps. Alexander's main goal in life was to help the deaf.

In the year 1870, Bell began teaching deaf students in Boston, Massachusetts. The next year he started a school for teachers of the deaf which focused on the method of visible speech (sign language). The visible speech method was created by his father. He later became a professor at Boston University in 1873.

Between the years of 1874 to 1875, Bell started working on his greatest invention. This invention was the telephone which was inspired by experiments to help the deaf. In Boston, March 10, 1876, the first successful message was transmitted by the telephone. Bell told his assistant, Mr. Watson: 'Mr. Watson, come here; I want you.' On February 14 of that same year, Bell's lawyer filed for a patent for Bell's discovery.

At the Centennial Exposition of 1876, in Philadelphia, PA, Bell demonstrated his remarkable invention. Bell's telephone fascinated the general public. He later started his own telephone company. In the year 1880, Bell won the French Volta prize of 50, 000 francs for inventing the telephone. He used the money to open up the Volta Laboratory and the American Association to Promote the Teaching of Speech to the Deaf in Washington, D. C.

This was an information center for the oral education of the deaf. Bell also experimented with sound and aviation. He invented the audiometer which measured the intensity of sound. On August 2, 1922, Bell died at his summer estate on Cape Breton Island in nova Scotia. During Bell's funeral service, every telephone was kept silent on Bell's telephone system.
