Inventor Biography 

ALEXANDRE GRAHAM BELL

As an inventor, Alexander Graham Bell created many things throughout his life, all of which were overshadowed by his most famous invention, the telephone. Now, Bell’s telephone bore little resemblance to the phones that we have today, but it still laid the foundations for them.

Bell’s invention of the telephone began when he became very interested in the science of sound. This interest arose because both his mother and wife were deaf. He performed a number of experiments involving sound, the most successful of which allowed him to send voice signals down a telegraph wire. This was the first major step in the invention of the telephone. After this, Bell was able to secure funding for his invention, and he hired his famous assistant Thomas Watson. Together, they invented the telephone. The first words to ever be spoken over the telephone occurred on the 10th of March 1876 by Alexander Graham Bell himself. These words were, ‘Mr. Watson, come here, I want to see you.’

Bell was not the only person at the time who was working on the invention of the telephone. This meant that, as soon as his invention was up and running, he had to race to the patent office in order to get his patent first. Once he got his patent, Bell, and his investors formed the Bell Telephone Company in 1877.
