        Alexander Graham Bell
   Our next ‘Great Inventor’ is Alexander 
   Graham Bell!
   Questions to think about:
   Have you heard of Alexander Graham Bell?
   Do you know what Alexander Graham Bell 
   invented?
   Alexander Graham Bell is famous for inventing the 
   telephone. He was very interested in speech and 
   how sounds were made.
   Alexander wanted to invent a device that would 
   transmit sound through electrical wires.
   Task 1: Read the information about Alexander 
   Graham Bell (you may make notes if you wish).
   Alexander Graham Bell was born in March, 1847 in 
   Edinburgh, Scotland. He had two brothers, Melville 
   James Bell and Edward Charles Bell. Bell’s father, 
   Alexander Melville Bell, was a phonetician, which is a 
   scientist who studies speech sounds and how they are 
   made and transmitted (sent). His mother was Eliza 
   Grace Bell, and she was an accomplished pianist.
  Bell was home-schooled by his mother, who tried to give him a 
  sense of curiosity about the world around him. To his close friends 
  and family, Alexander Bell was known by the nickname Aleck.
  In the early 1870s, Bell was living and teaching in Boston, 
  America. He spent years trying to develop a device to transmit 
  (send) the human
  voice over electrical wires.
  In 1874, he began working with Thomas Watson, a
  skilled electrician. Together, they continued
  experimenting and developing a way to transmit speech.
            th
      On 10  March 1876, Alexander and Thomas were working 
      in separate rooms. Bell made the first ever telephone call, 
      saying:
              “Mr. Watson, come here. I want to see you!”
      Following this success, Bell began to demonstrate his
      telephone in a series of public shows.
      The Bell Telephone Company was set up in 1877, and
      by 1886 over 150,000 people in the USA owned 
      telephones.
