Inventor: Alexander Graham Bell
Alexander Graham Bell was born in 1847 in Edinburg, Scotland. He was a scientist, engineer and inventor. He had two brothers named Melville James Bell and Edward Charles Bell. His father was Alexander Melville Bell and was a professor. His mother was Eliza Grace. Bell’s mother and wife were both deaf, this had a major influence on his work.
Bell was known as Aleck as a child and was interested in inventing things at a young age. His first invention was a machine that dehusked wheat faster at a flour mill that his best friends family owned.
He played the piano and was also good at entertaining people. HIs mother was deaf and Bell learned different ways to communicate with her. He used sign language and started studying acoustics.
Alexander went to Royal High School in Edinburg but didn't do very well and left at age 15. He later went to University of Edinburg and University of London.
In 1871, Bell started working on a harmonic telegraph. This invention sent messages through a single wire if each message was transmitted at a different pitch.
In 1874, Bell experimented with a phonautograph. This was a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations.
In 1875, Bell visited scientist Joseph Henry and asked his advice about the phonautograph. Bell hoped it would transmit the human voice. He hired Thomas Watson as an assistant and they experimented with acoustic telegraphy. Bell then invented the acoustic telegraph.
In 1876, Bell was able to get his telephone to work and it was patented by the US Patent office!
