Alexander Graham Bell is famous for his invention of the telephone. In addition to an inventor, Bell was also a respected scientist who made valuable contributions to the field of aeronautics.
On Jan. 15, 1915, Bell made his first transcontinental call from New York to San Francisco. At the age of 12 while growing up on a farm, Bell made his first invention, a dehusking machine, with pedals and nailbrushes. Alexander dropped out of school in order to began his original experiments with voice and sounds. He found that if vowels could be produced electronically, so could consonants and articulate speech.
