The Telephone
Anna Blackburn
World History period 7
4.27.10 Thesis: The telephone affected the industrial revolution by helping
make communicating with others much easier, lowering the amount of time
needed to send a message, and receiving messages far more efficiant than ever before. The teleohone was discovered one day while experimenting with the
"harmonic telegraph", when Alexander Bell discovered you could hear
sound over a wire.
Before the telephone was invented, people would send messages that were written by hand and they would have to deliver them themselves, or they would have other people deliver them for them Although the system of writing messages by hand and delivering was somewhat efficient, the telephone was more influencial. It got the messages to people faster, which was something people had never experienced before. When Bell had started working on discovering the telephone, the telegraph had already been around and in use for some 30 years. There has been debates around the world about the true inventor of
the telephone because another scientist named Elisha Gray had been working on the same project around the same time, but there is historical evidence leading us to believe it was truly Bell "Concentrate all of your thoughts upon the thought at hand. The suns rays do not burn until brought to a focus." In Conclusion, the telephone affected the industrial revolution in a major way by helping make communicating easier, lowering the amount of time needed to send a message, and also making it easier to receive a message better than ever. Mark Twain was one of the first people to have a private telephone in his home & the first telephone company was "The Bell Telephone Company" http://sociallady.files.wordpress.com/2009/11/alexander_graham_bell_500px.jpg http://www.itu.int/ITU-D/ict/statistics/ict/graphs/fixed.jpg http://billdunlap.files.wordpress.com/2009/04/telephone.jpg The earliest telephones were all
