Alexander Graham Bell, born in March 3, 1847 in Edinburgh, is best known for his invention of the telephone. He was an avid creator and inventor and accumilated 18 patents in his name alone as well as 14 that he shared with his collaborators by the time of his death in August 2, 1922. He inspired and worked closely with Thomas Watson, a young repair mechanic, in order to devise a method to transmit sound by electricity. ¹

In the following simulations, we will walk you through the invention and design process of one of the first stages of the telephone. As you begin each simulation a window should appear (as long as you are using a java enabled browser) which will attempt to convey a particular concept. We recommend that you procede through the simulations in sequential order, although, you should feel free to return to a previous simulation,using the links at the bottom of each page, if you feel you need to refresh yourself on a particular concept. Good luck...
