Alexander Graham Bell

Alexander Graham Bell might easily have been content with the success of his telephone invention. His many laboratory notebooks demonstrate, however, that he was driven by a genuine and rare intellectual curiosity that kept him regularly searching, striving, and wanting always to learn and to create. He would continue to test out new ideas through a long and productive life.

Oh yes now I remember. He is the inventor of telephone. Thank you so much for reminding me that thing. And thank you so much for sharing us that information.
