What is Alexander Graham Bell famous for?

Alexander Graham Bell was a very creative and ingenious man. He was a teacher for the deaf and creator and inventor extraordinaire. You may know Bell from one of his most famous inventions. The telephone. Bell invented the telephone when he was twenty-nine years old. How did we find Bell's telephone you may ask? Well in the year of 1876, the one-hundredth anniversary of the Declaration of Independence, there were many celebrations going on. Including one of the biggest world's fairs in Philadelphia. Bell knew that this world fair was going on, but he was to busy grading students' papers. Bell was hesitant present his telephone. Perhaps it didn't work properly. Maybe he thought it needed more work. Bell's fiancee  Mabel Hubbard thought differently. Mabel and her father were very eager for Bell to show off his telephone. Bell still refused to go. Bell was very relieved when he found out that he missed the deadline to apply for a space in the electrical inventions pavilion at the world's fair. On June 24, it was a typical day for Bell. He was working hard at the university. Mabel surprised Bell that afternoon by arranging an carriage ride for the two of them. What Bell didn't know was that this carriage was taking them to the train station to go to Philadelphia. Mabel had hidden a packed suitcase for Bell in the carriage.When they got to the train station Bell refused to board the train. Although Mabel was deaf, she could read people's lips and could pronounce some words. Mabel said, "If you don't love me enough to do this for me, I won't ,marry you!" Bell then boarded the train. Bell's telephone would be judged on June 25. It was brutally hot and the Philadelphians were suffering. Bell hated the heat. It gave him piercing headaches. Then suddenly Bell recognized someone. The man was Dom Pedro. Bell and Pedro spent time discussing methods of teaching the deaf or hearing-impaired. Dom Pedro was also one of the judges at the world fair. Pedro asked to see Bell's invention. So Bell led Pedro over to the transmitter five hundred feet away and began reciting a speech from Hamlet. Pedro's eyes lit up. "I hear!  hear!, he called out.All of the other judges were amazed and rushed over to hear the talking machine. Everyone ignored the heat and humidity to examine this wonderful machine. When Bell returned to Boston he had been give a Centennial Exhibition award for his telephone.
