Information on alexander graham bell and his invention of telephone?
Question:
Answer:
Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist and inventor. Today, Bell is still widely considered to be the foremost inventor of the telephone, although this matter has become controversial, with a number of people claiming that Antonio Meucci was the "real" inventor (in June 2002, the United States House of Representatives passed a symbolic bill officially recognizing Meucci for his contributions to the invention of the telephone).

He demonstrated his device to telegraph engineers, gave lectures to scientists and helds telephone conversations with divers submerged in tanks of water. He demonstrated his invention to Queen Victoria, who was much impressed. She ordered a private line to be laid between Osborne House, on the Isle of Wight, and Buckingham Palace.
