We give credit to Boston Speech Teacher Alexander Graham Bell for inventing the telephone in 1876, taking out a patent for a device that would transmit his human voice over wire.However his rival, John Philip Reis, a Frankfurt Physicist had invented in 1861, fifteen years earlier, an apparatus for carrying sound impulses across a wire.It was constructed of a beer barrel cork (for the mouthpiece), a sausage skin (as the diaphragm) and it did transmit successfully the human voice however it was incomprehensible.Bell did know of Reis's work, credited him but that was as far as it went.In 1900, 25 years after Reis's death, the United States Government was still harassing Bell saying that he knew of the sausage skin speaker and concealed this from the patent office.If by "Telephone" you mean an instrument that can carry a voice across a wire, the Reis is the inventor of the telephone, not Alexander Bell.This is derived from a book "Fabulous Fallacies" by Tad Tuleja, an excellent source where you will find that most of what we were taught is wrong.I hope this helps your report. Good Luck
