The Second in the World to Invent Telephone

Elisha Gray

"Elisha Gray may not have received a patent for inventing the telephone, but he still made huge advances in the technology people use to communicate. Despite never completing a formal education, failing as a dairy farmer, and possibly having the plans for his best invention stolen by his rival, Alexander Graham Bell, Elisha still went on receive 70 patents for a variety of things including a very early version of what we now know as a fax machine and the world's first electric musical instrument!"--
