About the author: The Elisha Gray and Alexander Graham Bell controversy concerns the question of whether Gray and Bell invented the telephone independently. This issue is narrower than the question of who deserves credit for inventing the telephone, for which there are several claimants.At issue are roles of each inventor's lawyers, the filing of patent documents, and allegations of theft.Alexander Graham Bell was a professor of elocution at Boston University and tutor of deaf children while pursuing his own research into a method of telegraphy that could transmit multiple messages over a single wire simultaneously, a so-called "harmonic telegraph".
