    Legal dispute over the invention of the telephone

    The Elisha Gray and Alexander Graham Bell controversy concerns the question of whether Elisha Gray and Alexander Graham 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.

    Elisha Gray invented numerous improvements in the telegraph and telephone industries, including the telautograph, a forerunner of the modern day fax machine.

    Born in Barnesville, Ohio, Gray had developed an interest in telegraphic communication from an early age and built a working prototype at age ten, less than a year after the first telegraph line was erected. After attending Oberlin College for two years, Gray established himself as an electrician while simultaneously designing and inventing various telegraphic devices, including a telegraphic relay in 1867 that won him patronage from Western Union. Gray subsequently became a founder of the Western Electric Manufacturing Company, which manufactured telegraphic instruments. In 1875, Gray sold his share of Western Electric to become a full-time inventor.

    Pursuing his goals of advancing telegraph and telephone technology, Gray became engaged in a race with Alexander Graham Bell to invent a telephonic transmitting d
