"By the late 19th century, numerous innovators such as Antonio Meucci, Johann Philipp Reis, and Charles Bourseul had conceptualized two-way voice communication. Alexander Graham Bell, however, obtained the first patent on March 7, 1876, for an "apparatus for transmitting vocal or other sounds telegraphically," thereby securing the legal rights to the telephone's development."
"Several days after receiving the patent, Bell and his assistant, Thomas A. Watson, made their first successfully transmitted message using a crude liquid transmitter, in which Watson heard Bell exclaim, "Mr. Watson, come here, I want to see you!" On October 9, 1876, Bell and Watson talked to each other over a two-mile wire stretched between Cambridge and Boston."
"Ironically, Elisha Gray filed a patent for a telephone several hours after Bell. As the patents shared similarities, the conflict was brought to court, and Bell won the case."
A telephone retrospective exhibition runs every Tuesday through May 26th at San Francisco International Airport Terminal 2, accessible without a flight ticket. The exhibition traces telephone development from late 19th-century innovators including Antonio Meucci, Johann Philipp Reis, and Charles Bourseul who conceptualized two-way voice communication. Alexander Graham Bell secured the first telephone patent on March 7, 1876, for transmitting vocal sounds telegraphically, winning a patent dispute against Elisha Gray filed hours later. Bell and assistant Thomas Watson successfully transmitted the first message using a liquid transmitter, with Watson hearing Bell's famous request. On October 9, 1876, they communicated over a two-mile wire between Cambridge and Boston. Bell formed the Bell Telephone Company in 1877 with partners. The exhibition is made possible through a loan from the JKL Museum of Telephony.
