Alexander Graham Bell exhibited the first two-way telephone conversation over external wires on this day in
9 October 1876.
Three hours were spent on the first two-way long distance phone call. Thomas G. Watson spoke with Alexander Graham Bell at the Walworth Mfg. CO. headquarters on 69 Kilby Street in Boston, Massachusetts, via telegraph wire from Cambridgeport.
Elisha Gray creates a liquid transmitter for a telephone on February 11, 1876, but he never actually makes one.
Around 9:30 am on February 14, 1876, Gray or his attorney delivers Gray’s telephone patent caveat to the Washington, D.C. Patent Office.
Around 11:30 a.m. on February 14, 1876, Bell’s attorney submits the telephone patent application to the same patent office. Bell’s attorney wants that it be entered into the cash receipts blotter right now.
1:30 pm on February 14, 1876: Elisha Gray’s patent caveat is recorded in the cash blotter around two hours later. Gray could have turned his caveat—which was not a complete application—into a patent application and challenged Bell’s priority, but he chose not to do so on the advice of his attorney and because of his engagement in acoustic telegraphy. Bell ultimately received the patent as a consequence.
Graham Bell receives approval for U.S. Patent No. 174,465 on March 7, 1876.
Bell successfully transmitted speech for the first time on March 10th, 1876, saying, “Mr. Watson, come here! I’d want to see you. employing Bell’s own electromagnetic receiver and a liquid transmitter as per Gray’s disclaimer.
Thomas Alva Edison submitted the first acoustic telegraphy patent application on May 16 of that year, and on October 10 of that year, he was awarded U.S. patent 182,996.
On August 10, 1876, Alexander Graham Bell made the first long-distance telephone conversation, travelling six miles between the Canadian cities of Paris and Brantford.
The telephone is Alexander Graham Bell’s most famous invention. He immigrated to the United States as a deaf educator, and when visiting his hearing-impaired mother in Canada, he had the concept for “electronic speech.” This inspired him to create the microphone and, subsequently, the first telephone, which he called the “electrical voice machine.”
On March 3, 1847, Bell was born in Edinburgh, Scotland. His stay at the University of London, where he had enrolled to study anatomy and physiology, was cut short when his family emigrated to Canada in 1870. His parents thought that the only way to rescue their final kid was to leave England because they had already lost two children to disease.
On August 2, 1922, Bell passed away. All US telephone service was suspended for one minute on the day of his funeral.
