Alexander Graham Bell was a Scottish-born scientist, inventor, engineer and innovator who is credited with patenting the first practical telephone this date in 1876.
Bell’s father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell’s life’s work. His research on hearing and speech further led him to experiment with hearing devices that eventually culminated in Bell being awarded the first U. S. patent for the telephone on this date in 1876. Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Later, on March 10th that same year, Bell first successfully transmitted speech, saying “Mr. Watson, come here! I want to see you!” using a liquid transmitter.
An inventor named Elisha Gray had filed “an intent” to get a patent for a very similar invention earlier that same day with the U. S. Patent Office. Bell made his application several hours later and, since it was an actual application rather than just an intent to file an application, Bell was awarded the patent. The U.S. Patent Office’s decision to award the patent to Bell remains a point of contention among historians and members of the Gray family to this day. (from Wikipedia)
