Hi, 10th March as I write and just could not let this day go by without remembering Alexander Graham Bell ... "Mr. Watson,come here,I want you." .. he is reputed to have said. The first discernible speech transmitted over a telephone when Bell summoned his assistant, who was in another room at the time. Some stamps and some of the history. I like the Canadian stamp the best.
Interesting story... some here for your enjoyment... sourced from
here Alexander Graham Bell, born in Edinburgh, Scotland, in 1847, was the son of Alexander Melville Bell, a leading authority in public speaking and speech correction. The young Bell was trained to take over the family business, and while still a teenager he became a voice teacher and began to experiment in sound. In 1870, his family moved to Ontario, Canada, and in 1871 Bell went to Boston to demonstrate his father's method of teaching speech to the deaf. The next year, he opened his own school in Boston for training teachers of the deaf and in 1873 became professor of vocal physiology at Boston University.
In his free time, Bell experimented with sound waves and became convinced that it would be possible to transmit speech over a telegraph-like system. He enlisted the aid of a gifted mechanic, Thomas Watson, and together the two spent countless nights trying to convert Bell's ideas into practical form. In 1875, while working on his multiple harmonic telegraph, Bell developed the basic ideas for the telephone. He designed a device to transmit speech vibrations electrically between two receivers and in June 1875 tested his invention. No intelligible words were transmitted, but sounds resembling human speech were heard at the receiving end.
On February 14, 1876, he filed a U.S. patent application for his telephone. Just a few hours later, another American inventor, Elisha Gray, filed a caveat with the U.S. Patent Office about his intent to seek a similar patent on a telephone transmitter and receiver. Bell filed first, so on March 7 he was awarded U.S. patent 174,465, which granted him ownership over both his telephone instruments and the concept of a telephone system.
Three days later, on March 10, Bell successfully tested his telephone for the first time in his Boston home. In May, he publicly demonstrated the invention before the American Academy of Arts and Sciences in Boston, and in June at the Centennial Exposition in Philadelphia. In October, he successfully tested his telephone over a two-mile distance between Boston and Cambridgeport.
In 1877, he formed the Bell Telephone Company with two investors, and the first commercial applications of the telephone took place.
have a great day .. Michael
