To correct a glaring error not K.O.'s fault as he copies from another source
but that of the original author, the description of the first telephone
transmitter (microphone) is wrong. The description is that of the receiver
(earphone) which is correct, an electromagnet biased by a permanent
magnet vibrating a thin steel diaphragm.
The transmitter was an electrolytic device containing acid which Mr. Bell
spilled on himself and called his assistant in the next room with a receiver.
When he called "Mr. Watson, come here, I need you." Watson heard him through
the telephone, the experiment was a success.
The early Bell Telephone Company didn't do very well, telephones containing
spillable dangerous acid in large, clumsy microphones weren't very popular.
Western Union wanted a better mouse trap so they hired Edison who invented
the more compact, efficient and safe carbon microphone superceded by the
electret (low voltage condenser mic) in the telecommunications industry.
If you want more you'll have to read it yourself and find it interesting,
a long story of a family of Bell Telephone companies, Bell Laboratories,
AT&T Long Lines, Western Electric, big fish, little fish and shark attacks.
"New Jersey, the most American of all states. It has everything from
wilderness to the Mafia. All the great things and all the worst,
like Route 22."
