The telephone is one of the greatest inventions in history.
Early telephones were nothing like the ones we have today. Telephone is
the Greek word for “far sound.” This is how
the telephone became what it is today. The telephone was invented by Alexander
Graham Bell in 1876, with the help of Mr. Bell invented
the telephone by accident when he was trying to invent a device that could send more
than one telegram at the same time. Mr. Watson and
Mr. Bell were both practicing their musical instruments in separate rooms. Bell
spilled some polishing liquid on himself and
said over the telephone, “Mr. Watson, come here, I want you.”
Mr. Bell also invented the microphone and the speaker. The first
telephone didn’t have a bell, so the caller had to tap the phone with a hammer
to let the receiver know a call was being sent to them. It was Thomas Watson who
invented the bell. The first
telephone operators only answered the phone when they felt like it. The operator
would pick up the phone and say, “Number please.” If the number wasn't busy, the
operator took a chord and plugged it into a switchboard. This connected the caller to the number.
The operator
system changed because there were too many people with telephones, and it cost
too much money to have that many operators working. The Bell
Telephone Company was founded by Alexander Graham Bell in 1877 to build a
nationwide telephone system. By 1881, there were 132,700 Bell telephones in
homes. By 1930, 15,193,000 phones
were in service. The
telephone became one of the most popular methods of communication. People wrote
fewer letters and visited less often. A
farmer in Gratiot, Wisconsin in the 1900’s took apart his telephone to see how
it worked. When the carbon in the phone spilled out, he realized he could
replace it with gunpowder. But the instant he tried to call somebody, the
telephone blew up! The farmer wasn’t harmed, but he learned one lesson:
telephones don’t make good guns. Mr. Watson
and Mr. Bell were the first people, on January 15, 1915, to make a In the
1940’s, after World War II, telephones became very popular. But it was too
expensive for each home to have it’s own line, so the party line system was
created. Although each home would have its own telephone, the party line system
had between two and four homes sharing a single phone line. This meant that you
could pick up your telephone and listen to your neighbor’s conversations.
A phone call works by going through the telephone wire and then to a radio wave. The radio wave sends it to the nearest transmitter, which sends it to the nearest telephone wire of the person receiving the call. To transmit calls, they used to use copper wires. Today, fiber optic cables and laser lights are used. What would be the first thing you'd hear if you were on a telephone that was using the
operating system (operator)? What was
the first message sent on the telephone? How many bell
telephones were in homes by 1930? With all the new technology in the world, what’s ahead for the telephone? Perhaps someday people could have telephones on their wrist, or the person they’re talking to could be on their phone as a hologram. Or probably things we can’t even imagine. It’s all thanks to Alexander Graham Bell. Citations Books Holland, Gina and Amy Stone. Telephones. New York, New York: Benchmark Books, 1996. Skurzynski, Gloria. Get the Message.
