Telephone - Answering Machines And Services

History 1888 � Common battery system developed by Hammond V. Hayes, allows one central battery to power all telephones on an exchange, rather than relying on each units own battery.

In this article we're going to discuss one of the most important inventions to compliment the telephone since its creation, the answering machine.

The telephone was invented for the purpose of one person being able to call another person and speak to them. For the person making the call, well, they're the one making it so their role is already completed. But what about the person at the receiving end? They do have to pick the phone up in order for the call to be completed and therein lies the problem with this system. It isn't exactly fool proof. The person on the other end could be in the shower or out of the house altogether and end up missing the call, leaving the person on the calling end frustrated. Can't even leave a message to call them back.

History 1911 � American Telephone and Telegraph (AT & T) acquire the Western Union Telegraph Company in a hostile takeover. They purchased stocks in the company covertly and the two eventually merged.

The answering machine to the rescue.

Even though the answering machine is a fairly new invention it actually goes back to something that was created way back in 1898. In that year, a Danish telephone engineer by the name of Valdemar Poulsen patented what he called a telegraphone. This was the first practical machine for magnetic sound recording and reproduction. It was actually able to record telephone conversations. On a wire, it recorded the varying magnetic fields produced by a sound. The magnetized wire was then used to play back the sound.

History 1946 � Worlds first commercial mobile phone service put into operation. It could link moving vehicles to a telephone network via radio waves.

However it wasn't until 1935 that we got the first automatic answering machine which was invented by Mr. Willy Muller. The first answering machine was laughably huge at three feet tall. It was very popular with Jewish people who were not allowed to answer the phone on the Sabbath.

History 1955 � Saw the beginning of the laying of transatlantic telephone cables.

But the first answering machine sold in the United States was the Ansafone, which was created by inventor Dr. Kazuo Hashimoto for Phonetel. It figures that it would be the Japanese would be the first to come up with our first commercially used answering machine.

The contributions by Phonetel weren't the end of our progress with answering machines, however. Casio actually created what is known as the first commercially viable answering machine in 1971. They created what was called the Telephone Answering Device (TAD) which was the model 400, now seen in the Smithsonian Institute.

History 1876 � Alexander Graham Bell invents the telephone, beating Elisha Gray by a matter of hours.

Also in 1971 Phonemate gave us its first answering machine which was also the model 400. It worked a little different from Casio's machine in that it weighed 10 pounds and held up to twenty messages on reel to reel tape. It came with an earphone that allowed the user to retrieve messages privately.

The first digital TAD was given to us by the same person who gave us the first Ansafone. He invented it in 1983 and it was given Unites States patent number 4,616,110 and was called Automatic Digital Telephone Answering.

History 1877 � The very first permanent outdoor telephone wire was completed. It stretched a distance of just three miles.

Other enhancements and additions were made to answering machines which now include what is known as voice mail, which was actually created before the digital TAD patent (patent number 4,371,752) but didn't become popular until afterwards. Voicemail was actually invented in 1979 by Gordon Matthews. He sold the first system to 3M company.

History 1874 � Principal of the telephone was uncovered.
