The First Telephone

The first telephone was invented by Alexander Graham Bell which started off as a harmonic telegraph. This is a device that allows multiple messages to be transmitted at the same time over a wire. This led Bell to become preoccupied with trying to find a way to transmit human voices over wires. However, in 1875 with the help of Thomas Watson, they came up with a simple receiver that was able to turn electricity into sound. Many other scientists were working on very similar technologies which causes some debate as to who should really be credited with the invention of the telephone. Scientists like Antonio Meucci and Elisha Gray are some examples that could have created the telephone first and not Alexander Graham Bell. The first-ever telephone call was Bell saying to Watson, “Mr. Watson, come here. I want you”. This happened in 1876 and by 1877 the Bell Telephone Company was created, later known as AT&T. About thirty years later in 1915, the first transcontinental phone call was made from New York to San Francisco.

            Today the telephone brings us instantaneous communication, as opposed to writing and delivering messages by hand. This method of communication allowed for governments to steer the course of battle and war. It eliminated the delay of previous communication to positively affect the government, journalism, business and exc. One major impact is the use of emergency response time. By being able to call 911 the telephone greatly reduced the response time of emergency responders as well as the increase in the number of reported emergencies. The telephone also led to economic growth and increased profits. Quick communication improved the ways business could deliver its goods to fill customer orders. This also gave farmers a way to see the most current price for their crops. Mobile communication allows anyone to work from any location at any time. This decreases the worker’s time to commute by allowing them to work from home or help the company save money by not renting office space.

            To me, the invention of the telephone is one of the most commonly used inventions today. Every day we send messages to others just from our phones. Although this started with just talking on the phone, it eventually improved to be able to send messages as well. The telephone is something that we don’t really appreciate everyday but simply take it for granted that we can communicate through a device to someone that is across the world in another country.

The First Email

Email, also known as electronic mail, is a way for people to message each other using electronic devices. The first email was created by Ray Tomlinson and sent in 1972. He was working on this as a personal side project. Tomlinson also initiated the use of the "@" symbol to separate the names of the user and the user's machine in 1971. The first email he sent was a message from one Digital Equipment Corporation DEC-10 computer to another DEC-10 computer. Nowadays email operates across computer networks, but mostly the internet. At one point, email systems required both the author and the recipient to be online at the same time, common with instant messaging. Today, neither the user or the computer needs to be online to receive mail since servers accept, forward, deliver, and store messages. This allows for users to be “offline” but still receive messages from others that were sent at any time.

         I think the invention of the email is something very important since it is similar to texting but is still used today. It’s interesting that one person came up with the “@” symbol just to have a separation between someone’s name and a company. I find it surprising that email is still commonly used today since there are many similar forms of communication. Especially, texting seems quicker but in reality, it might be easier to read a long message over email than through text message. Overall, email has come a long way with several companies offering free emails and allowing anyone to make as many emails as they want.
