Alexander Graham Bell Essay

Tesla advanced the way people lived and interacted through many inventions. One of Tesla’s many inventions, the speaker, helped many communicate

While the telephone had the biggest impact on society, some of his later inventions went unknown. One of Bell’s next major inventions was the metal detector. The reason why Bell wanted to create such a device was so he could find a bullet that had shot President James Garfield. This device that was supposed to find a bullet grew into a masterpiece that would save many lives in the future. Although Bell’s invention didn’t save the twentieth President of the United States, it saved thousands of WW1 and WW2 soldiers. The soldiers used this astonishing creation to clear landmines and unexploded bombs across all of Europe. As impressive as the metal detector was, Bell’s most prized invention was the photophone. A photophone is a device that enabled sound to be transmitted on a beam of light. In present day, laser and fiber optic communication systems are based off of this invention. In 1881, they successfully sent a photophone message approximately 200 yards from one building to another. As Alexander G. Bell put, “...the greatest invention I have ever made. Greater than the

Alexander invented the first ever telephone. He lived from 1847 to 1922, he was a scottish born american scientist. He worked at a school for the deaf while trying to invent a machine that would send sound by electricity.”Bell was granted the first official patent for his telephone in March 1876, though he would later face years of legal challenges to his claim that he was its sole inventor, resulting in one of history’s longest patent battles.” When he got his machine to work, he offered to sell his patent to Western Union for 100 thousand dollars. Western Union turned down his offer because the telephone did not really hit it off at first. So Alexander decided to make his own telephone company. “The Bell Telephone Company, a common law joint stock company, was organized in Boston, Massachusetts on July 9, 1877, by Alexander Graham Bell 's father-in-law Gardiner Greene Hubbard, who also helped organize a sister company — the New England Telephone and Telegraph Company.” Once the telephone hit off and everyone

Alexander Graham Bell, best known as the inventor of the telephone, worked at a school for the deaf while attempting to invent a machine that would transmit sound by electricity. Bell was granted the first official patent for his telephone in March 1876. The telephone changed ways in communicated. The telephone has made communication more efficient and faster since it was first developed. Its great for emergency purpose especially if you really need to talk to someone as soon as possible. It has made a big impact on our lives today.

Bell had long been fascinated by the idea of transmitting speech, and by 1875 had come up with a simple receiver that could turn electricity into sound. Bell worked with Thomas Watson on the design and patent of the first practical telephone. Alexander Graham Bell thought he was on to something, but no one wanted his new invention. In all, Bell held 18 patents in his name alone and 12 that he shared with collaborators. United States Patent No. 174,465 was issued to Alexander Graham Bell in 1876, and became recognized as the most valuable patent in history. He died on August 2, 1922, in Cape Breton Island, Nova Scotia, Canada.

Let me now explain the childhood of Alexander bell the inventor of the telephone. Alexander was born on March 3rd 1,847. His dad teaches a class of deaf people, But his mom Elisa Grace was always at the house taking care of Bell. Alexander’s dad inspired Bell about inventing. When he showed his invention visible speech But before he started inventing he really liked playing the piano and got a music education.Then his dad asked Bell and his two sisters if they could support his invention by using examples of how it works in 1851. Then, Bell enrolled as a student-teacher

In 1876, Alexander Graham Bell patented the telephone which was the first electrical device that could transmit speech. While the telephone was one of the best inventions in history, it was completely pointless to the deaf because they couldn 't hear. The deaf now have hearing aids and cochlear implants that help them hear, although; a hearing aid will only be effective for about one in five people with hearing loss. The first mention of hearing aids was in 1588 in Giovanni Battista Porta’s book “Natural Magick". In his book, he discussed an early hearing aid that were wooden carvings of the ears of superior hearing animals.

In 1874, the idea of creating a device to transmit speech through an electrical current formed in Bell’s mind. He spent much time experimenting and designing a device that fit the image expanding within the confines his head. Two years later he applied for a patent, which was granted on March 7, 1876.

Alexander Bell was an inventor, self-taught student, and teacher. He was an important part of communication technology history. The invention of the telephone made a huge impact on the world.

After some years of moving, when Alexander was twenty-five he established a school for the deaf in Boston, Massachusetts. The following year became a professor in speech and vocal physiology at Boston University (History.com). Even though Alexander’s

Samuel F. B. Morse perfected the telegraph in 1832. A telegraph is a device that sent information to somewhere through wires. He studied magnetism and electricity. Later he put other scientists work together in a certain machine which was the telegraph. The telegraph could do many different things. Some of the things that it could do was send pulses and surges. The telegraph had a telegraph key. The telegraph key controlled how long each pulse is. When it got to the end of the wire it turned into clicking sounds, like a dot. If you were very good at working with the telegraph you could send and receive messages a lot of words per minute. There were different sounds that the telegraph could make and each sound was a different letter of the alphabet

He loved his science classes and he learned more and more about speech. Aleck also spent hours studying sound. He studied the way a piano works; how its strings vibrated back and forth. The elder Bell encouraged Alexander and instilled an appreciation for learning and intellectual pursuits. By age 16, he had joined his father in his work with the deaf and soon had full charge of his father’s London operations. In July, 1870, the family settled in Brantford, Ontario, Canada. There, they had set up a workshop to continue his study on the human voice. In 1871, Bell moved to Boston and he began to work on a device that would allow the telegraph transmission of several messages set to different frequencies. He found financial backing through two local investors. These local investors had been Thomas Sanders and Gardiner Hubbard. At this time, a device called the telegraph was the fastest way to send messages. Between 1873 and 1874, Bell spent long days and nights trying to perfect the telegraph. Bell wanted to make the telegraph work faster and to find a way to send more than one message over a wire at a time. While he was working on that, he got an even bigger idea. What if voices could travel by wire from place to place? That would be faster than the telegraph. Bell was not good at building things. He needed someone who could turn his sketches, or drawings, into a working machine so Thomas Watson become his assistant. Watson

This was a distance of 5 miles. The other people at the end heard faint noises, but could not hear what Bell was saying. In the next test, Bell shortened the distance to 4 miles. The people concluded that they could hear a distinct and audible voice. This event proved that Bell’s telephone would work for any distance. Bell’s colleagues offered to sell the patent for $100,000. The Western Union said it was nothing more than a toy and they would not pay that much. Later, his partners said to Bell that he could sell his patent for about $25 million. Bell thought it was too late and decided not to sell it and to keep his company. Bell began to show the world his revolutionary design. One of the more famous demonstrations was from New York to Chicago in 1892. Queen Victoria showed excitement and said, “Most extraordinary!” The positive advice Bell had received made him proud of his prototype design. Elisha Gray had similar prototypes with his liquid transmitter idea. In another prototype, Bell looked at Thomas Edison’s past patents. He found one called the Carbon Microphone. This telephone worked better in long range and you didn’t have to shout at the receiving end. This improved Bell’s

Then Alexander Graham Bell developed a photo phone which is an optical voice transmission system. Free space light is used to transmit the human voice up to 200meters. Mirrors are placed on to the diaphragm towards the mouth piece of the photo phone. And the parabolic reflector is placed at the other end with a light sensitive resistor. As a person spokes into the photo phone, creates a vibration in diaphragm with the different intensities of light onto the selenium resistor. The intensity of light passed through the telephone receiver converts light back into speech. Bell believed that this discovery is better for telephone because it does not require
