Alexander Graham Bell and the Telephone
The invention of the telephone shaped the 20th century in many ways. Communication, internet, advertising, and warfare technology were all influenced by the invention of this simple device. Alexander Graham Bell's invention was the result of his lifelong interest in sound. Bell, born in Edinburgh, struggled to communicate with his mother, who was deaf. This childhood event drew Alexander Graham Bell to the science of sound. It would prove to be the to his greatest success.
The world of communication changed with the invention of the telephone. The device made it possible to talk to people hundreds of miles away. Every invention in the field of communications since then is a result of Bell's inventions. It changed the speed at which business communications took place. From social news to reports of war, information spread faster and more easily across the world post the invention of this device.
The telephone was not Bell's first invention. At an early age, he showed an interest in science. One of his earliest attempts at inventing was a talking machine. In 1872, Bell founded a school for the deaf in Canada. His work with deaf students led him to create "Visible Speech." This form of speech consisted of a group of phonetic symbols that could be used by the deaf to communicate with ease. During his work, he also met with Helen Keller and helped her find a teacher. Bell was a good educator and innovator.
Alexander Bell filed his patent for the telephone hours before another inventor, Elisha Gray. Bell had been aware of growing developments in the field and wanted to gain the advantage over his competitors. The delay in patenting lost Gray the chance to make history. Alexander Graham Bell went on to found the Bell Telephone Company.
The invention of the telephone did not reach the masses immediately. Upon its introduction, it was viewed as an expensive device. It took a long time and a number of other technical developments before the telephone became a part of American homes. But even in its early years, the benefits of the telephone were obvious.
The telephone was not Bell's only invention. He continued to develop devices for various purposes. He was among the first to create a device that would help patients breathe more easily. It is considered by many historians to be the earliest form of the "Iron Lung." He also contributed to creating a more practical phonograph for Thomas Edison. He was also the founder of the journal "Science," which grew to become the National Geographic Society. It was these contributions that made Bell a respected innovator in the world of science.
Alexander Graham Bell remains one of the most famous inventors of the 20th century. His contributions to science changed the world in many ways. The telephone remains the most vital invention of the century. Its arrival changed the way human society functioned. From the field of communications, education, warfare, computers and space, the role of the telephone cannot be ignored. It has become the lifeline of modern communication.
