Credit for the invention of the electric telephone is frequently disputed. As with other influential inventions such as radio, television, the light bulb, and the computer, several inventors pioneered experimental work on voice transmission over a wire and improved on each other's ideas. New controversies over the issue still arise from time to time. Charles Bourseul, Antonio Meucci, Johann Philipp Reis, Alexander Graham Bell, and Elisha Gray, amongst others, have all been credited with the invention of the telephone
ANTONIO MEUCCI Around 1857, Antonio Meucci created a telephone that was able to connect his bedroom with his office because of his wife´s rheumatism.
Radio technology began as "wireless telegraphy". Radio can refer to either the electronic appliance that we listen with or the content listened to. However, it all started with the discovery of "radio waves" - electromagnetic waves that have the capacity to transmit music, speech, pictures and other data invisibly through the air.
GUILLERMO MARCONI Guillermo Marconi create the radio in 1895 with the intention that humans could communicate with others over long distances without cables or thread.
In 1822, Charles Babbage conceptualized and began developing the Difference Engine, considered to be the first automatic computing machine. The Z1 was created by German Konrad Zuse. It is considered to be the first electro-mechanical binary programmable computer, and the first really functional modern computer. The Colossus was the first electric programmable computer, developed by Tommy Flowers, and first demonstrated in December1943. Short for Atanasoff-Berry Computer, the ABC began development by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937.
JHON VINCENT ATANASSOFF Atanassoff invented the first digital computer because he thought that the old machines didn’t give precise results and they were too slow. This machine had a binary system, a capacitor for storing data and a logic system for performing calculations.
The world’s first mobile phone call was made on April 3, 1973, when Martin Cooper, a senior engineer at Motorola, called a rival telecommunications company and informed them he was speaking via a mobile phone. Martin is considered the "father of the cell phone".
MARTIN COOPER "People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are”.
Is a network of satellites that orbit the earth at fixed points above the planet and beam down signals to anyone on earth with a GPS. These signals carry a time code and geographical data point that allows the user to pinpoint their exact position, speed and time anywhere on the planet.
Roger L. Easton, Ivan A. Getting and Bradford Parkinson are credited with inventing the GPS. It was invented because the US military wanted a system that could tell them exactly where they were and what the time was anywhere in the world. It also monitored the whole world for nuclear explosions, it was designed during the cold war after all and that was fairly easy to add.
The invention of the television was the work of many individuals in the late 19th century and early 20th century. But the most important inventors were Alexander Bain who introduced the facsimile machine between 1843 to 1846, and Paul Julius Gottlieb Nipkow who proposed and patented the Nipkow disk in 1884
PAUL GOTTLIEB NIPKOW Paul Nipkow devised the notion of dissecting the image and transmitting it sequentially. To do this he designed the first television scanning device. Download 17.61 Kb. Share with your friends:
