Alexander Graham Bell.jpg

Alexander Graham Bell ( March 3,1847 – August 2, 1922 ) was an outstanding scientist, inventor, and innovator. Born and brought up in Scotland, he emigrated to Canada, and later, the United States. Over the years, his work and efforts were expressed between both countries. Bell is widely acclaimed as the prime developer of the telephone, with considerable honourable mention to Antonio Meucci and Philipp Reis. In addition to Bell's work in telecommunications, he was responsible for important advances in aviation and hydrofoil technology. {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 2 | Portal:Telecommunication/Selected biography/2 }} Portal:Telecommunication/Selected biography/2

Marconi 1909.jpg

Guglielmo Marchese Marconi, GCVO (25 April 1874-20 July 1937) was an Italian inventor, best known for his development of a practical radiotelegraph system, which served as the foundation for the establishment of numerous affiliated companies worldwide. He shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun, "in recognition of their contributions to the development of wireless telegraphy". While growing up, Marconi had an intense early interest in science, and was especially fascinated by electricity. {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 3 | Portal:Telecommunication/Selected biography/3 }} Portal:Telecommunication/Selected biography/3 Nikola Tesla (Serbian Cyrillic: Никола Тесла) (10 July 1856 – 7 January 1943[1]) was an inventor, physicist, mechanical engineer and electrical engineer. Born in Smiljan, Military Frontier, Austria-Hungary, he was an ethnic Serb subject of the Austrian Empire and later became an American citizen. Tesla is best known for his many revolutionary contributions to the discipline of electricity and magnetism in the late 19th and early 20th century. Tesla's patents and theoretical work formed the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor, with which he helped usher in the Second Industrial Revolution.

Morse was born in Charlestown, Massachusetts (now part of Boston), on April 27, 1791, and educated at Yale College (now Yale University). He studied painting in London and became a successful portrait painter and sculptor. In 1825 he helped found the National Academy of Design in New York City, and the following year he became the first president of the institution. He continued his painting and became a professor of painting and sculpture at New York University in 1832. About that time he became interested in chemical and electrical experiments and developed apparatus for an electromagnetic telegraph that he completed in 1836. The following year he filed a caveat, or legal notice, at the patent office in Washington, D.C., and tried without success to obtain European patents for his apparatus. He also invented a code, now known as the Morse code, for use with his telegraph instrument. Several contemporary scientists gave Morse significant financial and technical help with his work on the telegraph and Morse code. {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 5 | Portal:Telecommunication/Selected biography/5 }} Portal:Telecommunication/Selected biography/5 Portal:Telecommunication/Selected biography/5 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 6 | Portal:Telecommunication/Selected biography/6 }} Portal:Telecommunication/Selected biography/6 Portal:Telecommunication/Selected biography/6 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 7 | Portal:Telecommunication/Selected biography/7 }} Portal:Telecommunication/Selected biography/7 Portal:Telecommunication/Selected biography/7 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 8 | Portal:Telecommunication/Selected biography/8 }} Portal:Telecommunication/Selected biography/8 Portal:Telecommunication/Selected biography/8 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 9 | Portal:Telecommunication/Selected biography/9 }} Portal:Telecommunication/Selected biography/9 Portal:Telecommunication/Selected biography/9 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 10 | Portal:Telecommunication/Selected biography/10 }} Portal:Telecommunication/Selected biography/10 Portal:Telecommunication/Selected biography/10 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 11 | Portal:Telecommunication/Selected biography/11 }} Portal:Telecommunication/Selected biography/11 Portal:Telecommunication/Selected biography/11 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 12 | Portal:Telecommunication/Selected biography/12 }} Portal:Telecommunication/Selected biography/12 Portal:Telecommunication/Selected biography/12 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 13 | Portal:Telecommunication/Selected biography/13 }} Portal:Telecommunication/Selected biography/13 Portal:Telecommunication/Selected biography/13 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 14 | Portal:Telecommunication/Selected biography/14 }} Portal:Telecommunication/Selected biography/14 Portal:Telecommunication/Selected biography/14 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 15 | Portal:Telecommunication/Selected biography/15 }} Portal:Telecommunication/Selected biography/15 Portal:Telecommunication/Selected biography/15 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 16 | Portal:Telecommunication/Selected biography/16 }} Portal:Telecommunication/Selected biography/16 Portal:Telecommunication/Selected biography/16 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 17 | Portal:Telecommunication/Selected biography/17 }} Portal:Telecommunication/Selected biography/17 Portal:Telecommunication/Selected biography/17 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 18 | Portal:Telecommunication/Selected biography/18 }} Portal:Telecommunication/Selected biography/18 Portal:Telecommunication/Selected biography/18 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 19 | Portal:Telecommunication/Selected biography/19 }} Portal:Telecommunication/Selected biography/19 Portal:Telecommunication/Selected biography/19 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 20 | Portal:Telecommunication/Selected biography/20 }} Portal:Telecommunication/Selected biography/20 Portal:Telecommunication/Selected biography/20 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 21 | Portal:Telecommunication/Selected biography/21 }} Portal:Telecommunication/Selected biography/21 Portal:Telecommunication/Selected biography/21 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 22 | Portal:Telecommunication/Selected biography/22 }} Portal:Telecommunication/Selected biography/22 Portal:Telecommunication/Selected biography/22 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 23 | Portal:Telecommunication/Selected biography/23 }} Portal:Telecommunication/Selected biography/23 Portal:Telecommunication/Selected biography/23 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 24 | Portal:Telecommunication/Selected biography/24 }} Portal:Telecommunication/Selected biography/24 Portal:Telecommunication/Selected biography/24 {{../box-footer|}} {{../box-header|Telecommunication/Selected biography 25 | Portal:Telecommunication/Selected biography/25 }} Portal:Telecommunication/Selected biography/25 Portal:Telecommunication/Selected biography/25 {{../box-footer|}}
