Charles Bourseul
Charles Bourseul (28 April 1829 – 23 November 1912) was a pioneer in development of the "make and break" telephone about 20 years before Bell made a practical telephone. Bourseul was born in Brussels, Belgium, and grew up in Douai, France. His father was a French army officer. Charles worked for the telegraph company as a civil engineer and mechanic. He made improvements to the telegraph system of L. F. Breguet (a French instrument maker) and Samuel F. B. Morse. Charles Bourseul experimented with the electrical transmission of the human voice and developed an electromagnetic microphone, but his telephone receiver was unable to convert electric current back into clear human voice sounds. In 1854 Bourseul wrote a memorandum on the transmission of the human voice by electric currents that was first published in a magazine L'Illustration (Paris), though no prototype was built. That is about the same time that Meucci later claimed to have created his first attempt at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statue Of Charles Bourseul In Saint-Cere
A statue is a free-standing sculpture in which the realistic, full-length figures of persons or animals are carved or cast in a durable material such as wood, metal or stone. Typical statues are life-sized or close to life-size; a sculpture that represents persons or animals in full figure but that is small enough to lift and carry is a statuette or figurine, whilst one more than twice life-size is a colossal statue. Statues have been produced in many cultures from prehistory to the present; the oldest-known statue dating to about 30,000 years ago. Statues represent many different people and animals, real and mythical. Many statues are placed in public places as public art. The world's tallest statue, ''Statue of Unity'', is tall and is located near the Narmada dam in Gujarat, India. Color Ancient statues often show the bare surface of the material of which they are made. For example, many people associate Greek classical art with white marble sculpture, but there is evidenc ...

Telephone
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from el, τῆλε (''tēle'', ''far'') and φωνή (''phōnē'', ''voice''), together meaning ''distant voice''. A common short form of the term is ''phone'', which came into use early in the telephone's history. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a ...

Alexander Graham Bell
Alexander Graham Bell (, born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born inventor, scientist and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf; profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Bell also had a strong influence on the National Geographic Society and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brussels
Brussels (french: Bruxelles or ; nl, Brussel ), officially the Brussels-Capital Region (All text and all but one graphic show the English name as Brussels-Capital Region.)

Douai
Douai (, , ,; pcd, Doï; nl, Dowaai; formerly spelled Douay or Doway in English) is a city in the Nord département in northern France. It is a sub-prefecture of the department. Located on the river Scarpe some from Lille and from Arras, Douai is home to one of the region's most impressive belfries. History Its site probably corresponds to that of a 4th-century Roman fortress known as Duacum. From the 10th century, the town was a romance fiefdom of the counts of Flanders. The town became a flourishing textile market centre during the Middle Ages, historically known as Douay or Doway in English. In 1384, the county of Flanders passed into the domains of the Dukes of Burgundy and thence in 1477 into Habsburg possessions. In 1667, Douai was taken by the troops of Louis XIV of France, and by the 1668 Treaty of Aix-la-Chapelle, the town was ceded to France.

Louis-François-Clement Breguet
Louis François Clément Breguet (22 December 1804 – 27 October 1883), was a French physicist and watchmaker, noted for his work in the early days of telegraphy Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas p .... Educated in Switzerland, Breguet was the grandson of Abraham-Louis Breguet, founder of the Breguet (watch), watch manufacturing company Breguet.

Samuel Morse
Samuel Finley Breese Morse (April 27, 1791 – April 2, 1872) was an American inventor and painter. After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs. He was a co-developer of Morse code and helped to develop the commercial use of telegraphy. Personal life Samuel F. B. Morse was born in Charlestown, Massachusetts, the first child of the pastor Jedidiah Morse (1761–1826), who was also a geographer, and his wife Elizabeth Ann Finley Breese (1766–1828). His father was a great preacher of the Calvinist faith and supporter of the Federalist Party. He thought it helped preserve Puritan traditions (strict observance of Sabbath, among other things), and believed in the Federalist support of an alliance with Britain and a strong central government. Morse strongly believed in education within a Federalist framework, alongside the instillation of Calvin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Philipp Reis
Johann Philipp Reis (; 7 January 1834 – 14 January 1874) was a self-taught German scientist and inventor. In 1861, he constructed the first ''make-and-break'' telephone, today called the Reis telephone. Early life and education Reis was born in Gelnhausen, Germany, the son of Marie Katharine (Glöckner) and Karl Sigismund Reis, a master baker. His father belonged to the Evangelical Lutheran church. Reis's mother died while he was an infant, and he was raised by his paternal grandmother, a well-read, intelligent woman. At the age of six Reis was sent to the common school of his home town of Gelnhausen. Here his talents attracted the notice of his instructors, who advised his father to extend his education at a higher college. His father died before Reis was ten years old. His grandmother and guardians placed him at Garnier's Institute, in Friedrichsdorf, where he showed a taste for languages, and acquired both French and English, as well as a stock of miscellaneous infor ...
