Émile Baudot
Jean-Maurice-Émile Baudot (; 11 September 1845 – 28 March 1903), French telegraph engineer and inventor of the first means of digital communication Baudot code, was one of the pioneers of telecommunications. He invented a multiplexed printing telegraph system that used his code and allowed multiple transmissions over a single line. The baud unit was named after him. Early life Baudot was born in Magneux, Haute-Marne, France, the son of farmer Pierre Émile Baudot, who later became the mayor of Magneux. His only formal education was at his local primary school, after which he carried out agricultural work on his father's farm before joining the French Post & Telegraph Administration as an apprentice operator in 1869. The telegraph service trained him in the Morse telegraph and also sent him on a four-month course of instruction on the Hughes printing telegraph system, which was later to inspire his own system. After serving briefly during the Franco-Prussian War, he r ...

Lorient
Lorient (; ) is a town (''Communes of France, commune'') and Port, seaport in the Morbihan Departments of France, department of Brittany (administrative region), Brittany in western France. History Prehistory and classical antiquity Beginning around 3000 BC, settlements in the area of Lorient are attested by the presence of Megalith, megalithic architecture. Ruins of Roman roads (linking Vannes to Quimper and Port-Louis, Morbihan, Port-Louis to Carhaix) confirm Gallo-Roman presence. Founding In 1664, Jean-Baptiste Colbert founded the Louis XIV's East India Company, French East Indies Company. In June 1666, an Ordonnance, ordinance of Louis XIV of France, Louis XIV granted lands of Port-Louis, Morbihan, Port-Louis to the company, along with Faouédic on the other side of the roadstead. One of its directors, Denis Langlois, bought lands at the confluence of the Scorff and the Blavet rivers, and built slipways. At first, it only served as a subsidiary of Port-Louis, where o ...

Vannes
Vannes (; , , ) is a Communes of France, commune in the Departments of France, French department of Morbihan, Brittany (administrative region), Brittany, northwestern mainland France. It was founded over 2,000 years ago. History Celtic Era The name ''Vannes'' comes from the Veneti (Gaul), Veneti, a seafaring Celts, Celtic people who lived in the south-western part of Armorica in Gaul before the Ancient Rome, Roman invasions. The region seems to have been involved in a cross channel trade for thousands of years, probably using hide boats and perhaps Ferriby Boats. Wheat that apparently was grown in the Middle East was part of this trade. At about 150 BC the evidence of trade (such as Gallo-Belgic coins) with the Thames estuary area of Great Britain dramatically increased. Roman Era The Veneti were defeated by Julius Caesar's fleet in 56 BC in front of Locmariaquer; many of the Veneti were then either slaughtered or sold into slavery. The Romans settled a town called ...

Weston-super-Mare
Weston-super-Mare ( ) is a seaside town and civil parish in the North Somerset unitary district, in the county of Somerset, England. It lies by the Bristol Channel south-west of Bristol between Worlebury Hill and Bleadon Hill. Its population at the 2021 census was 82,418. The area around the town has been occupied since the Iron Age. It was still a small village until the 19th century when it developed as a seaside resort. A Weston-super-Mare railway station, railway station and two piers were built. In the second half of the 20th century it was connected to the M5 motorway but the number of people holidaying in the town declined and some local industries closed, although the number of day visitors has risen.

Punched Tape
file:PaperTapes-5and8Hole.jpg, Five- and eight-hole wide punched paper tape file:Harwell-dekatron-witch-10.jpg, Paper tape reader on the Harwell computer with a small piece of five-hole tape connected in a circle – creating a physical program loop Punched tape or perforated paper tape is a form of data storage that consists of a long strip of paper through which small holes are punched. It was developed from and was subsequently used alongside punched cards, the difference being that the tape is continuous. Punched cards, and chains of punched cards, were used for control of looms in the 18th century. Use for telegraphy systems started in 1842. Punched tapes were used throughout the 19th and for much of the 20th centuries for programmable looms, teleprinter communication, for input to computers of the 1950s and 1960s, and later as a storage medium for minicomputers and Numerical control, CNC machine tools. During the Second World War, high-speed punched tape systems using opti ...

Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire (likely copper) wound into a electromagnetic coil, coil. A current through the wire creates a magnetic field which is concentrated along the center of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet, which needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field. Electromagnets are widely used as components of other electrical devices, such as Electric motor, motor ...

Multiplexing
In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource—a physical transmission medium. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a ...

Wilhelm Eduard Weber
Wilhelm Eduard Weber ( ; ; 24 October 1804 – 23 June 1891) was a German physicist and, together with Carl Friedrich Gauss, inventor of the first electromagnetic telegraph. Biography Early years Weber was born in Schlossstrasse in Wittenberg, where his father, Michael Weber, was Professor of Theology at the local university. The building in which they lived had previously been the home of Abraham Vater. Wilhelm was the second of three brothers, all of whom were distinguished by an aptitude for science. After the University of Halle-Wittenberg#History, dissolution of the University of Wittenberg in 1817, his father was transferred to the university in Halle, Saxony-Anhalt, Halle. Wilhelm had received his first lessons from his father, but was now sent to the Orphan Asylum and Grammar School in Halle. After that he entered the university and devoted himself to natural philosophy. He distinguished himself so much in his classes, and by original work, that after taking his ...

Carl Friedrich Gauss
Johann Carl Friedrich Gauss (; ; ; 30 April 177723 February 1855) was a German mathematician, astronomer, geodesist, and physicist, who contributed to many fields in mathematics and science. He was director of the Göttingen Observatory and professor of astronomy from 1807 until his death in 1855. While studying at the University of Göttingen, he propounded several mathematical theorems. As an independent scholar, he wrote the masterpieces '' Disquisitiones Arithmeticae'' and ''Theoria motus corporum coelestium''. Gauss produced the second and third complete proofs of the fundamental theorem of algebra. In number theory, he made numerous contributions, such as the composition law, the law of quadratic reciprocity and the Fermat polygonal number theorem. He also contributed to the theory of binary and ternary quadratic forms, the construction of the heptadecagon, and the theory of hypergeometric series. Due to Gauss' extensive and fundamental contributions to science ...
