Friedrich Von Knauss
Friedrich von Knaus(s) (February 7 or April 7, 1724 - August 14, 1789), was a German watchmaker and inventor who built clockwork mechanisms which could, in a simple way, play musical instruments, write short phrases, or conduct other individual, specialized tasks. Von Knauss was born either in Aldingen or in Ludwigsburg. His father, Ludwig Knaus, was also a watchmaker. Friedrich had a brother, Ludwig Johann, whose year of birth is said to have been 1715 or 1716. From 1739 into the 1750s, von Knauss was busy with the Darmstadt great duke's court, and in 1749 he became "Hofmechaniker", Imperial and Royial Court Mechanician. Together with his brother he produced the famous ''Kaiserliche Vorstellungsuhr'' (the Imperial Representation Watch) in 1750, commemorating the tenth anniversary of Maria Theresia's rise to the throne. In 1757, he completed work on a mechanical musician that played the flageolet, a kind of recorder.Metzner, Paul. Crescendo of the Virtuoso: Spectacle, Skill, and ...

Clockwork
Clockwork refers to the inner workings of either mechanical devices called clocks and watches (where it is also called the movement) or other mechanisms that work similarly, using a series of gears driven by a spring or weight. A clockwork mechanism is often powered by a clockwork motor, description of the clockwork motor in an antique phonograph consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by ''winding it up'', turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until the stored energy is used up. The adjectives ''wind-up'' and ''spring-powered'' refer to mainspring-powered clockwork devices, which include clocks and watches, kitchen timers, music boxes, and wind-up toys. History The earliest known example of a clockwork mechanism is the Antikythera mechanism, a first-century BC geared analogue computer, somewhat astrolabe-li ...

Musical Instrument
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 50,000 - 60,000 years. Some consensus dates early flutes to about 40,000 years ago. However, most historians be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remseck
Remseck am Neckar () is a town in the district of Ludwigsburg, Baden-Württemberg, Germany. It is situated at the confluence of the rivers Rems and Neckar, about 12 km northeast of Stuttgart, and 7 km southeast of Ludwigsburg. The town was formed on January 1, 1975, initially under the name Aldingen am Neckar. In 1977, it received the name Remseck am Neckar and has had the status of a Große Kreisstadt since January 1, 2004. History Five of the six boroughs of Remseck used to be villages and were founded several hundred years ago. References to Aldingen and Hochdorf can be found as early as 1100, Hochberg is mentioned in a text from 1231 whereas Neckargröningen is already referred to in 806. Neckarrems is also mentioned in 1268 as „Rems“; the „Neckar“ was added only in the 17th century. Hochdorf, Hochberg, and Neckarrems used to belong to Waiblingen, whereas Aldingen und Neckargröningen belonged to Ludwigsburg. In 1938 however, all five boroughs were assign ...

Ludwigsburg
Ludwigsburg (; Swabian: ''Ludisburg'') is a city in Baden-Württemberg, Germany, about north of Stuttgart city centre, near the river Neckar. It is the largest and primary city of the Ludwigsburg district with about 88,000 inhabitants. It is situated within the '' Stuttgart Region'', and the district is part of the administrative region (''Regierungsbezirk'') of Stuttgart. History The middle of Neckarland, where Ludwigsburg lies, was settled in the Stone and Bronze Ages. Numerous archaeological sites from the Hallstatt period remain in the city and surrounding area. Towards the end of the 1st century, the area was occupied by the Romans. They pushed the Limes further to the east around 150 and controlled the region until 260, when the Alamanni occupied the Neckarland. Evidence of the Alamanni settlement can be found in grave sites in the city today. The origins of Ludwigsburg date from the beginning of the 18th century (1718–1723) when the largest baroque castle i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mechanician
A mechanician is an engineer or a scientist working in the field of mechanics, or in a related or sub-field: engineering or computational mechanics, applied mechanics, geomechanics, biomechanics, and mechanics of materials. Names other than mechanician have been used occasionally, such as mechaniker and mechanicist. The term mechanician is also used by the Irish Navy to refer to junior engine room ratings. In the United Kingdom, British Royal Navy, Chief Mechanicians and Mechanicians 1st Class were Chief Petty Officers, Mechanicians 2nd and 3rd Class were Petty Officers, Mechanicians 4th Class were Leading Ratings, and Mechanicians 5th Class were Able Ratings. The rate was only applied to certain technical specialists and no longer exists. In the New Zealand Post Office, which provided telephone service prior to the formation of Telecom New Zealand in 1987, "Mechanician" was a job classification for workers who serviced telephone exchange switching equipment. The term seems to hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maria Theresia
Maria Theresa Walburga Amalia Christina (german: Maria Theresia; 13 May 1717 – 29 November 1780) was ruler of the Habsburg dominions from 1740 until her death in 1780, and the only woman to hold the position ''suo jure'' (in her own right). She was the sovereign of Austria, Hungary, Croatia, Bohemia, Transylvania, Mantua, Milan, Lodomeria and Galicia, the Austrian Netherlands, and Parma. By marriage, she was Duchess of Lorraine, Grand Duchess of Tuscany and Holy Roman Empress. Maria Theresa started her 40-year reign when her father, Emperor Charles VI, died on 20 October 1740. Charles VI paved the way for her accession with the Pragmatic Sanction of 1713 and spent his entire reign securing it. He neglected the advice of Prince Eugene of Savoy, who believed that a strong military and a rich treasury were more important than mere signatures. Eventually, Charles VI left behind a weakened and impoverished state, particularly due to the War of the Polish Succession and the Russo ...

Flageolet
The flageolet is a woodwind instrument and a member of the fipple flute family which includes recorders and tin whistles. Its invention was erroneously ascribed to the 16th-century Sieur Juvigny in 1581. There are two basic forms of the instrument: the French, having four finger holes on the front and two thumb holes on the back; and the English, having six finger holes on the front and sometimes a single thumb hole on the back. The latter was developed by English instrument maker William Bainbridge, resulting in the "improved English flageolet" in 1803. There are also double and triple flageolets, having two or three bodies that allowed for a drone and countermelody. Flageolets were made until the 19th century. Flageolets have varied greatly during the last 400 years. The first flageolets were called "French flageolets", and have four tone-holes on the front and two on the back. This instrument was played by Hector Berlioz, Frédéric Chalon, Samuel Pepys, and Robert Louis Steve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recorder (musical Instrument)
The recorder is a family of woodwind musical instruments in the group known as ''internal duct flutes'': flutes with a whistle mouthpiece, also known as fipple flutes. A recorder can be distinguished from other duct flutes by the presence of a thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition. Recorders are made in various sizes with names and compasses roughly corresponding to various vocal ranges. The sizes most commonly in use today are the soprano (also known as descant, lowest note C5), alto (also known as treble, lowest note F4), tenor (lowest note C4), and bass (lowest note F3). Recorders were traditionally constructed from wood or ivory. Modern professional instruments are almost invariably of wood, often boxwood; student and scholastic recorders are commonly of molded plastic. The recorders' internal and external proportions vary, but the bore i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
