Caroline Eichler
Margarethe Caroline Eichler (born in 1808 or 1809; died 6 September 1843 in Berlin) was a German inventor, instrument maker and prostheses designer. She was the first woman in Prussia to receive a patent (for her leg prosthesis) and was also the inventor of the first practical modern hand prosthesis. Biography Caroline Eichler was born in 1808 or 1809, presumably in Nordhausen or Berlin, as the third daughter of painter Johann Gottlieb Eichler. In those days, young women were usually denied higher education opportunities or apprenticeships, and although no documentation has been found describing her schooling, her work demonstrates a knowledge of physics and technical mechanics. Around 1826 Eichler was working as a nanny and later worked as a nurse. Life While working as a nurse, Eichler was struck by the misery of amputees and "found myself particularly stimulated when, in the course of my business of nursing, I noticed the manifold sufferings of such unfortunate people.

Prussia
Prussia, , Old Prussian: ''Prūsa'' or ''Prūsija'' was a German state on the southeast coast of the Baltic Sea. It formed the German Empire under Prussian rule when it united the German states in 1871. It was ''de facto'' dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and ''de jure'' by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. In 1871, Prussian Minister-President Otto von Bismarck united most German principalities into the German Empire under his leadership, although this was considered to be a "Lesser Germany" because Austria and Switzerland were not included. In November 1918, the monarchies were abolished and the nobility lost its political power during the Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Götz Von Berlichingen
Gottfried "Götz" von Berlichingen (1480 – 23 July 1562), also known as Götz of the Iron Hand, was a German (Franconian) Imperial Knight (''Reichsritter''), mercenary, and poet. He was born around 1480 into the noble family of Berlichingen in modern-day Baden-Württemberg. Götz bought Hornberg Castle (Neckarzimmern) in 1517, and lived there until his death in 1562. He was active in numerous military campaigns during a period of 47 years from 1498 to 1544, including the German Peasants' War, besides numerous feuds; in his autobiography he estimates that he fought 15 feuds in his own name, besides many cases where he lent assistance to his friends, including feuds against the cities of Cologne, Ulm, Augsburg and the Swabian League, as well as the bishop of Bamberg. His name became famous as a euphemism for a vulgar expression ('' Er kann mich am Arsch lecken'' – "Gruaisenffith") attributed to him by writer and poet Johann Wolfgang von Goethe (1749–1832), who wrote ...

19th-century German Women Scientists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inventors
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thaler
A thaler (; also taler, from german: Taler) is one of the large silver coins minted in the states and territories of the Holy Roman Empire and the Habsburg monarchy during the Early Modern period. A ''thaler'' size silver coin has a diameter of about and a weight of about 25 to 30 grams (roughly 1 ounce). The word is shortened from ''Joachimsthaler'', the original ''thaler'' coin minted in Joachimstal, Bohemia, from 1520. While the first standard coin of the Holy Roman Empire was the ''Guldengroschen'' of 1524, its longest-lived coin was the ''Reichsthaler (Reichstaler)'', which contained Cologne Mark of fine silver (or 25.984 g), and which was issued in various versions from 1566 to 1875. From the 17th century a lesser-valued ''North German thaler'' currency unit emerged, which by the 19th century became par with the ''Vereinsthaler''. The ''thaler'' silver coin type continued to be minted until the 20th century in the form of the Mexican peso until 1914, the five S ...

Thumb
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: # Any of the five terminal members of the hand. # Any of the four terminal members of the hand, other than the thumb Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Hand (prosthesis)
Iron hands are metal prosthesis, prostheses for hands and upper extremities from the middle ages and early modern period. These designs combined cosmetic and functional properties. The most famous example of an iron hand was made around the year 1530, being the second prosthetic hand made for the German knight Götz von Berlichingen.Quasigroch, Günter: ''Die Handprothesen des fränkischen Reichsritters Götz von Berlichingen. 2. Fortsetzung: Die Zweithand.'' In: ''Waffen- und Kostümkunde.'' Vol. 25, 1983, pp. 103–120. Most iron hands are based on the same constructive principles, although there are considerable differences in complexity. Fingers can be Anatomical terms of motion#Flexion and extension, flexed passively (for example using the healthy hand) and are locked in place by a Ratchet (device), ratchet mechanism, similar to those of contemporary Flintlock mechanism, flintlocks.

Nordhausen, Thuringia
Nordhausen () is a city in Thuringia, Germany. It is the capital of the Nordhausen district and the urban centre of northern Thuringia and the southern Harz region; its population is 42,000. Nordhausen is located approximately north of Erfurt, west of Halle, south of Braunschweig and east of Göttingen. Nordhausen was first mentioned in records in the year 927 and became one of the most important cities in central Germany during the later Middle Ages. The city is situated on the Zorge river, a tributary of the Helme within the fertile region of Goldene Aue ''(golden floodplain)'' at the southern edge of the Harz mountains. In the early 13th century, it became a free imperial city, so that it was an independent and republican self-ruled member of the Holy Roman Empire. Due to its long-distance trade, Nordhausen was prosperous and influential, with a population of 8,000 around 1500. It was the third-largest city in Thuringia after Erfurt, today's capital, and Mühlhausen, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
