Lazarus Ercker
Lazarus Ercker (c. 1530 – 1594) was a Bohemian Metallurgy, metallurgist and assay master of a mint near Prague, Prague, Bohemia who wrote some of the earliest known treatises on metallurgy entitled ''Beschreibung allerfürnemisten mineralischen Ertzt und Berckwercksarten'' (1574) and ''Münzbuch, wie es mit den Münzen gehalten sind'' (1563). Life Ercker was born at St. Annenberg (Annaberg-Buchholz, Annaberg, Saxony) around 1530 and studied at the University of Wittenberg between 1547 and 1548. Around 1554 he became an assayer at Dresden through the patronage of Augustus, Elector of Saxony, Elector Augustus with the influence of Johann Neese (a relative of his wife). In 1558 he became master of the mint at Goslar for Prince Henry of Brunswick. In 1567 his wife died and he tried to return to Dresden.

Bohemia
Bohemia ( ; ; ) is the westernmost and largest historical region of the Czech Republic. In a narrow, geographic sense, it roughly encompasses the territories of present-day Czechia that fall within the Elbe River's drainage basin, but historically it could also refer to a wider area consisting of the Lands of the Bohemian Crown ruled by the List of Bohemian monarchs, Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia Proper as a means of distinction. Bohemia became a part of Great Moravia, and then an independent principality, which became a Kingdom of Bohemia, kingdom in the Holy Roman Empire. This subsequently became a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an History of Czechoslovakia (1918–1938), independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German ...

Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...

16th-century People From Bohemia
The 16th century began with the Julian calendar, Julian year 1501 (represented by the Roman numerals MDI) and ended with either the Julian or the Gregorian calendar, Gregorian year 1600 (MDC), depending on the reckoning used (the Gregorian calendar introduced a lapse of 10 days in October 1582). The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the Copernican heliocentrism, heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the SN 1572, 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science. Galileo Galilei became a champion of the new sciences, invented the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgists
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Pettus (courtier)
Sir John Pettus (1613–1690) was an English royalist, politician and natural philosopher. Pettus was an expert on metallurgy and became a deputy governor of the royal mines in England and Wales under Charles I and II. He is known for the first English translation of the work of the German metallurgist Lazarus Ercker. Life He was the third son of Sir Augustine Pettus of Rackheath, Norfolk, by his second wife, Abigail, third daughter of Sir Arthur Heveningham of Heveningham, Suffolk. He matriculated at Pembroke College, Cambridge in 1632. He entered the service of Charles I in 1639, and was knighted on 25 November 1641, as a mark of the king's favour to Sir Richard Gurney, his father-in-law. Taken prisoner during the First English Civil War by Oliver Cromwell at Lowestoft, he was exchanged after 14 months' confinement in Windsor Castle. Pettus then raised a regiment of horse, at his own expense; but moved on to garrison work, at Bath and Bristol. At the 1645 siege of Bristol hi ...

He was a member of the House of Habsburg. Rudolf's legacy has traditionally been viewed in three ways:Hotson, 1999. an ineffectual ruler whose mistakes led directly to the Thirty Years' War; a great and influential patron of Northern Mannerism, Northern Mannerist art; and an intellectual devotee of occult arts and learning which helped seed what would be called the Scientific Revolution. Determined to unify Christendom, he initiated the Long Turkish War (1593–1606) with the Ottoman Empire. Exhausted by war, his citizens in Kingdom of Hungary (1526-1867), Hungary revolted in the Bocskai uprising, Bocskai Uprising, which led to more authority being given to his brother Matthias, Holy Roman Emperor, Matthias.

Kutná Hora
Kutná Hora (; ) is a town in the Central Bohemian Region of the Czech Republic. It has about 22,000 inhabitants. The history of Kutná Hora is linked to silver mining, which made it a rich and rapidly developing town. The centre of Kutná Hora, including the Sedlec Abbey and the Sedlec Ossuary, was designated a UNESCO World Heritage Site in 1995 because of its outstanding architecture and its influence on subsequent architectural developments in other Central European city centres. The historic town centre is also protected as an Cultural monument (Czech Republic)#Monument reservations, urban monument reservation, the fourth largest in the Czech Republic.

Augustus, Elector Of Saxony
Augustus (31 July 152611 February 1586) was Elector of Saxony from 1553 to 1586. First years Augustus was born in Freiberg, the youngest child and third (but second surviving) son of Henry IV, Duke of Saxony, and Catherine of Mecklenburg. He consequently belonged to the Albertine branch of the House of Wettin. Brought up as a Lutheran, he received a good education and studied at Leipzig University. When Duke Henry IV died in 1541, he decreed that his lands should be divided equally between his two sons; but as his bequest was contrary to the Albertine Law, it was not carried out, and the dukedom passed almost intact to his elder son, Maurice. Augustus, however, remained on friendly terms with his brother, and to further his policy spent some time at the court of Ferdinand I, Holy Roman Emperor, in Vienna. In 1544, Maurice secured the appointment of his brother as administrator of the bishopric of Merseburg; but Augustus was very extravagant and was soon compelled to return ...
