Lorenz Von Crell
Lorenz Florenz Friedrich von Crell (21 January 1744 – 7 June 1816) was a German chemist. In 1778 he started publishing the first periodical journal focusing on chemistry. The journal had a longer title, but was known simply as Crell's Annalen. Life and work Lorenz Crell was born in the Duchy of Brunswick's university town of Helmstedt as the son of medical professor Johann Friedrich Crell and grandchild of medical professor Lorenz Heister, who achieved renown in surgery and botany. At the age of fourteen, he entered the University of Helmstedt where, after nearly a decade of taking courses offered by the philosophical and medical faculties, he took his M.D. in 1768. He then made a two-year study tour to Göttingen, Strasbourg, Paris, Edinburgh, and London. In 1771, soon after his return to the Duchy of Brunswick, Crell secured appointment in Braunschweig's Collegium Carolinum as professor of metallurgy. Three years later, he relocated to the University of Helmstedt as professo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmstedt
Helmstedt (; Eastphalian: ''Helmstidde'') is a town on the eastern edge of the German state of Lower Saxony. It is the capital of the District of Helmstedt. The historic university and Hanseatic city conserves an important monumental heritage of Romanesque and Renaissance buildings, as well as numerous timber framed houses. During the German partition the nearby Bundesautobahn 2 was the site of the Helmstedt–Marienborn border crossing, the most important on the former inner German border as starting point of the shortest land route between West Germany and West Berlin. Geography Helmstedt is situated in a basin between the Elm and Lappwald hill ranges, at the transition area between the northern foothills of the Harz mountains and the North German Plain. It is surrounded by the Elm-Lappwald Nature Park. The town centre is located about east of Braunschweig, west of Magdeburg, and east of the state capital Hanover. The municipal area includes the localities of Barmke and E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phlogiston Theory
The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others. Phlogiston theory led to experiments which ultimately concluded with the discovery of oxygen. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlogiston and that they ''dephlogisticate'' when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Helmstedt Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

People From Brunswick-Lüneburg
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

19th-century German Chemists
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 Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duke Of Brunswick
Duke is a male title either of a monarch ruling over a duchy, or of a member of royalty, or nobility. As rulers, dukes are ranked below emperors, kings, grand princes, grand dukes, and sovereign princes. As royalty or nobility, they are ranked below princess nobility and grand dukes. The title comes from French ''duc'', itself from the Latin ''dux'', 'leader', a term used in republican Rome to refer to a military commander without an official rank (particularly one of Germanic or Celtic origin), and later coming to mean the leading military commander of a province. In most countries, the word ''duchess'' is the female equivalent. Following the reforms of the emperor Diocletian (which separated the civilian and military administrations of the Roman provinces), a ''dux'' became the military commander in each province. The title ''dux'', Hellenised to ''doux'', survived in the Eastern Roman Empire where it continued in several contexts, signifying a rank equivalent to a captain ...
