Remigius Fresenius
Carl Remigius Fresenius (28 December 1818 – 11 June 1897), was a German chemist, known for his studies in analytical chemistry. Biography Fresenius was born on 28 December 1818, in Frankfurt, Germany. After working for some time for a pharmacy in his native town, he entered Bonn University in 1840, and a year later migrated to Gießen, where he acted as assistant in Liebig's laboratory, and in 1843, became an assistant professor. In 1845, he was appointed to the chair of chemistry, physics and technology at the Wiesbaden Agricultural Institution, and three years later, he became the first director of the chemical laboratory which he induced the Nassau government to establish at that place. Under his leadership and direction, this laboratory continuously increased in size and popularity, a school of pharmacy being added in 1862 (though given up in 1877) and an agricultural research laboratory in 1868. Apart from his administrative duties, Fresenius occupied himself almost exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free City Of Frankfurt
Frankfurt was a major city of the Holy Roman Empire, being the seat of imperial elections since 885 and the city for Coronation of the Holy Roman emperor, imperial coronations from 1562 (previously in Free Imperial City of Aachen) until 1792. Frankfurt was declared an Imperial Free City (''Freie und Reichsstadt'') in 1372, making the city an entity of Imperial immediacy, meaning immediately subordinate to the Holy Roman Emperor and not to a regional ruler or a local nobleman. Due to its imperial significance, Frankfurt survived German Mediatisation, mediatisation in 1803. Following the collapse of the Holy Roman Empire in 1806, Frankfurt fell to the rule of Napoleon I, who granted the city to Karl Theodor Anton Maria von Dalberg; the city became known as the Principality of Frankfurt. The Catholic cleric Dalberg emancipated Catholics living with the city boundary. In 1810 Dalberg merged Frankfurt with the Principality of Aschaffenburg, the County of Wetzlar, Fulda, and Hanau to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolph Wilhelm Hermann Kolbe
Adolph Wilhelm Hermann Kolbe (27 September 1818 – 25 November 1884) was a German chemist and academic, and a major contributor to the birth of modern organic chemistry. He was a professor at Marburg and Leipzig. Kolbe was the first to apply the term synthesis in a chemical context, and contributed to the philosophical demise of vitalism through synthesis of the organic substance acetic acid from carbon disulfide, and also contributed to the development of structural theory. This was done via modifications to the idea of "radicals" and accurate prediction of the existence of secondary and tertiary alcohols, and to the emerging array of organic reactions through his Kolbe electrolysis of carboxylate salts, the Kolbe-Schmitt reaction in the preparation of aspirin and the Kolbe nitrile synthesis. After studies with Wöhler and Bunsen, Kolbe was involved with the early internationalization of chemistry through work in London (with Frankland). He was elected to the Royal Swedish A ...

University Of Bonn Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in th ...

19th-century German Chemists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was Abolitionism, abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, 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 Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems an ...
