Life and work Weisbach studied at the '' Bergakademie'' in Freiberg from 1822 - 1826. After that, he studied with Carl Friedrich Gauss in Göttingen and with Friedrich Mohs in Vienna. In 1831 he returned to Freiberg where he worked as mathematics teacher at the local Gymnasium. In 1833 he became teacher for Mathematics and the Theory of Mountain Machines at the Freiberg ''Bergakademie''. In 1836 he was promoted to Professor for applied mathematics, mechanics, theory of mountain machines and so-called ''Markscheidekunst''. Weisbach wrote an influential book for mechanical engineering students, called ''Lehrbuch der Ingenieur- und Maschinenmechanik'', which has been expanded and reprinted on numerous occasions between 1845 and 1863.

University Of Göttingen Alumni
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 (''UniversitĂ 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 ...

Engineers From Saxony
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

19th-century German Mathematicians
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] |
Clemens Winkler
Clemens Alexander Winkler (December 26, 1838 – October 8, 1904) was a German chemist who discovered the element germanium in 1886, solidifying Dmitri Mendeleev's theory of periodicity. Life Winkler was born in 1838 in Freiberg, Kingdom of Saxony the son of a chemist who had studied under Berzelius. Winkler's early education was at schools in Freiberg, Dresden, and Chemnitz. In 1857 he entered the Freiberg University of Mining and Technology, where his knowledge of analytical chemistry surpassed what he was being taught there. Sixteen years later, Winkler was appointed a professor of chemical technology and analytical chemistry at the university. Winkler was elected a member of the Royal Swedish Academy of Sciences in 1892. In 1893, Winkler moved to Hamburg where he married his childhood sweetheart Tanja Braun. In 1902, Winkler resigned his professorship. He died in Dresden two years later of carcinoma at the age of 65. According to Brunck, Winkler wrote poetry, an ...

Mary Hegeler Carus
Mary Hegeler Carus (January 10, 1861 – June 27, 1936) was an American engineer, editor and entrepreneur. In 1882 she was the first woman to graduate in engineering from the University of Michigan. Early life Marie Hermine Henriette Hegeler was born on January 10, 1861, in La Salle, Illinois, the first of ten children born to German immigrants, Edward Carl Hegeler (1835–1910), and Camilla Weisbach Hegeler (1835–1908), daughter of Freiberg professor Julius Weisbach (1806–1871). The couple had met during Hegeler's studies at the Bergakademie Freiberg, and they married in 1860. Edward Carl Hegeler set up and ran the Matthiessen-Hegeler Zinc Company in La Salle with his college friend Frederick William Matthiessen. At one time the company was the largest producer of zinc in the US. As a child, Mary Hegeler was interested in her father's zinc smelter and in how smelting furnaces worked. She was her father's constant companion in the works, becoming expert at reading t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matthiessen And Hegeler Zinc Company
The Mattheissen and Hegeler (M&H) Zinc Company was a zinc manufacturing company headquartered in LaSalle, Illinois. At one time, the family-owned company was the largest zinc manufacturing plant in the United States. The company brought zinc ore from Wisconsin and Missouri to the coal fields of Northern Illinois. The company and its founders had a large influence in the development of LaSalle & Peru, Illinois. History Frederick Matthiessen and Edward Hegeler met while studying at the School of Mines in Freiberg, Saxony. They identified that the United States did not have a strong zinc industry and felt it was an opportunity. They were also interested in iron, coal, and zinc exporting. The pair sailed from Germany to Boston in 1856 and studied several sites in Pennsylvania, Missouri, and Wisconsin. Zinc ore had been discovered at Mineral Point, Wisconsin and they selected LaSalle, Illinois as the location for their plant due to its coal fields, since it required about two ...
