Ulrich Grubenmann
Johann Ulrich Grubenmann (15 April 1850 – 16 March 1924) was a Swiss mineralogist and petrologist who served as professor of geology at the Swiss Federal Institute of Technology (now ETH Zurich) . He studied metamorphism and produced an influential classification of metamorphic rocks. Life and work Grubenmann was born in Trogen, Switzerland, Trogen, Switzerland to baker Johann Kaspar Grubenmann and Katharina Eugster. His ancestors included the bridge-builder Johann Ulrich Grubenmann (1709-1783) who constructed a famous wooden bridge at Schaffhausen. Growing in a family of limited means, Grubenmann was able to study with scholarships and help from friends and became a certified teacher of natural sciences in 1874. He received a PhD for studies on the basalts of Hegau in 1886 from the University of Zurich. He then taught at the Swiss Federal Institute of Technology and at the Canton School in Frauenfeld. He became Privatdozent in 1888 and replaced Gustav Adolph Kenngott in 1897 as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gustav Adolph Kenngott
Gustav Adolph Kenngott (January 6, 1818 – March 7, 1897) was a German mineralogist. Biography Kenngott was born in Breslau. After being employed in the Hofmineralien-Cabinett at Vienna. From 1857 to 1893 he was also full professor of mineralogy at the ETH Zurich and at the University of Zürich. He was distinguished for his researches on mineralogy, crystallography and petrology. In 1855, from the serpentine of Mount Zdjar near Schönberg in Moravia, Kenngott was the first to describe enstatite. In 1860 he identified a new mineral, giving it the name pisanite in honor of Felice Pisani. Kenngott died in Lugano.

Hegau
The Hegau is an extinct volcanic landscape in southern Germany extending around the industrial city of Singen (Hohentwiel), between Lake Constance in the east, the Rhine River in the south, the Danube River in the north and the Randen—as the southwestern mountains of the Swabian Jura are called—in the west. It was first mentioned in A.D. 787 in the Latinised form ''in pago Egauinsse''.Albert Krieger: Topographisches Wörterbuch des Großherzogtums Baden, Vol. 1, p. 882 (1904)' The most famous sight of the Hegau is the Hohentwiel Hohentwiel is an extinct volcano in the Hegau region of Baden-Württemberg in southern Germany The mountain is west of the city of Singen and 20 miles (30 km) from Lake Constance.

Paul Niggli
Paul Niggli (26 June 1888 – 13 January 1953) was a Swiss crystallographer, mineralogist, and petrologist who was a leader in the field of X-ray crystallography. Education and career Niggli was born in Zofingen and studied at the Swiss Federal Institute of Technology (ETH) in Zurich and the University of Zurich, where he obtained a doctorate. His 1919 book, ''Geometrische Kristallographie des Diskontinuums'', played a seminal role in the refinement of space group theory. In this book, Niggli demonstrated that although X-ray reflection conditions do not always uniquely determine the space group to which a crystal belongs, they do reveal a small number of possible space groups to which it could belong. Niggli used morphological methods to account for internal structure and, in his 1928 ''Kristallographische und Strukturtheoretische Grundbegriffe,'' he took up what is essentially the reverse process, the task of establishing the connection between space lattices and external cry ...

1850 Births
Year 185 ( CLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

19th-century Swiss Geologists
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] |
Academic Staff Of ETH Zurich
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
