Franz Schulze
Franz Ferdinand Schulze (17 January 1815 – 14 April 1873) was a German professor of chemistry and microbiology who taught at the Royal Prussian State Agricultural Academy in Eldena and later at Rostock. He innovated analytical techniques, particularly making use of specially blown glass tubes. He examined questions such as spontaneous generation in his experiments. He was able to demonstrate that when air was bubbled through sulfuric acid, the resulting air did not produce any growth in carefully sterilized culture media. He translated James Finlay Weir Johnston, J. F. W. Johnston's ''Elements of Agricultural Chemistry and Geology'' (1841) into German. He coined the name of the wood component lignin in 1857. Life and work Schulze was born in Naumburg, second son of a craftsman. An uncle took care of him from the age of ten, and he grew up in Meissen where he went to school. He returned to Naumburg where he passed his abitur in 1832 and then went to study in Leipzig. Here he to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spontaneous Generation
Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. It was hypothesized that certain forms, such as fleas, could arise from inanimate matter such as dust, or that maggots could arise from dead flesh. The doctrine of spontaneous generation was coherently synthesized by Aristotle, who compiled and expanded the work of earlier natural philosophers and the various ancient explanations for the appearance of organisms. Spontaneous generation was taken as scientific fact for two millennia. Though challenged in the 17th and 18th centuries by the experiments of Francesco Redi and Lazzaro Spallanzani, it was not discredited until the work of the French chemist Louis Pasteur and the Irish physicist John Tyndall in the mid-19th century. Rejection of spontaneous generation is no longer controversial among biologists. By the middle of the 19th century, experiments by Pa ...

John Tyndall
John Tyndall FRS (; 2 August 1820 – 4 December 1893) was a prominent 19th-century Irish physicist. His scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO and what is now known as the greenhouse effect in 1859. Tyndall also published more than a dozen science books which brought state-of-the-art 19th century experimental physics to a wide audience. From 1853 to 1887 he was professor of physics at the Royal Institution of Great Britain in London. He was elected as a member to the American Philosophical Society in 1868. Early years and education Tyndall was born in Leighlinbridge, County Carlow, Ireland. His father was a local police constable, descended from Gloucestershire emigrants who settled in southeast Ireland around 1670. Tyndall attended the local schools (Ballinabranna Primary School) in County Carlow until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Schwann
Theodor Schwann (; 7 December 181011 January 1882) was a German physician and physiologist. His most significant contribution to biology is considered to be the extension of cell theory to animals. Other contributions include the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term "metabolism". Early life and education Theodor Schwann was born in Neuss on 7 December 1810 to Leonard Schwann and Elisabeth Rottels. Leonard Schwann was a goldsmith and later a printer. Theodor Schwann studied at the Dreikönigsgymnasium (also known as the Tricoronatum or Three Kings School), a Jesuit school in Cologne. Schwann was a devout Roman Catholic. In Cologne his religious instructor , a priest and novelist, emphasized the individuality of the human soul and the importance of free will. In 1829, Schwann enrolled at the University of Bonn in the premedical curriculum. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Greifswald
The University of Greifswald (; german: Universität Greifswald), formerly also known as “Ernst-Moritz-Arndt University of Greifswald“, is a public research university located in Greifswald, Germany, in the state of Mecklenburg-Western Pomerania. Founded in 1456 (teaching existed since 1436), it is one of the oldest universities in Europe, with generations of notable alumni and staff having studied or worked in Greifswald. As the fourth oldest university in present Germany, it was temporarily also the oldest university of the Kingdoms of Sweden (1648–1815) and Prussia (1815–1945), respectively. Approximately two-thirds of the 10,179 students are from outside the state, including international students from 90 countries all over the world. Due to the small-town atmosphere, the pronounced architectural presence of the alma mater across town, and the young, academic flair in the streets, Greifswald is often described as a "university with a town built around it" rather ...

Eilhard Mitscherlich
Eilhard Mitscherlich (; 7 January 179428 August 1863) was a German chemist, who is perhaps best remembered today for his discovery of the phenomenon of crystallographic isomorphism in 1819. Early life and work Mitscherlich was born at Neuende (now a part of Wilhelmshaven) in the Lordship of Jever, where his father was pastor. His uncle, Christoph Wilhelm Mitscherlich (1760–1854), professor at the University of Göttingen, was in his day a celebrated scholar. Eilhard Mitscherlich was educated at Jever by the historian Friedrich Christoph Schlosser, and in 1811 went to the University of Heidelberg devoting himself to philology, with an emphasis on the Persian language. In 1813 he went to Paris to seek permission to join the embassy which Napoleon I of France was establishing in Persia. The abdication of Napoleon Bonaparte in 1814 put an end to this, and Mitscherlich resolved to study medicine in order that he might enjoy that freedom of travel usually allowed in the East to ph ...
