Walthère Victor Spring
Walthère Victor Spring (6 March 1848 – 17 July 1911) was a Belgian experimental chemist and a professor at the University of Liège who contributed to ideas on carbon dioxide in the atmosphere and the Greenhouse Effect. As a physical chemist he demonstrated the formation of certain compounds such as metal sulphides under high pressure conditions. He also took an interest in the study of the Tyndall effect and examined the cause of the colour of the sky and water. Spring was born in Liège to physician and professor of medicine, Antoine Spring (1814–1872) who was of Bavarian ancestry. He experimented in physics and chemistry but studied classical languages and humanities at the Athenaeum. He failed the examination to enter university but took an interest in practical work. He worked for a while with an arms manufacturer in Liège but was encouraged by the chemist Jean-Servais Stas (1813–1891) to study and he joined the Mining School from where he received a diploma in 1871. ...

Walter Spring
Walter Spring the Unfortunate (1620 – c.1678) was an Anglo-Irish Roman Catholic landowner involved in the Irish Confederate Wars. Biography Spring was the son of Thomas Spring, a lawyer. He was the grandson of Walter Spring, who had served as High Sheriff of Kerry, and the great-grandson of Captain Thomas Spring, Constable of Castlemaine. He inherited the family estates in County Kerry from his father, including Killagha Abbey, where he was born and brought up. Unlike the previous generations of his family, Walter Spring was raised as a Catholic. His control of the strategic fortress at Castlemaine and the lands surrounding Milltown made him an important figure in Kerry. He attended the 1642 Kilkenny meeting of Catholic gentry which established the Association of the Confederate Catholics of Ireland and was active in helping to organise the war effort on behalf of the Catholic rebels. During the Cromwellian conquest of Ireland, Spring’s fortified manor house at Killagha A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Liège
The University of Liège (french: Université de Liège), or ULiège, is a major public university of the French Community of Belgium based in Liège, Wallonia, Belgium. Its official language is French. As of 2020, ULiège is ranked in the 301–350 category worldwide according to ''Times Higher Education'', 451st by ''QS World University Rankings'', and between the 201st and 300th place by the '' Academic Ranking of World Universities''. More than 2,000 people, including academics, scientists and technicians, are involved in research of a wide variety of subjects from basic research to applied research. History The university was founded in 1817 by William I of the Netherlands, then King of the United Kingdom of the Netherlands, and by his Minister of Education, Anton Reinhard Falck. The foundation of the university was the result of a long intellectual tradition which dates back to the origins of the Prince-Bishopric of Liège. Beginning in the eleventh century, the influenc ...

Antoine Frédéric Spring
Antoine Frédéric Spring (8 April 1814 in Gerolsbach, Bavaria – 17 January 1872) was a German-born, Belgian physician and botanist. He studied botany and medicine at the University of Munich, obtaining his PhD in 1835 and his medical doctorate during the following year. From 1839 to 1872 he was a professor at the University of Liège, initially in the fields of physiology and anatomy, later teaching classes in pathology and internal medicine. As a botanist he specialized in research of Lycopodiaceae (clubmosses) and Selaginellaceae (spikemosses), and was the binomial author of numerous species from both families.

Jean Stas
Jean Servais Stas (21 August 1813 – 13 December 1891) was a Belgian analytical chemist who co-discovered the atomic weight of carbon. Life and work Stas was born in Leuven and trained initially as a physician. He later switched to chemistry and worked at the École Polytechnique in Paris under the direction of Jean-Baptiste Dumas. Stas and Dumas established the atomic weight of carbon by weighing a sample of the pure material, burning it in pure oxygen, and then weighing the carbon dioxide produced. In 1840, Stas was appointed professor at the Royal Military School in Brussels. He acquired international fame by determining the atomic weights of the elements more accurately than had ever been done before, using an atomic mass of 16 for oxygen as his standard. His results disproved the hypothesis of the English physicist William Prout that all atomic weights must be integer multiples of that of hydrogen. These careful, accurate atomic weight measurements of Stas helped lay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Kekulé
Friedrich August Kekulé, later Friedrich August Kekule von Stradonitz ( , ; 7 September 1829 – 13 July 1896), was a German organic chemist. From the 1850s until his death, Kekulé was one of the most prominent chemists in Europe, especially in theoretical chemistry. He was the principal founder of the theory of chemical structure and in particular the Kekulé structure of benzene. Name Kekulé never used his first given name; he was known throughout his life as August Kekulé. After he was ennobled by the Kaiser in 1895, he adopted the name August Kekule von Stradonitz, without the French acute accent over the second "e". The French accent had apparently been added to the name by Kekulé's father during the Napoleonic occupation of Hesse by France, to ensure that French-speaking people pronounced the third syllable. Early years The son of a civil servant, Kekulé was born in Darmstadt, the capital of the Grand Duchy of Hesse. After graduating from secondary school (the Grand ...

Rudolf Clausius
Rudolf Julius Emanuel Clausius (; 2 January 1822 – 24 August 1888) was a German physicist and mathematician and is considered one of the central founding fathers of the science of thermodynamics. By his restatement of Sadi Carnot's principle known as the Carnot cycle, he gave the theory of heat a truer and sounder basis. His most important paper, "On the Moving Force of Heat", published in 1850, first stated the basic ideas of the second law of thermodynamics. In 1865 he introduced the concept of entropy. In 1870 he introduced the virial theorem, which applied to heat. Life Clausius was born in Köslin (now Koszalin, Poland) in the Province of Pomerania in Prussia. His father was a Protestant pastor and school inspector, and Rudolf studied in the school of his father. In 1838, he went to the Gymnasium in Stettin. Clausius graduated from the University of Berlin in 1844 where he had studied mathematics and physics since 1840 with, among others, Gustav Magnus, Peter Gustav Le ...
