Marc Delafontaine
Marc Delafontaine (March 31, 1837/1838, Céligny, Switzerland–1911) was a Switzerland, Swiss chemist and spectroscopist who was involved in discovering and investigating some of the rare earth elements. Career Delafontaine studied with Jean Charles Galissard de Marignac at the University of Geneva. He also worked at the University of Geneva. Delafontaine moved to the United States of America, arriving in New York in 1870, and later becoming a naturalized citizen. He taught in Chicago, Illinois at city high schools, and at a women's college. He also worked as an analytical chemist with the Chicago Police Department. Research Holmium In 1878, along with Jacques-Louis Soret, Delafontaine first observed holmium spectroscopically. In 1879, Per Teodor Cleve chemically separated it from thulium and erbium. All three men are given credit for the element's discovery. Yttrium, terbium and erbium In 1843, Carl Gustaf Mosander discovered terbium and erbium as components of yttria. H ...

Carl Gustaf Mosander
Carl Gustaf Mosander (10 September 1797 – 15 October 1858) was a Swedish chemist. He discovered the rare earth elements lanthanum, erbium and terbium. Early life and education Born in Kalmar, Mosander attended school there until he moved to Stockholm with his mother in 1809. In Stockholm, he became an apprentice at the ''Ugglan'' pharmacy. He took his pharmacy examination in 1817, but had an interest in medicine and joined the Karolinska Institute in 1820. He passed his medical examination in 1825.

19th-century Swiss 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 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 and confirm cer ...

Discoverers Of Chemical Elements
Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday experiences. Some discoveries represent a radical breakthrough in knowledge or technology. Others are based on earlier discoveries, collaborations or ideas. In such cases, the process of discovery requires at least the awareness that an existing concept or method could be modified or transformed. New discoveries are made using various senses, and are usually added to pre-existing knowledge. Questioning plays a key role in discovery; discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. Science Within scientific discip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1830s Births
Year 183 ( CLXXXIII) was a common year starting on Tuesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Aurelius and Victorinus (or, less frequently, year 936 ''Ab urbe condita'').

Upton, New York
Upton is a hamlet and census-designated place (CDP) located on Eastern Long Island in the town of Brookhaven in Suffolk County, New York, United States. It is the home of the Brookhaven National Laboratory and a National Weather Service (NWS) Weather Forecast Office (WFO) on the grounds of the national lab. This NWS WFO is code "OKX", and serves the New York metropolitan area. The town is so named because it was the site of the U.S. Army's Camp Upton, which was active from 1917 until 1920, and again from 1940 until 1946. During World War II, the camp was rebuilt primarily as an induction center for draftees. The Army was later to use the site as a convalescent and rehabilitation hospital for returning wounded. The 32 megawatt (MW) Long Island Solar Farm (LISF), located in Upton, is the largest photovoltaic array in the eastern United States. The LISF is made up of 164,312 solar panels which provide enough electricity for roughly 4,500 households. The project will cause t ...

Nils Johan Berlin
Nils Johan Berlin (Nils Johannes Berlin) (18 February 1812 – 27 December 1891) was a Sweden, Swedish chemist and physician, who held various professorships at the University of Lund from 1843 to 1864. Berlin was the first chemist who took the initiative to write a textbook on elementary science, the purpose being to provide basic science education for the Public, general public. His chemistry research emphasized the study of minerals, especially the newly-discovered rare earths, having devised means of separating yttrium and erbium. The mineral berlinite (a type of aluminium phosphate) is named after him. Berlin became a member of the Royal Swedish Academy of Sciences in 1844. Education Berlin graduated from the University of Uppsala with a doctor of philosophy in 1833, having studied under the tutelage of Jöns Jacob Berzelius.
