  Carl Wilhelm Scheele - Wikipedia, the free encyclopedia
Carl Wilhelm Scheele, (December 9, 1742 - May 21, 1786) a Swedish chemist, born in Stralsund, Pomerania, Germany (back then a Swedish province), was the discoverer of many chemical substances, most notably discovering oxygen before Joseph Priestley.
Scheele worked as a pharmacist in Stockholm, from 1770 to 1775 in Uppsala, and later in Köping.
Scheele also discovered other chemical elements such as barium (1774), chlorine (1774), manganese (1774), molybdenum (1778), and tungsten (1781), as well as several chemical compounds, including citric acid, glycerol, hydrogen cyanide (also known, in aqueous solution, as prussic acid), hydrogen fluoride, and hydrogen sulfide.

Carl Wilhelm Scheele nacque a Straslund, in Pomerania, il 9 dicembre 1742; morì a Köping, in Svezia, il 21 maggio 1786.
Scheele inoltre scoprì il tungsteno, il molibdeno, l'azoto, il cloro (per azione dell'acido cloridrico sul biossido di manganese e la manganese.
Riuscì a preparare tanti nuovi composti, tra cui il solfuro di idrogeno, l'arsenito di rame (detto verde di Scheele) e l'acido tartarico.

Carl Wilhelm Scheele of Karl Wilhelm Scheele (9 december 1742 - 21 mei 1786), geboren in Stralsund, Duitsland, was een Zweedse chemicus en ontdekker van veel scheikundige elementen.
Nadat Scheele als apotheker werkzaam was in Stockholm verhuisde hij in 1770 naar Uppsala en in 1775 naar Köping.
Een andere ontdekking van Scheele is het pigment koperarseniet, dat gebruikt werd als kleurstof in voedsel en bekend werd als Scheele's groen.

 Scheele, Carl Wilhelm
At the age of fourteen Scheele was apprenticed to an apothecary in Gothenburg and later in Malmö where he started to conduct chemical experiments.
Scheele published his studies mostly in the proceedings of the Royal Academy of Sciences in Stockholm which called the self-made scientist to be its full member.
Due to the significant achievements in inorganic chemistry, Scheele's accomplishments in organic chemistry are often overlooked.

To the southwest is the flooded Letronne crater remnant.
Just to the west of Scheele crater are several low ridges projecting above the surface of the lunar mare.

 Carl Scheele
Carl Scheele was born December 9, 1742, one of eleven children.
At age 14, Scheele became an apprentice apothecary of the firm Martin Anders Bauch in Gothenburg.
Scheele was isolated from much scientific literature although he did communicate with Lavoisier who sent him a copy of his early book.

Scheele's treatise contains accounts of the numerous chemical experiments Scheele performed to demonstrate that common air, when freed from "aerial acid" (carbon dioxide) and water vapor, consists of two gases: "fire air" (oxygen) which supports combustion, and "foul air" (nitrogen), which does not.
Like Priestley, Scheele was an adherent of the phlogiston theory, and he accounted for oxygen's combustibility by describing it as peculiarly attractive to phlogiston.
Scheele made numerous other important contributions to chemistry, including the discoveries of chlorine, manganese, and a number of acids.

 CARL WILHELM SCHEELE
Scheele arbeitete als Apotheker in Stockholm, von 1770 bis 1775 in Uppsala, danach in Köping.
Seine Studien führten im Zeitraum von 1772 bis 1773 zur Entdeckung von Sauerstoff und Stickstoff, die Ergebnisse publizierte er aber erst 1777 in seinem einzigem Buch „Chemische Abhandlung von der Luft und dem Feuer', wodurch er etwas von dem Ruhm an Joseph Priestley verlor, der unabhängig von ihm den Sauerstoff 1774 entdeckte.
Scheele entdeckte außerdem die Elemente Chlor (1774), Mangan (1774), Molybdän (1778), Wolfram (1781) und Barium.

 San Diego Playbill - Local Reviews
Carl Scheele (Jeff Anthony Miller) and his companion, confidant, and comforter, Sara Pohl (Jennifer Austin), both play the part of the victimized underdogs very well, certainly gaining the sympathy votes from the audience.
Scheele's failed attempt to publish his findings and the "lost" letter sent to Lavoisier have resulted in his losing distinction for his discovery.
With Scheele being the first to discover oxygen, and Lavoisier being the first to demonstrate its value and stealing all the credit, the fact that Priestly published the discovery in between Scheele's and Lavoisier's work seems a rather pale accomplishment in comparison.

Scheele holds a record for discovering seven natural elements (N, O, Cl, Mn, Mo, Ba, W), but he had to share credit in every case because his results were not published quickly enough to obtain undisputed priority.
He used the means available, including taste, and it is thought that poisoning by heavy metals (he also discovered hydrogen cyanide) may have contributed to his health problems and to his death at the age of 44.
One of his creations was the green pigment copper arsenite, which as "Scheele's green" became a popular coloring for confections, until it was discovered half a century later to be poisonous.

Obwohl neben Scheele auch der englische Geistliche Joseph Priestley (1733—1804) als Entdecker des Sauerstoffs genannt werden muss, gilt heute als gesichert, dass Scheele dieses Gas bereits vor Priestley, nämlich zwischen Juni 1771 und Oktober 1772, entdeckte.
Obwohl Scheele in seiner Schrift ›Chemische Abhandlung von der Luft und dem Feuer‹ ausführlich über die Eigenschaften des Sauerstoffes berichtete, blieb er selbst bis zu seinem Tode der Phlogistontheorie verhaftet.
Mit Recht gilt Scheele noch heute in der Pharmazie- und Chemiegeschichtsschreibung als einer der bedeutendsten Vertreter und als einer der glänzendsten Experimentatoren.

Scheeles sätt att begagna böckerna lät honom i stället snart bli »för hög» för dem.
Och när Scheele, efter åtta år hos Bauch, fick kondition i Malmö på apoteket »Fläkta örn», 1765, var han antagligen redan mästare i analysen.

It is a tempestuous period: the wealthy Lavoisier was guillotined during the Reign of Terror in 1794.
The problem is this-we now know that Scheele first discovered oxygen around 1771-2; Priestley discovered it totally independently in 1774, disclosed his discovery to Lavoisier during a visit to Paris in that year and published first.
