Fieldurea

Friedrich Wöhler (July 31, 1800 - September 23, 1882) was a German urea, but also the first to isolate several of the elements.

Early days

He was born in Eschersheim, nowadays a district of Frankfurt am Main. In 1823 Wöhler finished his study of medicine in Heidelberg at the laboratory of Leopold Gmelin, who arranged for him to work under Jöns Jakob Berzelius in Stockholm. He taught chemistry from 1825 to 1831 at the Polytechnic School in Berlin; then till 1836 he was stationed at the Higher Polytechnic School at Kassel, and then he became Ordinary Professor of Chemistry in the University of Göttingen, where he remained till his death.

Contributions to chemistry

Wöhler is regarded as a pioneer in urea. Berzelius, in his report to the Royal Swedish Academy of Sciences, called it the most important of all researches in physics, chemistry, and mineralogy published in that year. The results were quite unexpected, and furnished additional evidence in favour of isomerism.

Major works, discoveries and research

  Wöhler was also a co-discoverer of calcium carbide, among others. In 1834, Wöhler and Liebig published an investigation of the oil of bitter almonds. They proved by their experiments that a group of chemical compounds. Thus the foundation was laid of the doctrine of compound radicals, a doctrine which had a profound influence on the development of chemistry.

Since the discovery of silicon) can be obtained in crystals, and that some meteoric stones contain organic matter. He analyzed a number of meteorites, and for many years wrote the digest on the literature of meteorites in the Jahresbericht der Chemie; he possessed the best private collection of meteoric stones and irons existing. Wöhler and Sainte Claire Deville discovered the crystalline form of boron, and Wöhler and Buff the hydrogen compounds of silicon (the silanes) and a lower oxide of the same element.

Final days and legacy

Wöhler's discoveries had great influence on the theory of chemistry. The journals of every year from 1820 to 1881 contain contributions from him. It was remarked that "for two or three of his researches he deserves the highest honor a scientific man can obtain, but the sum of his work is absolutely overwhelming. Had he never lived, the aspect of chemistry would be very different from that it is now."[citation needed]

While sojourning at Cassel, Wöhler made, among other chemical discoveries, one for obtaining the metal nickel in a state of purity, and with two friends he founded a factory there for the preparation of the metal.

Wöhler had several students who became notable chemists. Among them were Heinrich Limpricht, Vojtěch Šafařík.
