Topic: Friedrich Wohler


  
 [No title]   (Site not responding. Last check: 2007-10-21)
Wohler received his medical degree in 1823 and on graduating from Heidelberg, on Gmelin's advice, he decided to give up practical medicine and take up the study of chemistry with the leading chemist of Europe, Jöns Jacob Berzelius*, in Stockholm.
Wohler's interest in cyanates also led, in 1828, to a scientific breakthrough, when he created urea, an organic substance, from ammonium cyanate, an inorganic compound.
Wohler was also fascinated by geological samples that were sent to him from all over the world by friends and ex-students.

 FRIEDRICH EBERT   (Site not responding. Last check: 2007-10-21)
Friedrich Ebert (February 4, 1871—February 28, 1925) was a German politician (SPD), who served as the 9th Chancellor of Germany and its first president during the Weimar period.
(Ironically, years later, Ebert's son, Friedrich 'Fritz' Ebert, became a Communist, served as Mayor of East Berlin, and briefly acted as East German interim head of state.) When the Constituent Assembly met in Weimar in February, 1919, Ebert was chosen to be the first president of the German Republic.
In spite of Ebert's support for the violent suppression of revolutionary uprisings, the German workers protected his government from the Kapp Putsch in 1920 by means of a nation-wide general strike.

Friedrich Wöhler (July 31, 1800 - September 23, 1882) was a German chemist, best-known for his synthesis of urea, but also the first to isolate several of the elements.
He was born in Eschersheim near Frankfurt am Main.

 Organics? Elementary....Wait! On Wohler and his times   (Site not responding. Last check: 2007-10-21)
Wohler went on to become professor of chemistry at Gottingen, where he became interested in substances that could release cyanide when heated.
Wohler excitedly wrote to Berzelius: "I must tell you that I can prepare urea without requiring a kidney of an animal, either man or dog." He somewhatremorsefully added that he had witnessed "the great tragedy of science, the slaying of a beautiful hypothesis by an ugly fact."
Although Wohler had shown that there was nothing mystical about organic materials, neither he nor his contemporaries could explain why they behaved differentlyfrom inorganic substances.

Born in 1800 at Escherheim, Wohler became interested in chemistry at a very early age, often neglecting the formal part of his education to collect rocks carry out experiments.
This discovery directly challenged the concept that the 'chemistry of life' was operating under different rules, and also suggested that it might be possible to study what was going on in a living organism using the traditional tools of the chemist.
The personalities of the two men could not have been more different, but their work together lead to some fundamental breakthroughs in chemistry, including the fact that the spatial configuration of atoms joined into molecules is an important property of compounds.

A pioneer in the field of organic chemistry, Wohler is famous for his synthesis
By this contribution he proved, contrary to scientific thinking of the time, that a product of the living processes of animals could be made in the laboratory from inorganic materials.
Wohler also conducted important research on uric acid and the oil of bitter almonds, in collaboration with the German chemist Baron Justus von Liebig, and isolated the chemical elements aluminium and beryllium (1827-1828).

Wohler's lectures for students at Göttingen were given four days a week beginning at 6 A.M. (There is no mention as to when they ended.) Wohler collaborated with Liebig on the chemistry of the benzoyl radical and he corresponded extensively with Berzelius.
In 1828, Wohler converted ammonium cyanate, an inorganic compound, into urea, an organic compound.
Nonetheless, Berzelius was impressed because the result was an example of isomerism, a topic of interest to him.

Then in 1825, a small lump of aluminium was produced by Hans Christian Oersted, a Danish chemist, whose work was further developed by Friederick Wohler of Germany.
Wohler's process was also improved by the French chemist Henri Sainte-Claire Deville who, with the assistance of France's Emperor Napoleon III, opened the world's first aluminium factory in 1859, at Glaciere near Paris.
Aluminium "as big as pin heads" was produced by Friedrich Wohler in Berlin.

In 1828, the German chemist, Friedrich Wohler, unintentionally converted tammonium cyanate, NH OCN, a purely inorganic substance, into urea, CO(NH which is and end product of animal metabolism.
Wohler's preparation of urea had another important consequence in that it furnished an example of two substances, urea and ammonium cyanate, which had the same chemical composition but very different properties.
As experimental techniques improved, it became clear that there were other examples of more than one substance having the same composition.

However, new findings particularly by Michel Eugene Chevreul (1786-1889) and Friedrich Wohler (1800-82) weakened the vital force theory and gradually it was abandoned.
However, it was Wohler who actually first synthesised an organic compound.
If Wohler’s success was not unam bigous, Adolph Wilhelm Hermann Kolbe (1818-84) synthesised acetic acid (an organic compound) directly from chemical elements.
