 Baron Justus Von Liebig - LoveToKnow 1911
LIEBIG, JUSTUS VON, Baron (1803-1873), German chemist, was born at Darmstadt, according to his baptismal certificate, on the 12th of May 1803 (4th of May, according to his mother).
He remained at Giessen for twenty-eight years, until in 1852 he accepted the invitation of the Bavarian government to the ordinary chair of chemistry at Munich university, and this office he held, although he was offered the chair at Berlin in 1865, until his death, which occurred at Munich on the 10th of April 1873.
Apart from Liebig's labours for the improvement of chemical teaching, the influence of his experimental researches and of his contributions to chemical thought was felt in every branch of the science.

Freiherr Justus von Liebig (May 12, 1803 in Darmstadt, Germany – April 18, 1873 in Munich, Germany) was a German chemist who made major contributions to agricultural and biological chemistry, and worked on the organization of organic chemistry.
As a professor, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of all time.
Liebig was expelled from his grammar school for detonating an explosive device he had made at home from chemicals obtained from his father's drysaltery business.

Justus Baron von Liebig (1803-1873), a founder of agricultural chemistry, in his essay "Chemistry in Its Application to Agriculture and Physiology," refuted the theory that only organic material (specifically, humus) nourished plants.
Liebig used quantitative analysis in the study of biological systems and demonstrated what had been deemed "vital activity" could be fully understood in physicochemical terminology.
Opposition to the use of synthetic fertilizer beginning in the 1920s was a continuation of the vitalist dissent from Woehler and Liebig and from the foundation of organic chemistry a century earlier.

In the 19th century, leading physiologists including Marie François Xavier Bichat (1771-1802), Johannes Müller (1801-58) and Justus, Baron von Liebig (1803-73) believed that processes within living organisms were unique and could not be duplicated in the laboratory.
Liebig accused Wöhler of being an incompetent analyst.
Whenever possible, Liebig would explain chemical reactions occurring in agricultural chemistry or in animal chemistry, in terms of the behaviour of molecules, without resort to any ‘vital’ forces.

Von Liebig estudió en la Universidad de Bonn con Karl Wilhelm Gottlob Kastner, a quien siguió a la Universidad de Erlangen para doctorarse en 1822.
Liebig mejoró el análisis orgánico y descubrió que las plantas se alimentan gracias al nitrógeno y al dióxido de carbono del aire (con la contribución de microbios que realizan las conversiones a compuestos del nitrógeno) y de los minerales del suelo.

When concentrated sulfuric acid is heated, it behaves also as an oxidizing agent, capable, for example, of dissolving such relatively unreactive metals as copper, mercury, and lead to produce metal sulfate, sulfur dioxide, and water.
During the 19th century, the German chemist Baron Justus von Liebig discovered that sulfuric acid, when added to the soil, increased the amount of soil phosphorus available to plants.
This discovery gave rise to an increase in the commercial production of sulfuric acid and led to improved methods of manufacture.
