  Justus von Liebig and Friedrich Wöhler
Liebig learned to perform chemical operations as a child in his father's small laboratory, which was maintained to support the family drug and painting-materials business in Darmstadt, Germany.
After Liebig finished his university studies in Germany, his ambitions led him to work in Paris with Joseph Louis Gay-Lussac, who was in the forefront of chemical research at that time.
Liebig was soon appointed to the University of Giessen, where he immediately set about providing the kind of opportunities he had enjoyed in Gay-Lussac's laboratory, but for many more students at a time.

  Justus von Liebig - Wikipedia, the free encyclopedia
Freiherr Justus von Liebig (May 12, 1803 in Darmstadt, Germany - April 18, 1873 in Munich, Germany) was a German chemist.
Liebig went to the University of Bonn, to study with Karl Wilhelm Gottlob Kastner.
Liebig improved organic analysis, and discovered that plants feed on the nitrogen (actually microbes do the conversions to nitrogen compounds) and carbon dioxide in the air, as well as on minerals in the soil.

 Chrono-Biographical Sketch: Justus von Liebig
Liebig was one of the nineteenth century's front-rank chemists, both for his leading work in developing the fields of organic chemistry and agricultural chemistry, and for his efforts on behalf of the professionalization of the science.
First, Liebig helped debunk the commonly held notion that plant fertility was due only to organic substances, showing that minerals, water, and atmospheric gases were of primary import, and thus paving the way for all manner of physiological ecology-related environmental studies.
Liebig also introduced the "law of the minimum," the idea that agricultural crop yield is directly related to the least available critical nutrient, whatever that may be in a particular instance.

In a study of animal chemistry, Liebig treated physiologic processes as chemical reactions and inferred the transformations from the chemical properties of the elements and compounds in laboratory reactions.
Liebig generalized that all organic nitrogenous constituents of the body are derived from plant protein and demonstrated how the application of quantitative methods of organic chemistry can be applied to the investigation of the animal organism.
Liebig's theories were attractive, but his method of converting one substance to another by moving atoms around on paper was speculative because of the lack of knowledge as to how the elements were arranged.

 Sportscience History Makers - Liebig
Liebig restudied protein compounds (alkaloids previously discovered by the chemist Mulder), and concluded that muscular exertion by horses or humans required mainly protein, not carbohydrate and fat.
Liebig argued that consuming his extract and meat would help the body perform extra "work" to convert plant material into useful substances (Holmes, 1974; Shenstone, 1895).
Liebig, a giant in his field at the time, fell prey to a common dilemma: how to capitalize on commercial efforts while maintaining academic respectability.

 Justus Liebig
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 loth of April 1873.
Apart from Liebig's labors 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.
His contributions to inorganic chemistry were numerous, including investigations on the compounds of antimony, aluminium, silicon, etc., on the separation of nickel and cobalt, and on the analysis of mineral waters, but they are outweighed in importance by his work on organic substances.

Liebig played a leading role in the development of large scientific laboratories and agricultural experimental stations.
Liebig's Die Organische Chemie in ihre Anwendung auf Agricultur und Physiologie (organic chemistry in its applications to agriculture and physiology) supported the view that the source of carbon assimilated into plant substances is atmospheric carbon dioxide, and that the source of hydrogen and oxygen is water.
This generalization became known as Liebig's "Law of the Minimum" and it remains today a central concept in agriculture.
