Liebig was born in Darmstadt into a middle class family. Darmstadt is a city in the Bundesland From childhood he was fascinated by chemistry and even 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. A grammar school is one of several different types of School in the history of education in the United Kingdom and other English-speaking countries An explosive material is a material that either is chemically or otherwise Energetically unstable or produces a sudden expansion of the material usually accompanied Drysalters were dealers in a range of chemical products including glue varnish dye and colourings [This tale is probably apocryphal--there is no historical evidence that it occurred. ] He was apprenticed to the apothecary Gottfried Pirsch (1792-1870) in Heppenheim. Heppenheim (Bergstraße is the seat of Bergstraße district in Hesse, Germany, lying on the Bergstraße on the edge of the Odenwald
Liebig attended the University of Bonn, studying under Karl Wilhelm Gottlob Kastner, a business associate of his father. The University of Bonn ( German: Rheinische Friedrich-Wilhelms-Universität Bonn) is a public research university located in Bonn, Germany Karl Wilhelm Gottlob Kastner (1783 - 1857 was a German Chemist and natural scientist When Kastner moved to the University of Erlangen, Liebig followed him and later took his doctorate from Erlangen. History The university was founded in 1742 in Bayreuth by Frederick Margrave of Bayreuth, and moved to Erlangen in 1743 Liebig did not receive the doctorate until well after he had left Erlangen, and the circumstances are clouded by a possible scandal [see Munday (1990)]. Also at Erlangen, Liebig fell in love with the poet August Graf von Platen (1796-1835)[1] who wrote several sonnets dedicated to Liebig. He left Erlangen in March 1822, in part because of his involvement with the radical Korps Rhenania (a nationalist student organization) but also because of his hopes for more advanced chemical studies.
In autumn 1822 Liebig went to study in Paris on a grant obtained for him by Kastner from the Hessian government. Paris (ˈpærɨs in English; in French) is the Capital of France and the country's largest city Hesse (Hessen is a state of Germany with an area He worked in the private laboratory of Joseph Louis Gay-Lussac, and was also befriended by Alexander von Humboldt and Georges Cuvier (1769-1832). A laboratory (informally lab) is a facility that provides controlled conditions in which scientific Research, Experiments and Joseph Louis Gay-Lussac (also Louis Joseph Gay-Lussac, December 6, 1778 – May 9, 1850) was a French chemist (September 14 1769 &ndash May 6 1859 was a German naturalist and explorer, and the younger brother of the Prussian minister philosopher and linguist Baron Georges Léopold Chrétien Frédéric Dagobert Cuvier ( August 23 1769 &ndash May 13, 1832) was a French naturalist
After leaving Paris, Liebig returned to Darmstadt and married Henriette Moldenhauer, the daughter of a state official. This ended Liebig's relationship with Platen.
In 1824 at the age of 21 and with Humboldt's recommendation, Liebig became a professor at the University of Giessen. The meaning of the word professor ( Latin: professor, person who professes to be an expert in some art or science teacher of highest rank) varies The University of Gießen (German Universität Gießen) is officially called Justus Liebig-Universität Gießen after its most famous member He established the world's first major school of chemistry there. He received an appointment from the King of Bavaria to the University of Munich in 1852, where he remained until his death in 1873 in Munich. The Ludwig Maximilian University of Munich (Ludwig-Maximilians-Universität München also known as LMU, is a University in Munich and with more Munich (München; Minga is the capital city of Bavaria, Germany. He became Freiherr (baron) in 1845.
He founded and edited from 1832 the journal Annalen der Chemie, which became the leading German-language journal of Chemistry. Official title Annalen der Chemie, 1832–1839 Annalen der Chemie und Pharmacie, 1840–1872 (ISSN 0075-4617 CODEN JLACBF The volumes from his lifetime are often referenced just as Liebigs Annalen; and following his death the title was officially changed to Justus Liebigs Annalen der Chemie.
Liebig improved organic analysis with the Kaliapparat-- a five-bulb device that used a potassium hydroxide solution to remove the organic combustion product carbon dioxide. He downplayed the role of humus in plant nutrition and discovered that plants feed on nitrogen compounds and carbon dioxide derived from the air, as well as on minerals in the soil. Humus (Origin 1790–1800 Latin: earth ground) is the organic material in Soil lending it a dark brown or black colouration Nutrition (also called nourishment or aliment) is the provision to cells and Organisms of the materials necessary (in the form of food to support Nitrogen (ˈnaɪtɹəʤɪn is a Chemical element that has the symbol N and Atomic number 7 and Atomic weight 14 Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Soil, often typeset as SOiL, is a four piece rock band from Chicago Illinois United States founded by Shaun Glass Tom Schofield Tim King and Adam Zadel One of his most recognized and far-reaching accomplishments was the invention of nitrogen-based fertilizer. Fertilizers ( also spelt fertiliser are chemical compounds given to Plants to promote growth they are usually applied either through the soil for uptake by plant Liebig believed that nitrogen must be supplied to plant roots in the form of ammonia. Though a practical and commercial failure, his invention of fertilizer recognized the possibility of substituting chemical fertilizers for natural (animal dung, etc. ) ones. He also formulated the Law of the Minimum, stating that a plant's development is limited by the one essential mineral that is in the relatively shortest supply, visualized as "Liebig's barrel". Liebig's Law of the Minimum, often simply called Liebig's Law or the Law of the Minimum, is a principle developed in Agricultural science by Carl Sprengel This concept is a qualitative version of the principles used to determine the application of fertilizer in modern agriculture.
He was also one of the first chemists to organize a laboratory as we know it today. His novel method of organic analysis made it possible for him to direct the analytical work of many graduate students. The vapor condensation device he popularized for his research is still known as a Liebig condenser, although it was in common use long before Liebig's research began. In a Laboratory, a condenser is a piece of Laboratory glassware used to cool hot vapors or liquids Liebig's students were from many of the German states as well as Britain and the United States, and they helped create an international reputation for their Doktorvater.
In 1835 he invented a process for silvering that greatly improved the utility of mirrors. Silvering is the chemical process of coating Glass with a reflective substance A mirror is an object with a surface that has good Specular reflection; that is it is smooth enough to form an Image.
Liebig's work on applying chemistry to plant and animal physiology was especially influential. At a time when many chemists such as Jöns Jakob Berzelius insisted on a hard and fast separation between the organic and inorganic, Liebig argued that ". Friherre Jöns Jacob Berzelius (20 August 1779 &ndash 7 August 1848 was a Swedish chemist . . the production of all organic substances no longer belongs just to the organism. It must be viewed as not only probable but as certain that we shall produce them in our laboratories. Sugar, salicin [aspirin], and morphine will be artificially produced. " [Liebig and Woehler (1838)]
Liebig's arguments against any chemical distinction between living (physiological) and dead chemical processes proved a great inspiration to several of his students and others who were interested in materialism. Though Liebig distanced himself from the direct political implications of materialism, he tacitly supported the work of Karl Vogt (1817-1895), Jacob Moleschott (1822-1893), and Ludwig Buechner (1824-1899).
Liebig played a more direct role in reforming politics in the German states through his promotion of science-based agriculture and the publication of John Stuart Mill's Logic. John Stuart Mill (20 May 1806 &ndash 8 May 1873 British Philosopher, political economist, civil servant and Member of Parliament, was an influential Through Liebig's close friendship with the Vieweg family publishing house, he arranged for his former student Jacob Schiel (1813-1889) to translate Mill's important work for German publication. Liebig liked Mill's Logic in part because it promoted science as a means to social and political progress, but also because Mill featured several examples of Liebig's research as an ideal for the scientific method. Liebig is also credited with the notion that "searing meat seals in the juices. Searing (or pan searing) is a technique used in Grilling, Roasting, Braising, Sautéing, etc "[2] This idea, still widely believed, is not true.
Working with Belgian engineer George Giebert, Liebig devised an efficient method of producing beef extract from carcasses. The Kingdom of Belgium is a Country in northwest Europe. It is a founding member of the European Union and hosts its headquarters as well as those An engineer is a person professionally engaged in a field of Engineering. In 1865, they founded the Liebig Extract of Meat Company, marketing the extract as a cheap, nutritious alternative to real meat. The Liebig Extract of Meat Company (Lemco was the originator of Liebig and Oxo Meat extracts and later Oxo beef Stock cubes It was named after Baron In modern English usage meat most often refers to Animal tissue used as food mostly Skeletal muscle and associated Fat, but it may also refer Some years after Liebig's death, in 1899, the product was trademarked "Oxo". Oxo is a brand of various food products consisting of stock cubes, herbs and spices dried gravy and Yeast extract.
After World War II, the University of Giessen was officially renamed after him, "Justus-Liebig-Universität Giessen". World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including The University of Gießen (German Universität Gießen) is officially called Justus Liebig-Universität Gießen after its most famous member In 1953 the West German post office issued a stamp in his honor. West Germany ( Inf German: Westdeutschland or West-Deutschland) was the common English name for the Federal Republic of Germany ( The Deutsche Bundespost ( German federal Post office) was created in 1947 as a successor to the Reichspost (German imperial post office [3]
