He understated the importance of humus in plant nutrition and maintained that plants feed upon nitrogen compounds, carbon dioxide from air, and some minerals found in the soil. When he switched to a more soluble nitrogen compound, the health of the crops improved. April 1873 in München), war ein deutscher Chemiker und Universitätsprofessor in Gießen und München.

Liebig worked on the serious explosive silver fulminate, a salt of fulminic acid. Liebig and Wöhler worked together in order to unravel the complex nature of organic chemistry, which was just then becoming a major field of research. He expanded the scientific understanding of organic compounds, and championed the use of chemical fertilizers for agriculture. Liebig improved organic analysis with the Kaliapparat—a five-bulb device he introduced in 1831 that used a potassium hydroxide solution to remove the organic combustion product carbon dioxide. Much of his early research focused on the properties of mercury and silver fulminate, for which he determined empirical formulas. Liebig was born in Darmstadt, Germany, on May 12, 1803. As a young boy, Liebig first became an apprentice to an apothecary Gottfried Pirsch, and then attended the University of Bonn, studying under the influence of his father’s friend Karl Wilhelm Gottlob Kastner.
They also instituted the use of laboratory animals, and performed many experiments to determine metabolic byproducts of living systems. The process was used to improve mirrors in microscopes and later, in telescopes. We'll assume you're ok with this, but you can opt-out if you wish. Liebig’s major contributions to chemistry include the discovery that plants need nitrogen and carbon dioxide from the air, as well as minerals found in soil. The last period of his life was more devoted to conclusions based on earlier work than to original research. He belonged to a middle class family; his father was a pharmaceutical merchant and as a child, Liebig developed a keen interest in chemistry and conducted experiments freely in his father’s shop. In 1824, at the age of 21, Liebig was made a professor at the University of Giessen, based on the recommendation given by Kastner. Liebig revolutionized organic analysis using a five-bulb device called the “Kaliapparat”.
This concept is a qualitative version of the principles used to determine the application of fertilizer in modern agriculture.
Mai 1803 in Darmstadt; † 18. Justus von Liebig was a German chemist, who is widely credited as one of the founders of agricultural chemistry. Liebig believed that nitrogen must be supplied to plant roots in the form of ammonia. The University of Giessen today is officially named after him, "Justus-Liebig-Universität-Giessen". Justus Liebig, ab 1845 Justus Freiherr von Liebig (* 12.
Students flocked to the University of Giessen, where they could be sure to learn techniques of analytical chemistry and work in the budding field of organic chemistry.
After learning pharmacy for about six months, he acquired a degree in chemistry from the Prussian University of Bonn.
His teaching laboratory concentrated on the analysis of organic compounds. Working with Belgian engineer George Giebert, Liebig devised an efficient method of producing beef extract from carcasses. These chemicals were among the very first recognized examples of isomers, a term coined by Swedish chemist Jöns Jakob Berzelius. Germany was one of the most affected countries during the famine that ensued, and this experience is said to have shaped Liebig’s future interests to some extent. Justus von Liebig stirbt im April 1873 in München als hochangesehener Mann an einer Lungenentzündung. Born in Darmstadt, Germany on May 12, 1803, Justus von Liebig’s father was a chemical manufacturer whose shop had a small laboratory.
He established what became one of the first, and certainly the most influential, industrial-style research laboratories. Liebig often barked his findings, and caused much controversy in his time. 10 Great Scottish Inventors and Their Inventions, 10 Most Famous Black Inventors and Their Inventions. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Liebig also devised the Law of the Minimum. He applied his theories to raising crops on a small piece of land from 1845 to 1849, but because he was using an insoluble form of nitrogen that plants could not absorb, his efforts at first appeared ineffective.
Sugar, salicin [aspirin], and morphine will be artificially produced."
At the age of 16 he was apprenticed to the apothecary Gottfried Pirsch (1792-1870) in Heppenheim. He was the first person the invent a nitrogen-based fertilizer. Er entwickelte ein Herstellungsverfahren für Rindfleisch-Extraktesowie moderne Analyseverfahren und gründete die renom… Liebig was one of the true forefathers of modern agriculture. He made crucial contributions to the analysis of organic compounds, and, in his early years, also published several works on the use of inorganic fertilizers in several languages.

In the 1830s, Liebig began a research partnership with Friedrich Wöhler, who had already purified aluminum and synthesized the first organic compound, uric acid. Liebig 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. The more famous of these included August Wilhelm von Hofmann, Friedrich Kekule, Henri Victor Regnault, Alexander William Williamson and Emil Erlenmeyer. His work in the fields of plant and animal physiology is also very influential. You also have the option to opt-out of these cookies.

Justus von Liebig (May 12, 1803 – April 18, 1873) was a German chemist who made analytical chemistry accessible to a generation of European, British and American scientists by his innovative educational curriculum. Liebig was born in Darmstadt, the second son of Johann George Liebig and Maria Caroline Moeser. Using these fertilizers, nutrients were fed to plant roots in the form of ammonia. They also created derivatives from bitter almond oil, and established the composition of cyanic acid and numerous other organic compounds and their derivatives. Justus Freiherr von Liebig was a German chemist, who conducted crucial research in the areas of organic and inorganic chemistry, agricultural chemistry, physiology, and biochemistry.

Also at Erlangen, Liebig developed a friendship with the poet August von Platen (1796-1835), who wrote several sonnets dedicated to Liebig.

Liebig tended to dissociate the role of yeast metabolism from the production of acetic acid, while Pasteur was assured of its necessity. Said Liebig, "The doctrine that matter is not infinitely divisible, but, on the contrary, consists of atoms incapable of further division, alone furnishes us with a satisfactory explanation of these phenomena (of chemical composition)" (Charles, 1854). He worked in the private laboratory of Joseph Louis Gay-Lussac for about two years, during which time he made the acquaintance of European scientists of repute, including Alexander von Humboldt and Georges Cuvier. The concept of “isomerism” was later recognized by the Swedish chemist Jöns Jacob Berzelius. It must be viewed as not only probable but as certain that we shall produce them in our laboratories. The fields of organic chemistry, biochemistry and molecular biology can be traced to Liebig's researches and his ideas on the chemical basis of the life sciences. Liebig did not always come down on the right side of a debate, as is evidenced by his opposition to Pasteur's ideas.
