Carl Remigius Fresenius and the Analytical Chemistry

Carl Remigius Fresenius and the Analytical Chemistry

On December 28, 1818, German chemist Carl Remigius Fresenius was born. Fresenius is known for his studies in analytical chemistry. He devised a method for systematic identification and separation of individual metal and non-metal ions, selecting the most suitable reactions from the many that were known. Carl Remigius Fresenius was first occupied at a pharmacy. In 1840, he entered Bonn University. One year later Fresenius moved to Gießen where he acted…
Jaroslav Heyrovský and the Polarography

Jaroslav Heyrovský and the Polarography

On December 20, 1890, Czech chemist and inventor Jaroslav Heyrovský was born. Jaroslav Heyrovský received the 1959 Nobel Prize in Chemistry “for his discovery and development of the polarographic methods of analysis” (1922), which is one of the most versatile analytical techniques. It applies the principle that in electrolysis the ions are discharged at an electrode and, if the electrode is small, the current may be limited by the rate of…
Richard Kuhn and his Work on Carotinoids and Vitamins

Richard Kuhn and his Work on Carotinoids and Vitamins

On December 3, 1900, Austrian-German biochemist Richard Johann Kuhn was born. Kuhn was awarded the Nobel Prize in Chemistry in 1938 “for his work on carotenoids and vitamins“. Kuhn is also credited with the discovery of the deadly nerve agent Soman in 1944. Before entering the University of Vienna in 1918, Richard Kuhn attended the same classes as the later Nobel Prize winner Wolfgang Pauli. In 1919, Kuhn moved to the…
Martin Heinrich Klaproth and the Analytical Chemistry

Martin Heinrich Klaproth and the Analytical Chemistry

On December 1, 1743, German chemist Martin Heinrich Klaproth was born. Klaproth became well known a founder of analytical chemistry discovered uranium (1789), zirconium (1789), cerium (1803), and contributed to the identification of others. Although he did not isolate them as pure metal samples, he was able to recognize them as new elements. Martin Heinrich Klaproth worked at the council pharmacy in Quedlinburg, and later became assistant in various pharmacies…
Henry Taube and the Mechanisms of Electron-transfer Reactions

Henry Taube and the Mechanisms of Electron-transfer Reactions

On November 30, 1915, Canadian-born American chemist Henry Taube was born. Taube has been awarded the 1983 Nobel Prize in Chemistry for his extensive research into the properties and reactions of dissolved inorganic substances, particularly oxidation-reduction processes involving the ions of metallic elements. Metals often form complexes, in which other atoms cluster around the metal atom, transferring and sharing electrons among themselves to bind together. Taube discovered that during a…
Karl Ziegler’s Work on Polymers

Karl Ziegler’s Work on Polymers

On November 26, 1898, German chemist and Nobel laureate Karl Ziegler was born. Ziegler won the Nobel Prize in Chemistry in 1963, with Giulio Natta, for work on polymers. He is also known for his work involving free-radicals, many-membered rings, and organometallic compounds, as well as the development of Ziegler–Natta catalyst. Karl Ziegler was born in Helsa near Kassel, Germany and was the second son of Karl Ziegler, a Lutheran…
Russian Polymath Mikhail Lomonosow

Russian Polymath Mikhail Lomonosow

On November 19, 1711, Russian polymath, scientist and writer Mikhail Lomonosov was born. Lomonosov made important contributions to literature, education, and science. Among his discoveries were the atmosphere of Venus and the Law of Mass Conservation in chemical reactions. His spheres of science were natural science, chemistry, physics, mineralogy, history, art, philology, optical devices and others. Lomonosov was also a poet and influenced the formation of the modern Russian literary language.…
George B. Kistiakowsky and the Manhattan Project

George B. Kistiakowsky and the Manhattan Project

On November 18, 1900, Ukrainian-American physical chemist Kistiakowsky was born. Kistiakowsky worked on developing the first atomic bomb but later advocated banning nuclear weapons. In the Manhattan project, he was in charge of X Division, which was responsible for the development of the explosive lenses necessary for an implosion-type nuclear weapon. In his youth, George Bogdanovich Kistiakowsky joined the anti-Communist White Army and escaped from Russia in a french ship.…
Auguste Laurent and Organic Chemistry

Auguste Laurent and Organic Chemistry

On November 14, 1807, French chemist Auguste Laurent was born. Laurent developed organic chemistry as a distinct science. For a while, he assisted Jean Dumas, and extended his work, understanding organic compounds as derivatives of hydrocarbon molecules. He devised a systematic nomenclature for organic chemistry based on structural grouping of atoms within molecules to determine how the molecules combine in organic reactions. Auguste Laurent was born in the district of…
John A. Pople and Computational Methods in Quantum Chemistry

John A. Pople and Computational Methods in Quantum Chemistry

On October 31, 1925, British theoretical chemist and Nobel laureate Sir John Anthony Pople was born. Pople was awarded the Nobel Prize in Chemistry with Walter Kohn in 1998 for his work on computational methodology to study the quantum mechanics of molecules, their properties and how they act together in chemical reactions. John A. Pople was born in Burnham-on-Sea, Somerset, UK, to his father Herbert Keith Pople, who, when he…
