Stanley Miller’s Landmark Experiment on the Origin of Life

Stanley Miller’s Landmark Experiment on the Origin of Life

On March 7, 1930, American chemist Stanley Lloyd Miller was born. Miller made landmark experiments in the origin of life by demonstrating that a wide range of vital organic compounds can be synthesized by fairly simple chemical processes from inorganic substances. In 1952 he carried out the Miller–Urey experiment, which showed that complex organic molecules could be synthesized from inorganic precursors. The experiment was widely reported, and provided support for the idea…

Hans von Euler-Chelpin and the Alcoholic Fermentation of Sugar

Hans von Euler-Chelpin and the Alcoholic Fermentation of Sugar

On February 15, 1873, German-born Swedish biochemist Hans von Euler-Chelpin was born. Hans von Euler-Chelpin shared the 1929 Nobel Prize for Chemistry with Sir Arthur Harden for work on the role of enzymes in the alcoholic fermentation of sugar. Youth and Education Hans von Euler-Chelpin was the son of the later Bavarian Major General Rigas von Euler-Chelpin (1837-1923)and his wife Gabriele Furtner († 1931). He spent most of his childhood with his grandmother in…

Victor Moritz Goldschmidt and the Origins of Geochemistry

Victor Moritz Goldschmidt and the Origins of Geochemistry

On January 27, 1888, Swiss-Norwegian geochemist, mineralogist and petrologist Victor Moritz Goldschmidt was born. Goldschmidt is considered (together with Vladimir Vernadsky) to be the founder of modern geochemistry and crystal chemistry, as well as the developer of the Goldschmidt Classification of elements. “Every beginning is hard. At most stopping is sometimes even harder.” – Victor Moritz Goldschmidt, as quoted in [9] Victor Moritz Goldschmidt’s Early Years Goldschmidt was born in Zürich, Switzerland,…

Alexandre-Émile Béguyer de Chancourtois and the Order of the Chemical Elements

Alexandre-Émile Béguyer de Chancourtois and the Order of the Chemical Elements

On January 20, 1820, French geologist and mineralogist  Alexandre-Émile Béguyer de Chancourtois was born. De Chancourtois was the first to arrange the chemical elements in order of atomic weights in 1862. De Chancourtois only published his paper, but did not publish his actual graph with the irregular arrangement. Although his publication was significant, it was ignored by chemists as it was written in terms of geology. It was Dmitri Mendeleev’s table published in 1869…

Paul Müller and the Doubtful Qualities of DDT

Paul Müller and the Doubtful Qualities of DDT

On January 12, 1899, Swiss chemist and Nobel Laureate Paul Hermann Müller was born. Müller received the 1948 Nobel Prize in Physiology or Medicine for his 1939 discovery of insecticidal qualities and use of DDT in the control of vector diseases such as malaria and yellow fever. “We have discovered many preventives against tropical diseases, and often against the onslaught of insects of all kinds, from lice to mosquitoes and back again. The excellent…

Willard Frank Libby and the Radiocarbon Dating

Willard Frank Libby and the Radiocarbon Dating

On December 17, 1908, American physical chemist Willard Frank Libby was born. Libby is best known for his role in the 1949 development of radiocarbon dating, a process which revolutionized archaeology and palaeontology. For his contributions to the team that developed this process, Libby was awarded the Nobel Prize in Chemistry in 1960. Early Years Willard Frank Libby was born among two siblings in Grand Valley, Colorado, the son of farmers Ora…

Charles Coulson and the Molecular Orbital Theory

Charles Coulson and the Molecular Orbital Theory

On December 13, 1910, British applied mathematician and theoretical chemist Charles Coulson was born. Coulson was as a pioneer of the application of the quantum theory of valency to problems of molecular structure, dynamics and reactivity. He is known for the application of molecular orbital theory to chemical bonding, the electronic structures of molecules and the concept of partial valency, and developed many mathematical techniques for solving chemical and physical problems. Charles…

Lars Onsager and Irreversible Chemical Processes

Lars Onsager and Irreversible Chemical Processes

On November 27, 1903, Norwegian-born American physical chemist and theoretical physicist Lars Onsager was born. The development of a general theory of irreversible chemical processes gained him the 1968 Nobel Prize for Chemistry. These Onsager reciprocal relations have importance in a wide range of applications. Education Lars Onsager was born in Kristiania (today’s Oslo), Norway, to Erling Onsager, a Barrister of the Supreme Court of Norway, and Ingrid, née Kirkeby. After completing…

Charles-Adolphe Wurtz and the Atomic Theory

Charles-Adolphe Wurtz and the Atomic Theory

On November 26, 1817, Alsatian French chemist and educator Charles-Adolphe Wurtz was born. Wurtz is best remembered for his decades-long advocacy for the atomic theory and for ideas about the structures of chemical compounds, against the skeptical opinions of chemists such as Marcellin Berthelot and Etienne Henri Sainte-Claire Deville. He is well known by organic chemists for the Wurtz reaction, to form carbon-carbon bonds by reacting alkyl halides with sodium, and for…

Elmer McCollum and the Discovery of Vitamins

On November 15, 1967, American biochemist Elmer McCollum passed away. McCollum is known for his work on the influence of diet on health. Together with Marguerite Davis McCollum discovered the first vitamin, named A, in 1913. He also helped to discover vitamin B and vitamin D and worked out the effect of trace elements in the diet. Elmer McCollum – Youth hand Family Background Elmer McCollum was born on March 3, 1879,…
