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. 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…
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. 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…
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,…
Elmer McCollum and the Vitamins

Elmer McCollum and the 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. In 1903, Elmer McCollum graduated from the University of Kansas. He secured a…
Carl Djerassi and the Oral Contraceptive Pill

Carl Djerassi and the Oral Contraceptive Pill

On October 29, 1923, Austrian-born Bulgarian-American chemist, novelist, and playwright Carl Djerassi was born. Djerassi is best known for his contribution to the development of oral contraceptive pills. Furthermore, he is noted for establishing physical methods for determining organic molecular structure and his contributions to synthetic organic chemistry, his effectiveness in translating scientific knowledge into technological practice, and his efforts to promote international scientific cooperation. Carl Djerassi was born in…
Nathaniel Wyeth and the PET Bottle

Nathaniel Wyeth and the PET Bottle

On October 24, 1911, American mechanical engineer and inventor Nathaniel C. Wyeth was born. Wyeth is best known for creating polyethylene terephthalate that could withstand the pressure of carbonated liquids. Made of recyclable PET plastic, lighter than glass and virtually unbreakable, Wyeth’s invention is used widely today for both carbonated and non-carbonated drinks. Nathaniel Wyeth was the brother of the painters Andrew Wyeth and Henriette Wyeth Hurd as well as…
Harold Kroto and the Fullerenes

Harold Kroto and the Fullerenes

On October 7, 1939, English chemist and Nobel Laureate Sir Harold Walter Kroto was born. Kroto shared the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley [6] for their discovery of fullerenes, i.e. molecules of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes, which have been the subject of intense research, both for their unique chemistry and for their technological applications,…
Francis William Aston and the Mass Spectrograph

Francis William Aston and the Mass Spectrograph

On September 1, 1877, English chemist, physicist, and Nobel Laureate Francis William Aston was born. Aston won the 1922 Nobel Prize in Chemistry for his discovery, by means of his mass spectrograph, of isotopes, in a large number of non-radioactive elements, and for his enunciation of the whole number rule. Francis William Aston attended Harborne Vicarage School and Malvern College. He entered Mason College, Birmingham in 1894 and studied chemistry…
Christian Friedrich Schönbein – Ozone and Explosives

Christian Friedrich Schönbein – Ozone and Explosives

On August 29, 1868, German-Swiss chemist Christian Friedrich Schönbein passed away. Schönbein is best known for inventing the fuel cell (1838) at the same time as William Robert Grove and his discoveries of guncotton and ozone, of which he also coined its name. Christian Friedrich Schönbein was apprenticed to a chemical and pharmaceutical firm at Böblingen when he was 13 years old. Due to his hard work and the sufficient…
