George Kistiakowsky – From the Manhattan Project to a Nuclear Weapons Ban

George Kistiakowsky – From the Manhattan Project to a Nuclear Weapons Ban

On November 18, 1900, Ukrainian-American physical chemist George 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. Education and Academic Career George Bogdanovich Kistiakowsky went to the Russian Revolution in 1917 in Kiev and Moscow in private schools. However,…

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. Youth and Education Auguste Laurent was born in the district…

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. “Sometimes one can improve the theories in the sense of discovering a quicker, more efficient way of doing a given…

Cyril Ponnamperuma and the Origins of Life

Cyril Ponnamperuma and the Origins of Life

On October 16, 1923, Ceylonese-American chemist and exobiologist Cyril Ponnamperuma was born. Cyril Ponnamperuma was a leading authority on the chemical origins of life. He built on the work of Miller and Clayton Urey studying chemical reactions in “primordial soup” experiments. Ponnamperuma focused on producing compounds related to the nucleic acids and offered a convincing theory about series of chemical reactions that gave rise to precursors of life on earth. Education Cyril Andrew…

Henry Louis Le Châtelier and the Le Châtelier Principle

Henry Louis Le Châtelier and the Le Châtelier Principle

On October 8, 1850, French chemist Henry Louis Le Chatelier was born. Le Châtelier is most famous for devising Le Chatelier’s principle, with the help of his partner Jasper Rossi, used by chemists to predict the effect a changing condition has on a system in chemical equilibrium. Youth and Education Le Châtelier was born in Paris, France, the first of six children [1] of French materials engineer Louis Le Chatelier, an influential figure…

Florence Seibert and the Tuberculosis Test

Florence Seibert and the Tuberculosis Test

On October 6, 1897, American biochemist Florence Barbara Seibert was born. Seibert is best known for identifying the active agent in the antigen tuberculin as a protein, and subsequently for isolating a pure form of tuberculin, purified protein derivative (PPD), enabling the development and use of a reliable TB test. Youth and Education Seibert was born in Easton, Pennsylvania, USA, the second of three children of George Peter Seibert, a rug manufacturer…

Harrison Brown and the Isolation of Plutonium

Harrison Brown and the Isolation of Plutonium

On September 26, 1916, American nuclear chemist and geochemist Harrison Scott Brown was born. Brown is generally known for his role in isolating plutonium for its use in the first atomic bombs and for his studies regarding meteorites and the Earth’s origin. He also was a political activist, who lectured and wrote on the issues of arms limitation, natural resources and world hunger. Harrison Brown was born in Sheridan, Wyoming, USA, the…
