Happy Bicycle Day

Happy Bicycle Day

On April 19, 1943, Swiss chemist Albert Hofmann in the Sandoz (now Novartis) laboratories in Basel, Switzerland performed a self-experiment to determine the true effects of LSD, intentionally ingesting 0.25 milligrams (250 micrograms) of the substance, an amount he predicted to be a threshold dose (an actual threshold dose is 20 micrograms). While riding home on his bicycle, he experienced the very first LSD trip, now referred to as “Bicycle Day”, and proved…

Otto Hahn – the Father of Nuclear Chemistry

Otto Hahn – the Father of Nuclear Chemistry

On March 8, 1879, German chemist and pioneer in the fields of radioactivity and radiochemistry Otto Hahn was born. He was awarded the Nobel Prize in Chemistry in 1944 for the discovery and the radiochemical proof of nuclear fission at the exclusion of his colleague Lise Meitner. He is referred to as the father of nuclear chemistry. Otto Hahn studied chemistry and mineralogy at the University of Marburg. During his third and fourth semester,…

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 as assistant…

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 movement of…

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 Ludwig-Maximilians-University of…

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 in Hannover,…

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 reaction, 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 minister, and…

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. Mikhail Lomonosov…

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. Eventually, he…
