On This Day - May 14 : First smallpox vaccination
The English doctor inserted pus from a cowpox pustule into an incision on the arm of eight-year old James Phipps. From then on Phipps was immune to smallpox, one of the most virulent killer diseases of the time.

On This Day - Jun 14 : Alois Alzheimer was born
He is recognised for identifying the first published cases of a progressive, degenerative brain disease that was eventually named after him. Today there are over 25 million sufferers of Alzheimer’s worldwide, but no known cure.

On This Day – Jul 14 : Sir William Perkin died
He synthesised the first artificial dyestuff, called mauve or aniline purple, while trying to synthesize quinine from a coal tar chemical. Perkin commercialised his discovery, developing production methods and uses for the new dye.

On This Day – Aug 14 : Hans Christian Ørsted born
He discovered that electric currents can create magnetic fields, an effect known as electromagnetism. He was also the first person to isolate aluminium (Al), which he did by reducing aluminium chloride.

On This Day - Oct 14 : Alfred Nobel first patent
This patent was for the preparation of nitroglycerine, and was the first of his 355 patents. Nobel is most famous for the prizes carrying his name, awarded annually since 1901 for outstanding achievement in physics, chemistry, physiology or medicine, literature and peace.

On This Day - Nov 14: First fullerene discovered
The new forms of the element carbon (C) were discovered by Robert Curl, Richard E. Smalley and Sir Harold W. Kroto. This opened up a new field of chemistry with applications including nanotechnology. They were jointly awarded the Nobel Prize in Chemistry in 1996 for this work.

On This Day - Dec 14 : Max Planck quantum theory
He presented his theoretical explanation of the spectrum of radiation emitted by an object that glows and introduced the notion of light as quantized energy packets to the German Physical Society.

On This Day - Apr 13 : Tellurium discovered
This semi-metal was discovered by Austro-Hungarian mineralogist Baron Franz Muller von Reichenstein. It is obtained as a grey powder and its compounds are not only poisonous, but even the tiniest amounts can lead to unpleasant body odours!

On This Day - May 13 : Johannes Thiele was born
He made a huge contribution to our knowledge of nitrogen (N)-containing compounds, leading to the discovery of numerous new compounds and synthetic processes. During WW1 he developed a gas mask against the effects of carbon monoxide (CO).

On This Day - Jun 13 : James Maxwell was born
Maxwell helped to formulate electromagnetic theory, which links magnetism, electricity and light. He also investigated the kinetic theory of gases and developed part of the Maxwell-Boltzmann distribution, which helps scientists to understand the effects of temperature on reaction rates.

On This Day – Aug 13 : Discovery of argon
The first noble gas to be discovered was argon, named after the Greek word ‘argos’ (meaning ‘lazy’) because it was completely unreactive. For this work, Sir William Ramsey was awarded the Nobel Prize in Chemistry and Lord Rayleigh the Nobel Prize in Physics in 1904.

On This Day – Sep 13 : Americium was made
This radioactive metal was first produced by B.B. Cunningham and L.B. Werner. Most americium is produced by bombarding uranium (U) or plutonium (Pu) with alpha particles – one tonne of spent nuclear fuel contains about 100 grams of americium. It has few uses other than in smoke alarms.

On This Day - Oct 13 : First zinc oxide
The Pennsylvania and Lehigh Zinc Company Mill produced zinc oxide (ZnO) from calamine ores. Zinc oxide is a white powder that is used as an additive to a wide range of products such as paints, plastics, adhesives, fire retardants and foods (nutrients).

On This Day - Nov 13 : Edward Doisy was born
He shared the Nobel Prize in Physiology or Medicine in 1943 for the isolation and synthesis of vitamin K, which encourages blood clotting and has several applications in medicine. Doisy also developed techniques that helped other scientists’ research sex hormones.

On This Day - Dec 13 : Charles Coulson was born
He was a pioneer of the application of quantum theory of particle valency to solve many chemical and physical problems, in particular in developing theories for molecular orbitals, dynamics and reactivity.

On This Day - Mar 12 : William Perkin was born
Credited with founding the organic chemical industry, Perkin discovered mauveine dye by accident when working with coal tar. Realising the commercial potential of this new purple dye, Perkin patented his synthetic process when he was just 18.

On This Day - Jun 12 : Fritz Lipmann was born
Lipmann was awarded half the 1953 Nobel Prize in Medicine for the discovery of coenzyme A and its role in nutrition. Coenzyme A is a molecule required in the synthesis and oxidation of fatty acids.

On This Day – Jul 12 : Discovery of xenon
The British chemists used a powerful machine that cooled and liquefied air to obtain krypton (Kr). They then repeatedly distilled the krypton until an even denser substance separated out, which they named xenon (Xe).

On This Day – Aug 12 : Phenol used in surgery
The British surgeon was a pioneer of antiseptic surgery and pushed the idea of sterile surgery while working at the Glasgow Royal Infirmary. Using sterile instruments and cleaning wounds were of great success and vastly reduced the number of people dying from post-operation infections from 50% to 15%.

On This Day – Sep 12 : Irène Joliot-Curie born
Like her parents, she was also a scientist. She and her husband Frédéric bombarded stable atoms with alpha particles to transmute them into different radioactive elements. They created nitrogen (N) from boron (B), phosphorus (P) from aluminium (Al), and silicon (Si) from magnesium (Mg).
