Ira Remsen and the Discovery of Saccharin

On February 10, 1846, American chemist Ira Remsen was born. Along with his student Constantin Fahlberg, Remsen discovered the artificial sweetener saccharin working on coal tar derivatives. “Be a physical chemist, an analytical chemist, an organic chemist, if you will; but above all, be a chemist.” – Ira Remsen, as quoted in [8] Ira Remsen – Early Years Ira Remsen was born in New York City. His parents were both descended from…

Ilya Prigogine and the Irreversibility of Time

Ilya Prigogine and the Irreversibility of Time

On January 25, 1917, Belgian physical chemist and Nobel Laureate Ilya Prygogine was born. He is noted for his work on dissipative structures, complex systems, and irreversibility. The main theme of Prigogine‘s work was the search for a better understanding of the role of time in the physical sciences and in biology. He attempted to reconcile a tendency in nature for disorder to increase with so-called “self-organisation“. Youth and Education Prigogine was born…

Robert Boyle – The Sceptical Chemist

Robert Boyle – The Sceptical Chemist

On December 31, 1691, Anglo-Irish natural philosopher, chemist, physicist and inventor Robert Boyle passed away. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle’s law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant…

Joseph Louis Gay-Lussac and his Work on Gases

On December 6, 1778, French chemist and physicist Joseph Louis Gay-Lussac was born. He is known mostly for two laws related to gases, and for his work on alcohol-water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries. “I have not chosen a career that will lead me to a great fortune, but not my principal ambition. In fact, later in life he enjoyed comfortable income…

Nicolas Lemery and the Acid-Base Chemistry

On November 17, 1647, French chemist Nicolas Lémery was born. Lemery was one of the first to develop theories on acid-base chemistry in a time which was often referred to as “the dawn of scientific chemistry” . Nicolas Lemery was the fifth of seven children born in Rouen, France, to Julien Lemery, a Protestant attorney in the Parlement of Normandy. After being apprenticed to his uncle,a pharmacist in his native town Rouen,…

Antoine Lavoisier’s Theory of Combustion

Antoine Lavoisier’s Theory of Combustion

On Nov 1,1772, French chemist Antoine Lavoisier reported in a note to the Secretary of the French Academy of Sciences about the role of “air” in the combustion process. It required five more years of experiments, before in 1777, Lavoisier was ready to propose a new theory of combustion that excluded phlogiston, which according to the prevailing theories of the time was part of every matter and responsible for the combustion process. Modern chemistry…

Georg Ernst Stahl and the Phlogiston Theory

Georg Ernst Stahl and the Phlogiston Theory

On October 22, 1659, German chemist, physician and philosopher Georg Ernst Stahl was born. Stahl developed the phlogiston theory of combustion and of such related biological processes as respiration, fermentation, and decay. Combustible objects, he said, were rich in phlogiston, and during combustion is lost. The remaining ash, now having no phlogiston, could no longer burn. Until the late 18th century his works on phlogiston were accepted as an explanation for chemical…

Christian Friedrich Schönbein and the Ozone

On October 18, 1799, German-Swiss chemist Christian Friedrich Schönbein was born. Schönbein is best known for inventing the fuel cell (1838) and his discoveries of guncotton (nitrocellulose) and ozone. Christian Friedrich Schönbein was apprenticed at a pharmaceutical factory in Böblingen and was adviced to begin studying at the university. Schönbein enrolled at the University of Erlangen in 1820 were he got to know Justus Liebig Friedrich Schelling, who later helped Schönbein to finance…

Wilhelm Ostwald and the Foundation of Modern Physical Chemistry

On September 2, 1853, Baltic German chemist and Nobel Laureate Wilhelm Ostwald was born. He is credited with being one of the modern founders of the field of physical chemistry and received the 1909 Nobel Prize in Chemistry for his work on catalysis, chemical equilibria and reaction velocities. „Katalyse ist die Beschleunigung eines langsam verlaufenden chemischen Vorgangs durch die Gegenwart eines fremden Stoffes.“ – Wilhelm Oswald, 1894 Wilhelm Ostwald – Early Life…
