Learn about the history of science by reading about the significant scientific events that took place on this day in history.
1918 - Ernst Otto Fischer was born.Fischer was a German chemist who shares the 1973 Nobel Prize in Chemistry with Geoffrey Wilkinson for their independent pioneering work with organometallic compounds. He worked on compounds with transition metal complexes and catalysts to hydrogenate alkenes into alkanes. He also identified the structure of the sandwich compound, ferrocene.
1861 - Robert T. A. Innes was born.
Innes was a Scottish astronomer who discovered Proxima Centauri, the star closest to Earth. Over the course of his career, he discovered 1600 double star systems. He also converted a Johannesburg, South Africa meteorological station into the astronomical observatory known as Union Observatory.
1799 - Joseph Black died.
Black was a Scottish chemist who was one of the founders of thermochemistry. He discovered that when ice melts, the temperature does not change leading to the idea of specific or latent heat. He also researched carbon dioxide or what he called 'fixed air'. This research led to the discovery of bicarbonates.
1764 - Andrés Manuel Del Rio was born.
Rio was a Spanish mineralogist who discovered the element vanadium. He named the his discovery pancromium and sent his samples to be verified. They were mistakenly identified as chromium and his claim was rejected. Twenty nine years later, Swedish chemist Nils Sefström rediscovered the element and named it vanadium.
