George de Hevesy

George de Hevesy , or George von Hevesy (1885 - July 5th 1966) is a Chimiste Hungarian, prize winner of the Nobel Prize of chemistry in 1943.

George de Hevesy studies the Chimie with the Université of Budapest, with the technical Université of Berlin then to the Université of Freiburg-in-Brisgau of which it is graduate in 1908. In 1910, it leaves to study with the the United Kingdom with Manchester under the direction of Ernest Rutherford (Nobel Prize of chemistry 1908). In 1913, it takes part with Frederic Paneth in the Research institute on the radium of Vienna in the first experiment of use of radioactive tracers. In 1920, it settles with Copenhagen to work in the institute of Niels Bohr (future Nobel Prize of physics in 1922). In 1926, it turns over to Freiburg-in-Brisgau as professor of physical Chimie, then in 1930 with the Université Cornell with Ithaca (New York). From 1934 to 1952, he works again with the Institut Niels Bohr. When the army Nazi invades the Denmark, it dissolves the gold medals of the Nobel Prize of max von Laue and James Franck in the Eau levels and preserves the bottle in its office of the Institut Niels Bohr. After the war, it makes reprécipiter the Or, it returns it to the Fondation Nobel which strikes again the medals. With its retirement, it continues its scientific activities in collaboration with the Université of Stockholm.

The first scientific activities of George de Hevesy relate to the chemical behavior of melted salts, but it is interested quickly in the study of the radioactive Isotope S . With Copenhagen, it is interested in separation of the isotopes and contributes to discovered of the Hafnium in 1923 with Dirk Coster. It belongs to the pioneers for the use of radioactive isotopes like tracers, initially in chemical reactions, then for medical uses. It also is interested in the effect of the X-rays on the Nucleic acid in the cancer cells and healthy.

George de Hevesy is prize winner of a great number of scientific distinctions, among which one can quote:

the Nobel Prize of chemistry in 1943 for its work in the field of the radioactive tracers
the Price Cannizzaro of the Academy of Science Italian in 1929
the Medal Copley of the Royal Society of London in 1949
the Faraday Lectureship of the Royal Society off Chemistry British in 1950
the Medal Baily in 1951
the Medal Sylvanus Thompson in 1955
the Atoms for peace award in 1959
the Medal Niels Bohr in 1961.

He is the author of many works, of which: Das Element Hafnium (the element Hafnium) in 1927, Chemical Analysis with X-Rays (chemical Analysis by x-rays) in 1932, and Radioactive Indicators (Tracer radioactive) in 1948.
