  George de Hevesy Summary
The Hungarian chemist George Charles de Hevesy (1885-1966) was a pioneer of isotope labeling and codiscoverer of the element hafnium.
George de Hevesy was born in Budapest on Aug. 1, 1885.
George Charles de Hevesy (born as Hevesy György, also known as Georg Karl von Hevesy) (August 1, 1885 in Budapest – July 5, 1966) was a Hungarian chemist who was important in the development of the tracer method where radioactive tracers are used to study chemical processes, e.g., the metabolism of animals.

 Four stories about George de Hevesy
George de Hevesy had good reason to regret crossing the English Channel - the resulting seasickness laid him up in bed for two weeks before he could continue his journey.
Whether or not Hevesy made tea from it is not recorded, but he and his new drinking buddy, E. Hofer, consumed the stuff in 150, 250, and for the sake of precision, 2000 ml aliquots.
Hevesy might have been disappointed that he could no longer claim priority to a theory that once "shook the earth," but he would henceforth make a point of giving the saint full credit.

 JCE 2002 (79) 301 [Mar] A Century of Chemical Dynamics Traced through the Nobel Prizes. 1943: George de Hevesy
The fourth Nobel Prize for research related directly to chemical dynamics was awarded to George de Hevesy in 1943 "for his work on the use of isotopes as tracers in the study of chemical processes".
de Hevesy's interest in isotopes stemmed from his work with Ernest Rutherford in Manchester when they found that it was impossible to separate various lead isotopes resulting from the radioactive decay of radium.
This led de Hevesy to the conclusion that if isotopes could not be separated by ordinary chemical means, then isotopes could be used as tracers in research on chemical and physiological processes.

Hevesy was born in 1885, in Budapest under the name of Bischitz, which, as it often happened in christianized Jewish families then, was changed to the Hungarian name of Hevesy in 1906.
Hevesy began to apply this method in the field of biology in 1923 but as the radioactive isotopes at his disposal, being heavy metals, were poisonous for living organisms, he put this direction of research aside.
Hevesy was considered as a founding father of a commonly used technique, which was and remained recent as a standard method in many kinds of investigations inside and outside science.

 NS&T : History : Hall of Fame : George von Hevesy
Hevesy had just joined the research group at the University of Manchester headed up by Rutherford who was investigating the radioactive properties of radium-D (Pb-210).
Out of his failure to complete that impossible task, Hevesy conceived the radiotracer technique by which radioisotopes could be used to investigate the behavior of stable atoms.
Hevesy not only performed the first radiotracer studies on plants and animals, using both natural and artificial radionuclides, he also performed the first tracer studies employing stable nuclides by using deuterated water to measure the turnover of hydrogen in the body.

 Hevesy, Georg von   (Site not responding. Last check: )
Hevesy was born in Budapest and educated in Germany, Switzerland, and the UK, studying at Manchester under nuclear-physics pioneer Ernest Rutherford 1911.
Hevesy first used radioactive tracers to study the chemistry of lead and bismuth salts.
During the early 1930s, he began experiments with this technique on biological specimens, noting the take-up of radioactive lead by plants, and going on to use an isotope to trace the movement of phosphorus in the tissues of the human body.

George de Hevesy (also known as George von Hevesy) received the Nobel Prize in Chemistry in 1943 for his his work on the use of isotopes as tracers in the study of chemical and biological processes.
It is interesting that Hevesy's first use of radioactive tracers in 1923 was hardly noticed by chemists and biologists at the time, but before long his methods became the foundation for enormous progress in chemical dynamics, biochemistry, and physiology.
For example, using deuterium-enriched water provided by Harold Urey (1893-1981), de Hevesy found that fish and amphibians swimming in that water take up deuterium and come to equilibrium with their environment with respect to deuterium in about four hours, and that humans who drink D2O excrete deuterium in their urine in approximately 26 minutes.

 CSHL: Symposia on Quantitative Biology
Demerec recognized that other meetings had been held on tracers but, he claimed, this Symposium would be the first to focus on biological experimentation rather than on the physics and chemistry of making tracers.
Unfortunately, Demerec persisted in printing contributions in alphabetical order of authors, but George de Hevesy's detailed historical paper was presumably the opening contribution (de Hevesy had won the Nobel Prize for Chemistry in 1931).
The power of the tracer approach for unraveling biochemical syntheses is illustrated by the presence of two future Nobelists reporting on the early stages of their research.

Established in 1968 by the Editor-in-Chief and the (then) publishers of the Journal of Radioanalytical and Nuclear Chemistry (JRNC), the Hevesy Medal Award is given in recognition of excellence through outstanding, sustained career achievements in the fields of pure and applied nuclear and radiochemistry, particularly applications to nuclear analytical chemistry.
The Hevesy Medal was awarded almost annually during the period 1968-86 to nineteen distinguished individuals whose contributions had traced and defined the scope and depth of radioanalysis through the prolific postwar years of the nuclear era.
