George Charles de Hevesy
The Hungarian chemist George Charles de Hevesy () was a pioneer of isotope labeling and codiscoverer of the element hafnium.
George de Hevesy was born in Budapest on Aug. 1, He studied at Freiburg, Zurich, and Karlsruhe and in joined Ernest Rutherford at Manchester. His assignment there, to separate radium-D from lead, proved impossible, because radium-D, as was later demonstrated, actually comprises isotopes. Yet the 2 years were not wasted, for Hevesy gained valuable technical experience in the new field of radiochemistry. In he left for Vienna to join F. A. Paneth, whose experience with radium-D had been similar. They studied the exchange between radioactive and nonradioactive lead atoms, showing that, for all ordinary processes, the chemical and physical behavior of these atoms was identical. Also, by using radioactive (labeled) samples to determine the solubilities of various lead salts, they introduced the technique of radioactive tracers.
In Hevesy moved to Niels Bohr's institute at Copenhagen, where his attention was directed to the possibility of separating isotopes. In Hevesy, working with J. N. BrÓnsted, effected a partial separation o
George de Hevesy, father of nuclear medicine
In the beginning of the 20th century, research into physiological and anatomical processes was in full swing. Basic questions about how the nervous system functions, the role bacteria play in disease, as well as our understanding of the immune system were being explored.
But scientists&#; understanding of the inner workings of the body was still limited. Living organisms were only understood in basic terms and knowledge about anatomy and medicine was, for the most part, gained through posthumous dissection.
With the advent of the X-ray machine in , our ability to look inside the body changed drastically. However, this technology was still in its infancy and only provided brief (albeit important) snapshots of what was going on. The ability to observe biological processes in real time without disrupting them or causing any damage was still not yet a reality.
But all this changed with the advent of radiotracers, developed in the s by George de Hevesy. These are radioactive elements that can be tracked through various chemical and biological processes, allowing scientists to gain a deeper understanding of how organisms work.

Biography of Georg de Hevesy
Georg de Hevesy was born on August 1, , in Budapest, Hungary. He was one of eight children born to Louis de Hevesy, a judge and manager of a mining company and several family farms, and Baroness Eugenia Schossberger.
Hevesy showed a keen interest in mathematics and physics from an early age and graduated from a church school in Budapest in He then attended the Budapest University for a year before transferring to the Berlin Institute of Technology. Due to poor health, he moved to the University of Freiburg in southern Germany, where he completed his doctoral degree in with a dissertation on the interaction of sodium with caustic soda melts.
For the next two years, Hevesy worked at the Federal Institute of Technology in Zurich under the guidance of Richard Lorenz, a renowned expert in the chemistry of molten salts. During his time in Zurich, he attended lectures by Albert Einstein, who was working at the University of Zurich, and visited his laboratory.
In , Hevesy spent three months in Karlsruhe, Germany, collaborating on research with Fritz Haber. He
George Charles de Hevesy
George Charles von Hevesy, also known as George Charles de Hevesy, was born on August 1, , in Budapest, Austria-Hungary (now Hungary). Hevesy attended college at the Technische Hochschule in Berlin and the University of Freiburg. He began his work in chemistry in at the University of Manchester under Ernest Rutherford, which stimulated him to experiment with isotopic tracers. In , Hevesy moved to Vienna, Austria to collaborate with Friedrich Paneth.
In , Hevesy was a co-discoverer with Dirk Coster of the chemical element hafnium. He became a professor at the University of Freiburg in where he determined the comparative quantity of chemical elements. In , Hevesy began to trace a radioactive isotope of phosphorus through the human body to study chemical processes.
After fleeing from the Nazis in , Hevesy was awarded the Nobel Prize for Chemistry for his work with radioactive isotopes. Hevesy was the pioneer in scrutinizing the biochemical courses in living bodies by introducing radioactive isotopes or isotopic tracers. This process became know as the tracer method and sophisticated the world’s knowledge of chemical sequences that take place in life c
