July 5, 1966, Freiburg im Breisgau, W.Ger.), chemist whose development of isotopic tracer techniques greatly advanced understanding of the chemical nature of life processes. This work earned him the 1943 Nobel Prize for Chemistry . He also discovered, with Dirk Coster, the element hafnium Educated at the Technische Hochschule in Berlin and the University of Freiburg, Hevesy in 1911 began work at the University of Manchester under Ernest Rutherford on the chemical separation of radium. Though his attempts proved unproductive, they stimulated him to explore the use of radioactive isotopes as tracers. He joined Friedrich Paneth at Vienna (1912) and made significant progress in tracer studies. Invited to Copenhagen (1920), he and Coster, pursuing a suggestion of Niels Bohr, discovered hafnium among ores of zirconium. Hevesy became professor at Freiburg (1926), where he began to calculate the relative abundance of the chemical elements. In 1934, after the preparation of a radioactive isotope of phosphorus, he began to study various physiological processes by tracing the course of "labeled" radioactive phosphorus through the body. These experiments revealed the dynamic state of the body constituents. Fleeing from the Nazis (1943), Hevesy became professor at the Institute of Organic Chemistry, Stockholm. His published works include the two-volume

Extractions: Working in Lord Rutherford's laboratory in Manchester (1913) this Hungarian-born scientist initiated the method of radioactive indicators as a tool in chemical analysis. After the First World War he spent six years at Niels Bohr's Institute in Denmark and, together with the Dutch physicist D. Coster, discovered a hitherto unknown element which was given the Latin name of Copenhagen: "Hafnium". In the 1930s Hevesy returned to Copenhagen and developed the tracer technique in biological and medical research using artificially produced radioactive isotopes. The wide applicability of this technique triggered spectacular advances in the life sciences and many other branches of science and technology. Hevesy was awarded the 1943 Nobel Prize for chemistry in 1944.

Had he been in a humorous mood, he might even have made this comment in the presence of George de Hevesy. January 1911. 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. His destination: the University of Manchesters Institute of Physics. His intent: to learn what he needed about electrical conductivity measurements in gases and return home. But the Hungarian-born chemist was entering the domain of Ernest Rutherford, and while there it was Rutherford who would control his fate. And Rutherford had a problem that Hevesy might help solve. He had recently acquired a considerable quantity of Radium D, a valuable byproduct of radium he hoped to make use of. The problem was that the Radium D was mixed up in a large quantity of lead, and the latter made it exceedingly difficult to investigate the radiations from the Radium D. So one day, by design or happenstance, Rutherford and his newly arrived chemist found themselves together in the laboratory basement where the radioactive lead was stored. Perhaps with a friendly arm on Hevesys shoulders, Rutherford issued a challenge, "My boy, if you are worth your salt, you separate Radium D from all that nuisance lead." (Levi 1985).

Extractions: 1) George de Hevesy; The first practical use of an radioisotope ... 5) Advantages and Problems of nuclear energy 1: George de Hevesy; The first practical use of an radioisotope "The first practical application of a radioisotope was made by George de Hevesy in 1911. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed." De Hevesy went on to win the Nobel Prize in 1943 and the Atoms for Peace award in 1959. He contributed much to the world of nuclear energy. He made a great impact in the nuclear field but amongst his achievements he was responsible for pioneer work in the use of isotopic indicators and he was involved in the first clinical use of isotopes. "De Hevesy also carried out several investigations with radioactive sodium and potassium. He studied how physiological saline containing radioactive sodium which was injected into a human subject first spread into the blood and then slowly penetrated into the cells; he also studied the manner in which it is excreted. After 24 hours the blood corpuscles had lost approximately half their sodium content."

George de Hevesy was born in Budapest on Aug. 1, 1885. He studied at Freiburg, Zurich, and Karlsruhe and in 1911 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 1913 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.

Extractions: He interrupted early in 1913 his studies to carry out jointly with Frederic Paneth the first radioactive-tracer experiment at the Vienna Institute of Radium Research. His early investigations involved a study of the chemical behavior of molten salts and his introduction to practical radiochemistry came in Rutherford's laboratories at Manchester. His work there, and later in Vienna and Budapest, mainly concerned the investigation and use of radium and lead isotopes. He was awarded the Cannizaro Prize in 1929, he was the Copley Medallist in 1949, Faraday Medallist in 1950, Baily Medallist in 1951 and silvanus Thompson Medallist in 1955. In 1959 he received the Ford foundation's Atoms for Peace Award Medal, in 1961 the Niels Bohr Medal and the Rosenberger Medal of the University of Chicago. He was awarded the Nobel Prize In Chemistry 1943 "for his work on the use of isotopes as tracers in the study of chemical processes".

Female authors published freely under their own names, but Eliot wanted to ensure that she was not seen as a writer of romances.

He wrote a number of works, the most widely-read of which are his Treatise Concerning the Principles of Human Knowledge ) and Three Dialogues between Hylas and Philonous ) (Philonous, the "lover of the mind", representing Berkeley himself).
