About George Charles Karl de Havesey (Bischitz), Nobel Prize in Chemistry, 1943

George Charles de Hevesy, Georg Karl von Hevesy, (1 August 1885 – 5 July 1966) was a Hungarian radiochemist and Nobel laureate, recognized in 1943 for his key role in the development of radioactive tracers to study chemical processes such as in the metabolism of animals.

Biography

Early years

Hevesy György was born in Budapest, Hungary to a Roman Catholic family of Hungarian Jewish descent, the fifth of eight children from his wealthy parents Lajos (Louis) Bischitz and Eugenia (Jenny) Schossberger. George grew up in Budapest and graduated high school in 1903 from Piarista Gimnázium. The family's name in the 1904 was Hevesy-Bischitz, and Hevesy later changed his own.

De Hevesy began his studies in chemistry at the University of Budapest for one year, and at the Technical University of Berlin for several months, but changed to the University of Freiburg. There he came in contact with Ludwig Gattermann. In 1906 he started his Ph.D. thesis with Georg Franz Julius Meyer, acquiring his doctorate in physics in 1908. In 1908 Hevesy got a position at the ETH.

Research

When Richard Lorenz left for the University of Frankfurt and Richard Willstätter tried to convince him to stay in Zurich he decided to go to the University of Karlsruhe to work with Carl Bosch. To learn new methods, de Hevesy joined Ernest Rutherford's laboratory at the University of Manchester in 1911 where he met and became friends with Niels Bohr.

In 1923 de Hevesy co-discovered hafnium (72Hf) (Latin Hafnia for "Copenhagen", the home town of Niels Bohr), with Dirk Coster. Mendeleev's periodic table in 1869 put the chemical elements into a logical system, however there was missing a chemical element with 72 protons. On the basis of Bohr's atomic model Hevesy came to the conclusion that there must be a chemical element that goes there. The mineralogical museum of Norway and Greenland in Copenhagen furnished the material for the research. Characteristic X-ray spectra recordings made of the sample indicated that a new element was present. This earned him the 1943 Nobel Prize in Chemistry.

Hevesy was offered and accepted a job from the University of Freiburg. Supported financially by the Rockefeller Foundation, he had a very productive year. He developed the X-ray florescence analytical method, and discovered the Samarium alpha-ray. It was here he began the use of radioactive isotopes in studying the metabolic processes of plants and animals, by tracing chemicals in the body by replacing part of stable isotopes with small quantities of the radioactive isotopes. [edit] World War II and beyond

When Germany invaded Denmark in World War II, de Hevesy dissolved the gold Nobel Prizes of Max von Laue and James Franck with aqua regia to prevent the Nazis from stealing them. He placed the resulting solution on a shelf in his laboratory at the Niels Bohr Institute. After the war, he returned to find the solution undisturbed and precipitated the gold out of the acid. The Nobel Society then recast the Nobel Prizes using the original gold.

In 1943, Copenhagen was no longer seen as safe for a Jewish scientist, and de Hevesy fled to Sweden, where he worked at the Stockholm University College until 1961. Interestingly enough, in Stockholm, de Hevesy was received at the department of German-Swedish professor and Nobel Prize winner Hans von Euler-Chelpin, who remained strongly pro-German throughout the war. Despite this, de Hevesy and von Euler-Chelpin collaborated on many scientific papers during and after the war.

During his time in Stockholm, de Hevesy received the Nobel Prize in chemistry. He later was inducted as a member of the Royal Society and received the Copley Medal, of which he was particularly proud. De Hevesy stated: "The public thinks the Nobel Prize in chemistry for the highest honor that a scientist can receive, but it is not so. Forty or fifty received Nobel chemistry prizes, but only ten foreign members of the Royal Society and two (Bohr and Hevesy) received a medal-Copley." George de Hevesy was elected a foreign member of the Royal Swedish Academy of Sciences in 1942, and his status was later changed to Swedish member. In 1949 he was elected Franqui Professor in the University of Ghent. He received the Atoms for Peace Award in 1958 for his peaceful use of radioactive isotopes. George de Hevesy's grave in Budapest. Cemetery Kerepesi: 27 Hungarian Academy of Sciences.

De Hevesy married Pia Riis in 1924. They had one son and three daughters together. De Hevesy died in 1966 at the age of eighty and was buried in the Kerepesi Cemetery in Budapest, Hungary. He had made a total of 397 scientific publications. At his family's request, his ashes were interred at his birthplace in Budapest on April 19, 2001. -------------------- they had 1 son and 3 daughters

Early years


Hevesy György was born in Budapest, Hungary to a wealthy and ennobled Hungarian Jewish[1] family, the fifth of eight children to his parents Lajos (Louis) Bischitz and Baroness Eugenia (Jenny) Schossberger (ennobled as "De Tornya"). Grandparents from both sides of the family had provided the presidents of the Jewish community of Pest.[2] George grew up in Budapest and graduated high school in 1903 from Piarista Gimnázium. The family's name in the 1904 was Hevesy-Bischitz, and Hevesy later changed his own.
