HYoVEShI of Dyyord (Hevesy Gyorgy Jozsef, 1885 — 1966) — the Hungarian chemist and fizikokhimik, the honorary academician of the Hungarian academy of Sciences, the Nobel Prize laureate (1943).

Studied at Budapest un-those,

the Higher technical school at Berlin and Freyburg-sk un-those. In 1908 protected dokt. thesis. Till

1911 taught in Zurich un-those, then worked in Manchester in laboratory E. Rutherford and in Vienna in-those radium. During World War I served in Austro-Hungarian army. After war professor un-that in Budapest (1918 — 1920), since 1920 worked in laboratory of Bor (N. H. D. Bohr) in Ying-those theoretical physics in Copenhagen. In 1926 headed department of physical chemistry in Freyburgskom un-those. After coming to power in Germany of fascists in 1934 returned to Copenhagen, and then in 1943 moved to Stockholm where continued the researches in Ying-those organic chemistry.

D. Hevesha's works are devoted to studying of radioactivity (see), to use of radioisotopes as tags. In 1913 D. Hevesha and F. Paneth offered a method of tracers — marked atoms (see. Marked connections) also applied it to studying of metabolism of compounds of lead and bismuth in an organism of animals and the person. Further D. Hevesha studied a possibility of use of artificial radioisotopes (32P; 14C, etc.) in biological and medical researches. In 1922 together with D. Coster hafnium was open and emitted to them chemical element. In 1931 D. Hevesha developed the isotope dilution method which found broad application in experimental medicine and radio-isotope diagnosis (see) in 1932 — a method of the X-ray fluorescent analysis, and in 1936 together with the Hungarian chemist D. Levi — a method of the neytronoaktivatsionny analysis (see. Activation analysis). The Nobel Prize is conferred for works in the field of chemistry.

D. Hevesha — the winner of the International award «Atom for the World» (1959), award E. Fermi, the foreign member London royal
