Paneth, Friedrich Adolf

(frē`drĭkh ä`dôlf pä`nĕt), 1887–1958, Austrian chemist. He was educated at Vienna, Munich, and Glasgow. He held a number of teaching posts in Germany until he was forced into exile in England in 1933. After World War II he returned to Germany as director of the Max Planck Institute for Chemistry at Mainz. Among Paneth's contributions to the study of radioactivity was the demonstration that lead and radium-D, a product of the radioactive decay of radium, are chemically inseparable, a fact which led him to develop, with Georg von Hevesy, the technique of isotopic labeling (see isotopeisotope
, in chemistry and physics, one of two or more atoms having the same atomic number but differing in atomic weight and mass number. The concept of isotope was introduced by F.

). Their work laid the foundation of modern radioactive tracer techniques.

Paneth, Friedrich Adolf

 

Born Aug. 31, 1887, in Vienna; died there Sept. 17, 1958. German chemist and geo-chemist.

After completing his studies at the universities of Vienna, Munich, and Glasgow, Paneth conducted research in related fields of chemistry, geology, and astronomy. He taught at the Prague Institute of Technology and at the universities of Hamburg and Berlin. He also lectured on atomic chemistry at the Imperial College of Science and Technology in London. From 1939 to 1953 he was a professor at Durham, and in 1953 he was appointed director of the Max Planck Institute of Chemistry at Mainz. He was the first to study the absolute age of meteorites, formulating a precise method of determining the helium content of meteorites.

Paneth was a member of the Royal Society of London from 1947, an honorary member of many scientific associations, and president of the Joint Commission on Radioactivity of the International Council of Scientific Unions from 1949.
