OBITUARY F.A.PAHSTE1667-lQ56 FRIEDRICH ADOLPH PANETH, one of the founders and original editors of this journal, died in Vienna on 17 September 1958. Born in Vienna in 1887, he received his early training at the Universities of Vienna, Munich and Glasgow, respectively under Skraup, von Baeyer and Soddy. He occupied Chairs at the Prague Institute of Technology, at the universities of Hamburg and Berlin and was Professor and Director of the Chemical Laboratories at Koenigsburg before coming to England to work at Imperial College, being appointed in 1938 Reader in Atomic Chemistry. In 1939 he became Professor of Chemistry at Durham. His earlier work included the development of the use of radioactive tracers, the discovery of the hydrides of several metals and studies of the transient free aliphatic radicals. In later life his interests turned towards geochemistry and cosmochemistry; he devised precise methods for the determination of helium and among other tasks he was entrusted with the investigation of gases collected from the upper atmosphere by rocket missiles fired in the United States. He also applied the helium method to the determination of the ages of meteorites. His distinguished contributions to chemistry were recognized in 1947 by his election to the Royal Society, and by honours from many other learned societies. In 1949 he wss President of the Joint Commission on Radioactivity of the International Council of Scientific Unions. During World War II he spent 2 years as Head of the Chemistry division of the BritishCanadian Atomic Energy Laboratory in Montreal. Upon returning to Durham, his efforts led to the foundation of the Londonderry Laboratory for Radiochemistry to which he attracted researchers from many parts of the world. He retired from the Durham Chair in 1953, and became a Director in the Max-Planck-Institiit fiir Chemie, Mainz. A man of great personal charm and of formidable linguistic ability, Professor Paneth will be remembered by friends in many countries, not least by those who work in the borderland between chemistry, geology and astronomy.
