Centenary for the detection of hafnium – a contribution from the Univ. of Oslo

The internationally recognised Norwegian geochemist, Victor Moritz Goldschmidt ("Father of modern geochemistry", 1888-1947), was based at the Geological Institute and the Mineralogical-Geological Museum (merged into NHM in 2000) at the University of Oslo.

Victor Moritz Goldschmidt's research, in collaboration with W.C. Brøgger, started when he was in high school, and his first scientific article (Goldschmidt, 1906) was published when he was 18 years old.  His biography, written by Mason (1992), is freely available from the Geochemical Society.

One hundred years ago, element 72, hafnium, was named for the latin name of Copenhagen (Hafnia) because Coster & Hevesy (1923) in the research group of Niels Bohr detected the element 29 days before Goldschmidt & Thomassen (1923) in Oslo.

Two blog articles (en/no) describe the detection of hafnium and other neighbouring elements, as well as the geochemical importance of hafnium. 

The blog articles were published at blog.forskning.no in December 2023 in Reidar G. Trønnes' blogg.
