Prize share: 1/1
George de Hevesy was born in Budapest to a wealthy Christian family with Jewish heritage. After graduating from the Gymnasium of the Piarist Order, George de Hevesy studied at Budapest University, Berlin Technical University, and the University of Freiburg in Breisgau. Following that, George de Hevesy worked at a number of European universities. He was granted a professorship at Freiburg University in 1926, but later fled Nazism in 1934, arriving first in Copenhagen before moving on to Stockholm in 1943, where he worked at the University of Stockholm until his death. George de Hevesy was married with four children.
Tracking various elements through different processes is important in understanding how organisms work. After failing to separate an isotope of radium from lead in 1913, George de Hevesy realized that lead could be "marked" using the isotope. Radium is radioactive, and by measuring radiation emitted from it, he could study lead's journey through different processes. George de Hevesy published the first studies to use the method in 1923. The method has since come to play a key role in chemistry and biology.
Their work and discoveries range from how cells adapt to changes in levels of oxygen to our ability to fight global poverty.
