Biography
George Charles de Hevesy was born György Bischitz on August 1, 1885, in Budapest, Hungary, in a wealthy Jewish family. His father was a successful industrialist, allowing young György to receive an excellent education. He started his studies at the Piarist Gymnasium in Budapest and went on to study chemistry at top European universities such as the University of Freiburg, Eötvös Loránd University in Budapest, and the Technische Universität Berlin. Throughout his early academic career, he traveled across Europe, working with some of the leading scientists of his era.
De Hevesy made his scientific breakthrough with his pioneering work using radioactive isotopes as tracers in chemical and biological processes. This groundbreaking technique allowed researchers to track the movement and transformation of elements in living organisms and chemical reactions with great precision. It opened new paths for understanding metabolism, plant nutrition, and cellular processes. The method became incredibly valuable in medical research, helping scientists study how substances move through the human body without needing invasive procedures.
In 1922, de Hevesy worked with Dirk Coster in Copenhagen to co-discover element 72, which they named hafnium after the Latin name for Copenhagen. This discovery backed up theoretical predictions about the periodic table and filled an important gap in understanding the elements. During this time, he did much of his work at the Institute for Theoretical Physics in Copenhagen under Niels Bohr, where he made many key contributions to radiochemistry.
De Hevesy's career covered some of Europe's most unsettled times. As a Jew, he faced growing persecution as Nazi Germany rose to power and had to escape to Sweden in 1943, the year he received the Nobel Prize in Chemistry. He spent his later years researching and teaching, eventually settling in Sweden and later Germany. He passed away on July 5, 1966, in Freiburg im Breisgau, leaving a scientific legacy that changed the fields of chemistry, biology, and medicine.
Before Fame
De Hevesy grew up during a time of great scientific discovery in Central Europe, when Budapest was an active hub of intellectual activity in the Austro-Hungarian Empire. His privileged background allowed him to study with top chemists across Europe, including Fritz Haber in Berlin and Ernest Rutherford in Manchester. The early 20th century saw fast advances in understanding atomic structure and radioactivity, discoveries by scientists like Henri Becquerel, Marie Curie, and Ernest Rutherford that laid the groundwork for de Hevesy's later work.
His rise to fame began when he faced the challenge of separating radioactive isotopes from their non-radioactive counterparts while working in Rutherford's lab. Instead of seeing it as a setback, de Hevesy saw it as a chance, realizing that the inseparability of isotopes could be used to trace chemical processes. This idea became the core of his scientific career and groundbreaking contributions to many areas of science.
Key Achievements

Did You Know?
- 01.De Hevesy reportedly dissolved his and Max von Laue's Nobel Prize gold medals in aqua regia to hide them from Nazi authorities, then recovered the gold after the war and had the medals recast
- 02.He used radioactive tracers to prove that his landlady was serving him reheated food by detecting the isotopes in his meals days later
- 03.The element hafnium he co-discovered was found by X-ray spectroscopy analysis of Norwegian zircon crystals
- 04.He was forced to change his surname from Bischitz to de Hevesy due to anti-Semitic pressures in academia
- 05.De Hevesy's radioactive tracer technique was first demonstrated using plants, showing how they absorb and distribute nutrients
