Karl Manne Georg Siegbahn
The Nobel Prize in Physics 1924
Born: 3 December 1886, Örebro, Sweden
Died: 26 September 1978, Stockholm, Sweden
Affiliation at the time of the award: Uppsala University, Uppsala, Sweden
Prize motivation: "for his discoveries and research in the field of X-ray spectroscopy."
Manne Siegbahn received his Nobel Prize one year later, in 1925.
Prize share: 1/1
A few years after the discovery of X-rays, Charles Barkla showed that compounds exposed to X-rays emitted secondary X-rays with wavelengths that were characteristic of different elements. After studying a number of elements, Henry Moseley was able to add to and revise the periodic table. Manne Siegbahn developed apparatus and methods for improving accuracy when mapping x-ray spectra. This advance proved important in the development of atomic and quantum physics.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
