- Discoveror: Workers at Argonne, Los Alamos, USA, and the University of California at Berkeley, USA.
- Place of discovery: USA

Fermium was identified by Ghiorso and coworkers (Berkeley, California, USA) in 1952 in the radioactive debris from a thermonuclear explosion in the Pacific. Somewhat remarkably, the fermium isotope discovered was made through the combination of 238U with 17 neutrons. Today, many isotopes are known spanning the mass range 243-258.
