Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.

It was identified by Albert Ghiorso and co-workers at the University of California, Berkeley in collaboration with the Argonne and Los Alamos National Laboratories, in the fallout from the Ivy Mike nuclear test.

The new element was produced by the nuclear explosion in miniscule amounts by the addition of 15 neutrons to uranium-238.

Einsteinium is mainly used for scientific research purposes.

The rare isotope einsteinium-254 is favored for production of ultraheavy elements.

Einsteinium-254 was used as the calibration marker in the chemical analysis spectrometer of the Surveyor 5 lunar probe.
