  It's Elemental - The Element Einsteinium
Einsteinium was discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the radioactive debris produced by the detonation of the first hydrogen bomb.
Today, einsteinium is produced though a lengthy chain of nuclear reactions that involves bombarding each isotope in the chain with neutrons and then allowing the resulting isotope to undergo beta decay.
Einsteinium's most stable isotope, einsteinium-252, has a half-life of about 471.7 days.

 Einsteinium Summary
Einsteinium is a synthetic element in the periodic table that has the symbol Es and atomic number 99.
A metallic highly radioactive transuranic element (7th in the series) in the actinides, einsteinium is produced by bombarding plutonium with neutrons and was discovered in the debris of the first hydrogen bomb test.
Einsteinium was first identified in December 1952 by Albert Ghiorso at the University of California, Berkeley and another team headed by G.R. Choppin at Los Alamos National Laboratory.

Einsteinium is a member of group IIIb of the periodic table; its chemical properties are believed to be similar to those of the other members of the actinide series.
The seventh transuranium element to be discovered, einsteinium was isolated in Dec., 1952, by Albert Ghiorso and his coworkers at the Univ. of California at Berkeley in residue from the first thermonuclear test explosion in the South Pacific.
It was not until 1961 that a weighable quantity (about 0.01 microgram) of the element was separated; it was used to prepare the element mendelevium.

Einsteinium, the seventh transuranic element of the actinide series to be discovered, was identified by Ghiorso and co-workers at Berkeley in December 1952 in debris from the first large thermonuclear explosion, which took place in the Pacific in November 1952.
This was then fabricated into pellets of plutonium oxide and aluminum powder, and loaded into target rods for an initial 1 year irradiation at the Savannah River Plant, followed by irradiation in a HFIR (High Flux Isotopic Reactor).
After 4 months in the HFIR the targets were removed for chemical separation of the einsteinium from californium.
