Holmium was discovered by Swiss chemists Marc Delafontaine and Jacques-Louis Soret in 1878.

They noticed the aberrant spectrographic absorption bands of the then-unknown element.

Later in 1878, Per Teodor Cleve independently discovered the element while he was working on erbia earth. From the Latin word Holmia meaning Stockholm 82 From the Anglo-Saxon word "lead; Latin, plumbum" (the origin of the symbol Pb is the Latin word "plumbum" meaning "liquid silver"

Holmium is considered to be of low toxicity

Holmium has the highest magnetic strength of any naturally occurring element

Holmium is used to create the strongest artificially generated magnetic fields, when placed within high-strength magnets as a magnetic pole piece.

It is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring.

Holmium isotopes are good neutron absorbers and are used in nuclear reactor control rods.
