The spectral absorption band of Holmium was first noticed in 1878, but the Element itself was not discovered until a few years later by Cleve. It occurs in gadolinite and monazite. This Element has unusual magnetic properties. Holmium does not have any useful purposes in industry. Holmium is named after "Holmia", the Latin word for Stockholm. [LM] {RW}
