De Boisbaudran discovered Dysprosium in 1886.
It can be found in the minerals monazite and bastnasite.
Compounds including Dysprosium are used in lasers.
Its high melting point and neutron absorption capabilities may make Dysprosium useful in nuclear reactors.
It is named for the Greek word dysprositos, meaning hard to get at.
