History

History
The element Dysprosium was discovered by Lecoq de Boisbaudran in year 1886 in France. Dysprosium derived its name from from the Greek dysprositos, meaning 'hard to get'
The element Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name derived its name from from Samarskite, the name of the mineral from which it was first isolated
