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 Thulium was discovered by Per Teodor Cleve in year 1879 in Sweden. Thulium derived its name derived its name from from Thule, the ancient name for Scandinavia
