History

History
The element Neodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Neodymium derived its name from from the Greek neos didymos meaning 'new twin'
The element Lanthanum was discovered by Carl Gustaf Mosander in year 1839 in Sweden. Lanthanum derived its name derived its name from from the Greek lanthanein, meaning 'to lie hidden'
