History

History
The element Cerium was discovered by Martin Heinrich Klaproth in year 1803 in Germany and Sweden. Cerium derived its name from from the then recently discovered asteroid Ceres, considered a planet at the time
The element Neodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Neodymium derived its name derived its name from from the Greek neos didymos meaning 'new twin'
