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 Holmium was discovered by Marc Delafontaine in year 1878 in Switzerland. Holmium derived its name derived its name from from Holmia, the New Latin name for Stockholm
