• History (discovery)

      • Cerium was discovered by Wilhelm von Hisinger and Jöns Jacob Berzelius during 

the winter of 1803 in Sweden. Martin Klaproth also discovered it around the same 

time as Wilhelm von Hisinger and Jöns Jacob Berzelius in Germany. Hisinger and 

Berselius were studying a Cerite and noticed a new element in it and further 

examined it to discover Cerium.
