History

History
The element Iridium was discovered by Smithson Tennant in year 1803 in France and United Kingdom. Iridium derived its name from from Iris, the Greek goddess of the rainbow
The element Gadolinium was discovered by Jean Charles Galissard de Marignac in year 1880 in Switzerland. Gadolinium derived its name derived its name from from Johan Gadolin, chemist, physicist and mineralogist
