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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
