History

History
The element Manganese was discovered by Torbern Olof Bergman in year 1774 in Sweden. Manganese derived its name from corrupted from magnesia negra, see Magnesium
The element Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name derived its name from from the Greek osmè, meaning 'smell'
