Origin & History of “nickel”

The element nickel was named in 1754 by the Swedish mineralogist Axel von Cronstedt. The word he chose was a truncated form of kupfernickel, a term formerly used by German miners for niccolite, a nickle-bearing ore. this meant literally ‘copperdemon’, an allusion probably to the fact that niccolite looks as though it contains copper, but does not. The -nickel part of the term represents a pet form of the name Nikolaus, perhaps chosen for its resemblance to German nix ‘water-sprite’. Nickel was first used for a US five-cent coin (made of a copper and nickel alloy) in the 1880s.
