History and Discovery. Nickel's discovery can be traced back to 1751 when Axel Fredrik Cronstedt isolated the metal from a copper ore that deceived miners, earning the name "kupfernickel" or "false copper.". The isolation of nickel marked a significant milestone in the field of chemistry and set the stage for its subsequent applications.
