Kupfernickel

The English word nickel comes from German Kupfernickel, a compound of Kupfer (copper) and Nickel (a shortened form of Nikolaus, used in German as a familiar name for the devil — 'Old Nick' in English). The full compound means 'copper-devil' or 'devil's copper,' and it was the miners' name for an ore (what we now call nickel arsenide, NiAs) that looked promisingly red and copper-like but yielded no copper when smelted, instead releasing toxic arsenic fumes. The German tradition of naming problematic ores after goblins and devils was well established — cobalt had already been named for the Kobold mine-goblin — and the copper-colored ore that cheated miners out of expected copper was naturally attributed to Old Nick's mischief. The name Nickel as a personal name derives from the Greek Nikolaos (victory-people), but in German folk usage Nickel became a familiar nickname for the devil, a usage parallel to the English 'Old Nick' or 'Old Scratch.'

The history of nickel ore before the element was isolated is a history of frustration and accidental discovery. Swedish and Norwegian miners had encountered nickel-bearing ore for centuries in the copper and silver mines of Scandinavia. The bright copper color of nickel arsenide (NiAs) made it appear valuable; its failure to yield copper in the furnace, combined with the toxic arsenic fumes it released, made it a source of both disappointment and occupational illness. The Swedish chemist Axel Fredrik Cronstedt isolated nickel as a distinct metallic element in 1751 from a sample of niccolite (nickel arsenide) from a mine in Hälsingland, Sweden. Cronstedt retained the German name Kupfernickel for the ore but named the element simply Nickel — stripping the 'copper' prefix and keeping the devil's name. The decision to keep the supernatural epithet while discarding the mineral description was pragmatic — it distinguished the new element from copper — but it permanently embedded a German folk superstition into the international scientific nomenclature.

Nickel's material properties make it one of the most important industrial metals of the modern era, despite being entirely unknown as a pure metal before the eighteenth century. It is corrosion-resistant, hard, and magnetic, and its alloys form the basis of stainless steel (nickel combined with chromium and iron), superalloys for jet engines, and the steel used in modern armor. The five-cent American coin called a 'nickel' — introduced in 1866 — is composed of 75% copper and 25% nickel, in an ironic reversal of the original Kupfernickel problem: the devil's copper, which frustrated miners by containing no copper, is now used in an alloy with copper to make the coin that bears the element's name. The coinage use of 'nickel' for the five-cent piece is an Americanism that has given the element's name a wider popular currency than most metallic elements achieve.

The connection between nickel and the devil's name preserves an older European tradition of demonizing the unfamiliar and uncooperative in nature. Before the systematic chemistry of the eighteenth century, ore behavior that could not be explained by the known properties of known metals was attributed to supernatural interference. Miners who found ores that behaved unexpectedly — yielding no metal, poisoning workers, exploding in furnaces — were not simply ignorant; they were working at the frontier of empirical knowledge without the theoretical framework to understand what was happening at the atomic level. The goblins and devils they blamed were imaginative placeholders for chemical processes not yet understood. When Cronstedt and Brandt replaced the goblin names with element names on the periodic table, they did not simply correct a mistake; they translated a tradition of noticing real anomalies — the toxicity, the deceptive appearance, the smelting failure — into a different explanatory framework.
