The story of nickel begins not in a laboratory but in the mines of medieval Germany and Scandinavia, where frustrated miners cursed an ore that looked exactly like copper but refused to yield any. They called it Kupfernickel, literally copper demon or copper Nick, after the mischievous sprites of German folklore that were blamed for everything that went wrong underground. Nick was a familiar shortening of Nikolaus, a name applied to various troublesome supernatural beings, much as English speakers used Old Nick as a name for the devil.
The ore in question was niccolite, or nickeline, a nickel arsenide mineral with a pale copper-red color that convincingly mimics copper ore. When smelted using traditional methods, it produced only a worthless, smelly slag (the arsenic content released toxic fumes), reinforcing the miners' conviction that malevolent spirits were at work. Similar frustrations gave rise to cobalt, named from Kobold, the German word for goblin, because cobalt ores similarly deceived miners and released poisonous arsenic fumes when heated.
In 1751, the Swedish mineralogist Axel Fredrik Cronstedt succeeded in isolating a previously unknown metal from the kopparnickel ore. He announced his discovery in 1754 and named the new element nickel, adopting the miners' folk name but stripping away the copper prefix. This was an unusual choice for the era. Most new elements received classical or descriptive names from Latin or Greek. Cronstedt's decision to honor the miners' vernacular preserved a piece of industrial folklore in the periodic
Nickel proved to be extraordinarily useful. It is hard, ductile, resistant to corrosion, and takes a brilliant polish. These properties made it ideal for coinage. Switzerland began using nickel in coins in 1881, and the United States followed with the five-cent piece that Americans quickly nicknamed the nickel, a name that stuck so firmly it became the official designation. Before the nickel five-cent coin, the term had briefly been applied to certain one-cent coins that contained nickel in their alloy.
The word's journey from demon to denomination reflects a broader pattern in the history of metallurgy, where folk names born from superstition and frustration become permanently embedded in scientific nomenclature. The periodic table preserves several such stories: tungsten comes from Swedish for heavy stone, bismuth may derive from a German mining term meaning white mass, and manganese traces back to Magnesia, a region in Greece associated with mysterious stones.
In modern usage, nickel has expanded well beyond chemistry and currency. To nickel-and-dime someone means to drain them through small, petty charges. A nickel defense in American football features five defensive backs. Nickel-plating describes a corrosion-resistant coating applied to metals. The Nickelodeon theater chain, and later the television
Nickel allergies are among the most common contact allergies in the world, affecting roughly ten to twenty percent of people. This has led to regulations in the European Union limiting nickel content in jewelry and other items that contact the skin. The element that miners once cursed as a demon continues to cause irritation, though of a rather more prosaic kind.
The United States nickel coin itself has an interesting relationship with its namesake metal. Modern US nickels are actually seventy-five percent copper and only twenty-five percent nickel. During World War II, nickel was needed for the war effort, so wartime nickels were struck from an alloy of copper, silver, and manganese, containing no nickel at all. A coin called the nickel that contains no nickel is a fitting irony for a metal
