Valais Monster

In the spring of 1946, livestock in the Swiss canton of Valais began turning up dead on mountain pastures, sparking a wave of panic. The Swiss press quickly dubbed the culprit the "Valais Monster" (Monstre du Valais), also called the Eischoll Wolf or the Mysterious Animal of Leuk. The name refers to one or more predators that attacked herds from April 1946 onward. Though witnesses and media reports often claimed the beast was a lynx or even a panther, the animal shot in Eischoll on 27 November 1947 turned out to be a large European wolf.

Scholars study the Valais Monster as a case study in modern rumor, revealing how people relate to large carnivores. The episode shows a strong tendency to imagine dangerous felines, fueled by fear and unreliable testimony. The wolf killed in 1947 also proves that wolves were occasionally present in the Alps at a time when the species was thought to have vanished from the region.

The name "Valais Monster" was coined by the Swiss press, and the case is also known as the "mysterious animal of Leuk." Much of the commentary came from the abbot and naturalist Ignace Mariétan, writing in his *Bulletin de la Murithienne*. Police reports and local newspapers—especially the *Nouvelliste valaisan* and the *Journal et feuille d'avis du Valais*—help fill out the story. According to Anne Bachmann, reconstructing the affair is difficult because sources disagree: Mariétan records attacks the press omits, and vice versa, with differing dates and victim counts.

The Valais Monster belongs to a tradition of "ferocious beast" rumors. Earlier cases often involved man-eating dogs or wolves, but by the 20th century, the imagined beasts were usually felines and limited to killing domestic animals. The scale of the panic can be partly explained by the prior elimination of large predators in Switzerland. Wolves had disappeared from Valais by the end of the 19th century, bears and lynxes by the early 20th. Pastoral life went undisturbed, and locals lost their knowledge of large predators, making identification and hunting difficult. According to Alexandre Scheurer, Valais residents had a "perception of fauna dominated by fear and fantasy." They feared wolves despite only one recorded human victim in the region—a child in 1637. This contrasts sharply with France, where wolves killed many people.
