To understand the modern concept of "nostalgia"—which today is usually experienced as a bittersweet, sentimental longing for the past—one must look back to its origin in the late 17th century. At that time, nostalgia was not merely a fleeting emotion. It was classified as a severe, physically degenerative, and potentially fatal neurological disease, primarily observed in displaced Swiss mercenaries.
Here is a detailed explanation of how this fascinating medical diagnosis came to be, how it was understood, and why it was associated with Swiss soldiers.
1. The Origin of the Diagnosis
The term "nostalgia" was coined in 1688 by Johannes Hofer, a 19-year-old Swiss medical student at the University of Basel. He created the word by combining the Greek roots nostos (return home) and algos (pain or longing).
Hofer invented the medical term to describe a phenomenon already known colloquially in Swiss-German as Heimweh (homesickness) or in French as maladie du pays. Hofer observed that young Swiss people living abroad—particularly students, domestic workers, and soldiers—were falling physically ill from an obsessive desire to return to their alpine homeland.
2. The Demographic: Swiss Mercenaries
In the 17th century, the Swiss economy relied heavily on the export of its young men as mercenaries. Renowned for their discipline and ferocity, Swiss pikemen and guards were hired by foreign monarchs across Europe, including the Kings of France and the Pope.
These young men were taken from the pristine, high-altitude, tight-knit communities of the Alps and thrust into the chaotic, disease-ridden, and brutal lowlands of foreign battlefields. The stark contrast between their peaceful homes and the horrors of 17th-century warfare, combined with intense cultural isolation, created the perfect storm for severe psychological distress.
The trigger for this distress was famously specific. It was widely reported that hearing the Kuhreihen (or Ranz des Vaches)—a traditional alpine melody played on the alphorn by Swiss herdsmen to call cattle—would cause Swiss mercenaries to break down weeping, fall into despair, or desert the army. The association was so strong that playing or singing the Kuhreihen was punishable by death in some French mercenary regiments.
3. The Medical Classification: A Neurological Disease
Unlike modern psychology, which would classify severe homesickness as a form of depression or adjustment disorder, 17th-century medicine was heavily influenced by the early understanding of neurology and the ancient theory of bodily humors.
Hofer did not view nostalgia as a mere mood; he classified it as a "disease of the imagination" with a distinct neurological pathology. According to the medical science of the day, human physiology was driven by "animal spirits" flowing through nerve channels. Hofer theorized that continuous, obsessive thoughts about home caused these animal spirits to become trapped or congested in the middle lobe of the brain.
Because the "life force" was stuck continuously replaying memories of the Swiss Alps, the rest of the body was deprived of vital energy. This neurological blockage manifested in severe, compounding physical symptoms, including: * Profound lethargy and melancholia * Loss of appetite and subsequent malnutrition (cachexia) * Irregular heartbeat and palpitations * Fainting spells * High fever and brain inflammation * Hallucinations (seeing the faces of family members or hearing alpine sounds)
If the condition went untreated, it was believed that the patient would literally waste away and die, either through bodily failure, starvation, or suicide.
4. Treatments and "Cures"
Because nostalgia was viewed as a somatic (physical) disease, doctors treated it with standard 17th-century physical interventions. Treatments included bloodletting, the application of leeches, purging the stomach, and administering opium to calm the mind.
However, doctors and military commanders quickly realized that these physical treatments were mostly useless. There were only two ways to address the disease: 1. Terror and Discipline: Some military commanders tried to beat or frighten the disease out of their troops. In one infamous instance, a Russian general dealing with an outbreak of nostalgia among troops ordered that the first soldier to fall ill be buried alive, which supposedly scared the rest of the regiment out of their symptoms. 2. The Ultimate Cure (Going Home): Hofer and other physicians noted that the only reliable cure for nostalgia was the promise of returning home. Merely telling a dying mercenary that he had been granted leave, or placing him on a carriage headed toward the mountains, could cause a miraculous, almost instantaneous physical recovery.
5. Evolution of the Concept
Nostalgia remained a recognizable medical diagnosis well into the 19th century. During the American Civil War, military doctors recorded thousands of cases of nostalgia among soldiers, many of whom died from "wasting away" in camp.
It wasn't until the late 19th and early 20th centuries, with the birth of modern psychiatry and psychoanalysis, that nostalgia lost its status as a fatal neurological disease. It was reclassified first as a form of melancholia (depression) and later entirely decoupled from geography. By the mid-20th century, nostalgia shifted from a spatial longing (wanting to return to a place) to a temporal longing (wanting to return to a time), evolving into the bittersweet sentiment we recognize today.
