nostalgia

In 1688, a Swiss medical student named Johannes Hofer needed a term for a strange affliction killing Swiss mercenaries serving abroad. They were wasting away, unable to eat or sleep, consumed by longing for their Alpine homeland. Hofer coined nostalgia from Greek nostos (return home) and algos (pain, grief). It was, literally, the pain of wanting to go home.

For two centuries, nostalgia was a serious medical diagnosis. Military doctors recorded epidemics of it. Soldiers died from it. Treatments included leeches, opium, and—most effective—being sent home. The Swiss were thought particularly susceptible; some armies banned the playing of certain Alpine melodies believed to trigger fatal nostalgia attacks.

By the late 19th century, doctors stopped considering nostalgia a disease. Psychiatrists reframed it as a symptom of depression or anxiety. The word drifted from medical vocabulary into everyday speech, its meaning softening from mortal illness to wistful longing.

Today nostalgia is a marketing strategy, a political tool, and a collective mood. We have nostalgia for decades we never lived through, for products we never owned, for a past that may never have existed. The disease of homesickness became the condition of modernity.
