One of the two infamous figures central to the creation of the term "Stockholm syndrome," Clark Oloffson, has passed away at 78 after battling a prolonged illness, as confirmed by his family through Dagens ETC. Oloffson gained global recognition in 1973 when he participated in a six-day hostage situation during a bank robbery in Stockholm. During this period, the captives began forming emotional bonds with Oloffson and his accomplice, which resulted in them defending the criminals and displaying aggression towards the police trying to negotiate their release.

This peculiar phenomenon eventually birthed the term "Stockholm syndrome," describing a psychological response in kidnappers’ victims. The bank heist was initially orchestrated by Jan-Erik Olsson, who took three women and a man as hostages and insisted that Oloffson be released from prison to assist in the robbery. Authorities acquiesced to his demands and allowed Oloffson to join the scene, which was heavily surrounded by law enforcement.

Years later, Oloffson claimed in an interview with Aftonbladet that he had been offered a chance to act as a mediator in exchange for a lighter sentence, although he felt the deal was not honored by the authorities. Throughout the crisis, Oloffson convinced one of the hostages, Kristin Enmark, to engage with top officials on behalf of the captors, appealing for their release alongside the criminals, stating, “I completely trust Clark and the robber... They haven't done a thing to us.” Enmark later recounted feeling a bizarre sense of loyalty toward her captors and even feared for their safety should police intervene.

The standoff concluded after six days with a dramatic police operation that involved breaking through the roof and deploying tear gas. Intriguingly, while they were freed, the hostages initially hesitated to escape out of concern for Oloffson and Olsson’s safety. They later chose not to incriminate the criminals by testifying against them. Whether Stockholm syndrome is a genuine psychiatric phenomenon has long been debated among experts in psychology and criminology.

The term itself was popularized by criminologist and psychiatrist Nils Bejerot, following the incident, to describe the surprising emotional attachment displayed by hostages toward their captors. This concept gained further media attention the following year when Patty Hearst was abducted by radicals. In a 2021 interview on the BBC's Sideways podcast, Enmark contested the notion of Stockholm syndrome, asserting it shifts blame onto victims, emphasizing the survival instincts that motivated her actions.

Oloffson, known for a pattern of repeated offenses, spent substantial periods incarcerated and was last released in 2018 after a drug-related conviction in Belgium. His life was later dramatized in the 2022 Netflix series titled Clark, starring actor Bill Skarsgård.
