Loyen

Loyen is the expedition scientist whose investigations at Gela Alta connect the discovery of a meteorite to a lethal parasitic infection in human beings. Across expeditions in the 1930s, 1966, and 1991, he moves from taking Inuit accounts seriously to conducting research that transforms an Arctic worm’s relationship with its hosts. His work supplies the scientific history behind the novel’s central crisis, while its human cost exposes the distance between discovering how a pathogen works and deciding what its knowledge permits.

Identity and Expeditions

Loyen first came to Gela Alta in the 1930s with a German expedition tasked with preliminary work for an airport on a narrow strip of flat coast. The party brought Thule Inuit with it; West Greenlanders declined to join because the island had a bad reputation. Like Knud Rasmussen before him, Loyen took Inuit stories seriously, and this approach led him to the meteorite. The episode establishes both the practical setting of his research and a method of inquiry that begins by listening to local knowledge rather than dismissing it.

He returned in 1966 with Ving and Andreas Fine Licht. This time the expedition had located the stone and constructed a permanent passageway to it, but the party had not solved the technical problems needed to complete its plan. Loyen opposed using blowtorches to cut the meteorite. The team instead prepared a saw: a hardened steel band running across rollers, photographed as part of the expedition’s equipment. The distinction matters because the project was not merely speculative; the researchers had progressed to planning how to remove a piece of the stone.

Loyen also returned in 1991, when the expedition that included Smilla was forced to go home. These successive visits make Gela Alta less a single discovery site than a long-running scientific project, carried across decades and repeatedly interrupted by obstacles that the surviving account only partly explains.

The 1966 Deaths and the First Discovery

The 1966 expedition’s work changed abruptly when the Inuit participants died. They had been preparing to position the saw when the deaths occurred, almost simultaneously and within an hour of one another, forty-eight hours after the first dive. According to Tørk’s later account, Loyen recognized that the project had failed and time was running out. He improvised an accident, but did not destroy the bodies; suspecting that something was wrong, he performed autopsies once the party reached Nuuk.

The autopsies disclosed an unexpected finding. The bodies contained the Arctic worm, a parasite ordinarily associated with large sea mammals, not people. Loyen had not set out to investigate a human infection: X-rays taken at the last minute to identify the bodies helped reveal it. His discovery therefore begins in the aftermath of a failed expedition, when an effort to explain the deaths opens a much larger biological question.

The research room at Gela Alta preserves a material trace of the earlier investigation. Among the ice-covered equipment are microscopes, chromatographs, crystallization jars, an incubator, and an electrophoresis apparatus. Tørk identifies the electrophoresis device as equipment Loyen brought in 1966, when the team still thought it might be dealing with some form of organic life. The instruments show how the expedition’s inquiry developed: the meteorite and the surrounding environment had become part of a laboratory problem, even before the researchers understood what they were looking at.

From Ecological Cycle to Human Infection

Tørk explains the Arctic worm as a parasite whose ordinary life cycle depends on particular hosts and environmental pathways. Its larvae enter water fleas, including Cyclops marinus; an infected flea can then be swallowed by a larger mammal, where the parasite matures. In sea mammals, the worm’s development is slow, and its established hosts include whales, seals, and dolphins, with walruses also mentioned as occasional hosts. The cycle’s limits help explain why it had not simply spread everywhere: the parasite depended on suitable animals and on the chance of reaching them.

The discovery in human remains confronted Loyen with the exception to that pattern. People, including Inuit communities who regularly ate infected meat, were not supposed to be viable hosts. The human immune system ordinarily recognized the larvae as foreign and destroyed them. Loyen therefore faced a question that his autopsies could not answer by themselves: not only how the worm had entered the dead men, but how it had overcome a barrier that had previously kept it from adapting to humans.

Tørk says Loyen had brought home samples from the water around the stone. The lake was fed not only by meltwater but also by a higher lake on the surface, with bird life, trout, and several kinds of water fleas; all the samples Loyen took were infected. Unable to answer why the human infections had occurred, Loyen redirected his inquiry toward how they could occur. He decided to graft the larva onto living human tissue. The account marks a consequential transition from observing an unexpected infection to deliberately testing its capacity to adapt.

According to Tørk, that process took twenty-five years. Loyen found that the larva could adapt to the human immune system by penetrating the mouth’s open mucous membranes and forming a protective layer from the person’s own proteins. In this camouflage, the parasite was mistaken for part of the human body and escaped immune attack. Its development in people was also much faster than in sea mammals: growth and the stages that could take months in a marine host now took days. The research thus altered the significance of the original discovery. The worm was no longer merely an unusual finding in the 1966 bodies; it had become an organism capable of completing its cycle in a human host.

Experiments, Consequences, and Significance

Tørk’s account extends Loyen’s research beyond the original human cases. He says that Loyen grafted the worms onto two Greenlanders with AIDS, had them flown to Denmark, and admitted them to small private hospitals. The researchers followed the worms’ progress with ultrasound scanners. This episode makes the clinical subjects part of the history of experimentation, not incidental witnesses to it; the account presents Loyen’s work as proceeding through intervention in living people as well as examination of the dead.

The research also changes the parasite’s ecological limits. Tørk says Verlaine grafted larvae onto every fish the group could obtain—saltwater and freshwater, large and small, at varying temperatures—and that the parasite adapted to each. He concludes that one major restraint on its spread, the limitation of hosts capable of transmitting it, is gone. The possibility of worldwide dispersal remains conditioned by the parasite’s slow development in sea mammals and the need for enough human beings to accelerate its cycle, but the host barrier that once contained it has been breached.

Loyen’s role is therefore neither simply that of the first discoverer nor that of a detached observer. His initial expedition depends on Inuit knowledge; the deaths of the 1966 party redirect his work toward a human infection; and the research that follows takes the parasite beyond its former biological limits. The novel makes that progression part of its larger account of scientific ambition and ecological balance: identifying a mechanism does not settle the question of what should be done with it, and a discovery made in a remote Arctic environment can acquire consequences far beyond the expedition that uncovered it.
