The Minnesota Iceman

A refrigerated coffin with a plate-glass lid held a block of cloudy ice with a hairy male body inside it. The published descriptions agree closely. The body lay on its back, right arm across the lower abdomen, left arm crooked above the head, knees slightly bent, about six feet long, coarse dark hair everywhere but the face, palms, and soles. The face was pug-like, the nose tip turned up over wide flaring nostrils. The left eyeball was out of its socket, lying on the left cheek. The left forearm was fractured about midway along its length, the flesh gaping at the break. The coffin traveled on a semi trailer to fairs and stock shows behind display boards reading "the Near-Man, the Siberskoye Creature," at thirty-five cents a look. DOCUMENTED

That an exhibit like this existed, and that qualified people examined and described it, is settled. Almost everything else was said by one man, or is still argued about.

How they got there

On December 12, 1968, the Society for the Investigation of the Unexplained, whose administrative director was the naturalist and Argosy science editor Ivan T. Sanderson, took a phone call from Terry Cullen of Milwaukee, Wisconsin. Sanderson described Cullen, then a stranger to him, as a zoologist running a commercial herpetology business and the discoverer of several new iguanid lizard species in the Caribbean. Cullen had seen the exhibit at the International Livestock Exposition's annual fair in Chicago, which ran November 28 to December 7. Two Chicago members of the society confirmed the thing existed.

Bernard Heuvelmans, the Belgian zoologist who had launched cryptozoology with Sur la piste des bêtes ignorées (1955), was staying at Sanderson's New Jersey property. Heuvelmans was a scientific collaborator at the Institut royal des Sciences naturelles de Belgique, which matters later, because that is where he published. The two drove to Frank D. Hansen's farm near Rollingstone, outside Winona, Minnesota, and on December 17, 1968 they began looking. They stayed two days.

Hansen told it differently in 1995: Sanderson phoned about an abominable snowman sighting in Wisconsin, turned up unannounced in a blizzard with Heuvelmans, and was told he could not see the exhibit at all. Napier, drawing on Sanderson, says Hansen received them in a friendly manner and gave unrestricted access. CONTESTED

Conditions were bad and everyone said so. The trailer was cramped, and Sanderson lay face down on the plate-glass lid to make his scale drawings. They could not open the case, touch the specimen, or take a sample. Sanderson wrote that the ice was "more than half opaque" and the body sunk "about two feet below the glass cover of its container."

The smell is the part everyone remembers. In Argosy for May 1969, in an article titled "The Missing Link?", Sanderson wrote of "the appalling stench of rotting flesh exuding from a point in the insulation of the coffin." Hansen later supplied a mechanism: Heuvelmans laid a 150-watt bulb on the freezing glass to light the face for photographs, the glass shattered into cracks without falling apart, and the odor came out. Nobody bottled the smell, cultured it, or measured it. It rests entirely on the accounts of the people in the trailer. ALLEGED

What each man actually published

Heuvelmans moved fast. His twenty-four-page paper ran in the Bulletin de l'Institut royal des Sciences naturelles de Belgique, volume 45, number 4, describing the specimen as the fresh corpse of a Neanderthal-type hominid and naming it Homo pongoides, "ape-like man." Sources give the publication date as February 10, 1969, though that specific date traces to a single secondary source. DOCUMENTED

Two details usually get dropped. His own title qualified the name "(sp. seu subsp. nov.)," species or new subspecies, hedging the rank even as Sanderson read the paper as claiming full specific rank. And the journal belonged to the institute where he held his position.

Sanderson's technical paper ran the same year in the Italian journal Genus, volume 25. It is stranger than its reputation, and retellings leave out both interesting parts.

First, Sanderson printed the case against his own exhibit. Two Hollywood model-making companies, he reported, "have been traced, and individual model-makers working for both have stated that they made copies with wax or latex and using hair from bears." Hansen, whom Sanderson called "the caretaker," had told them in January 1969 that such a model had been made in April 1967, and here is the qualifier the retellings cut: because the owner of the original was worried about its safety. In Hansen's framing the model was a copy of something real, not a confession. Sanderson then sketched how the thing might be built anyway, "starting with the skin of a large male, pale-skinned chimpanzee, using a human skull, glovemakers wood racks for the hands, and so forth."

Second, he took his name off the species. Sanderson had proposed the epithet pongoides himself, but as a tentative subspecies label, not a new species of Homo. When Heuvelmans elevated it, Sanderson wrote: "I am therefore officially disassociating my name from that given in Heuvelmans' paper." Nothing should be named before it is physically obtained, he argued, and he was not convinced the object was neanderthaloid "or even a member of the genus Homo as presently constituted."

He did not conclude it was a model. His stated conclusion was "that the specimen we inspected was that of a genuine corpse as opposed to a composite or a construction, and that it is some form of primate." The popular version has Sanderson coming to his senses in Genus. In print, he never did.

The Smithsonian and the FBI

Sanderson went to the law first, contacting the FBI's New Jersey office in January 1969 and, in Napier's words, receiving "a dusty answer." One secondary source dates that contact to January 18. On February 3, 1969, Sanderson telephoned John Napier, who described himself as curator of the primate collections at the Smithsonian. Napier took it to Secretary S. Dillon Ripley, who agreed the Institution should take an official interest.

The Smithsonian then asked to inspect and x-ray the specimen, reportedly on March 13, 1969. Hansen replied that it was no longer in his hands, its anonymous owner having removed it, and that the coming season's exhibit would "in many respects resemble" the original. With Heuvelmans's paper now certifying the body in print as human and shot, Ripley wrote to J. Edgar Hoover asking the FBI to trace it. Hoover replied that no violation of federal law had been proved, so the Bureau had no power to act. Hansen's response to being investigated was to add the words "Investigated by the F.B.I." to his display boards.

Napier's arithmetic

Napier never saw the exhibit, which is routinely gotten wrong. He wrote that his role was "distinctly that of 'voices off.'" What he did instead, in Bigfoot: The Yeti and Sasquatch in Myth and Reality (1972), was measure Sanderson's scale drawings, correlated against Heuvelmans's photographs.

The obvious weakness is one Napier stated himself: the drawings were, as Sanderson admitted, "drawn under considerable difficulties." Every number above is a measurement of a drawing of an object nobody could touch.

Sanderson had also recorded that the hairs were agouti, banded light and dark like a squirrel's. Agouti banding is common among monkeys, but Napier wrote that "at the higher levels of primate evolution," among the apes and man, "it is completely unknown." He called agouti hair on the Iceman "a zoological improbability of the highest order," and concluded that if Sanderson's observation held, "the likelihood that the Iceman is an artifact, a man-made object, is high."

His argument was never that such an animal is impossible. It was that this object combined "the worst features of apes and man and none of the best": a foot adapted neither for climbing like a chimpanzee's nor for walking flat like a man's, hands that were "a ridiculous compromise" between the two. The Iceman "does not match up to the blueprint of any known primate or, indeed, any known animal." Then the sentence skeptics leave out: "This does not mean that the Iceman cannot exist, it simply makes it just that much more improbable."

On Napier's advice the Smithsonian issued a press release withdrawing its interest, which promptly produced rumors that it was sitting on a missing link. Napier repeated those as rumors and named no source.

The switch

Before reopening in a St. Paul shopping precinct, Hansen held a press conference at his place near Winona. The Rochester Post-Bulletin's Gordon Yeager, writing in the issue of April 21, 1969, reported Hansen's line that the thing was man-made, an illusion, and not his property anyway.

In Yeager's color photographs the mouth is agape with at least four teeth visible, where Heuvelmans had recorded a mouth "slightly open and one can see a yellowish tooth." The left big toe, firmly apposed to its neighbors in the original, was now widely separated. With a Time-Life film shot at Grand Rapids, Michigan, Napier held that these made it "quite clear" the creature was not identical to the one examined in December 1968. DOCUMENTED

Sanderson said categorically that this was not the object he and Heuvelmans had examined. He put it in the Genus paper too, writing that the specimen "has been removed from the place where we saw it, and hidden, while a substitute model has been installed."

Hansen agreed, in 1995, that a switch happened, and said he arranged it: the owner sent a refrigerated truck, "we made the big switch," the original went back to California, and Hansen called a news conference to present what remained as a Hollywood fabrication.

Napier accepted the non-identity and drew a different conclusion from it. His reconstruction was that there had only ever been one model, defrosted, altered, and refrozen while Hansen was away between March 25 and April 12, 1969. He was blunt about its status: "there is still no certainty that the 'original' was any more 'real' than the substitute model," and "I can offer no kind of proof for my suggestions." CONTESTED

Heuvelmans reached the opposite conclusion, and is quoted as writing that after comparing color slides of the 1969 exhibit against his own photographs, "I had to agree with the evidence: it was the same and only specimen." The quotation circulates through Brian Dunning's 2017 Skeptoid episode with no original citation. It cannot come from the February 1969 paper, since it describes slides of an exhibit that did not yet exist. Treat it as secondhand until someone produces the source. Dunning's same episode also has Sanderson concluding the two exhibits were identical, which is the reverse of what Napier and Sanderson himself wrote.

Hansen's accounts

His story changed repeatedly, and the changes are checkable.

The Saga version is not a straightforward confession, and summarizing it as "he admitted he made it" gets it backwards. In that account Hansen shot a real creature in 1960, had a Hollywood model built in early 1967, exhibited the model through the 1967 season so that carnival people would accept the show as bogus, and then in March 1968 melted both down and swapped the real specimen in for the 1968 season.

The owner was never produced. Hansen described him to the Sunday Times only as a wealthy West Coast man connected with the movie business, whose pleasure "is to have something rare, something that other people don't have." Smaller details drift. In Saga the exhibit debuts at Los Banos, California on May 3, 1967; in Fortean Times the first showing is Chico. In 1995 Hansen said Napier or another Smithsonian man had seen the exhibit in Canada and caused his trouble at the border, and that he telephoned Senator Walter Mondale for help. Napier's account says he never saw it at all. Border officials at Pembina, North Dakota did refuse the exhibit passage from Canada in July 1969 unless Hansen proved he was not carrying a corpse.

Hansen closed the Saga piece this way: "There will surely be skeptics that will brand this story a complete fabrication. Possibly it is, I am not under oath and, should the situation dictate, I will deny every word of it." The magazine ran it under the heading Fact or Fiction.

Who built it

Every Hollywood name attached to this object comes, in the first instance, from Hansen, and in Saga they are the people who built a copy, not the body. He wrote that in January 1967 he took sketches to Hollywood and consulted Bud Westmore, director of makeup at Universal, who quoted up to $20,000 and declined the job; that a Los Angeles County Museum staffer referred him to Howard Ball, an independent artist then making life-size fiberglass elephants for the La Brea tar pits, whom he engaged to sculpt and mold the figure; and that the makeup artist John Chambers pointed him to a small Los Angeles wax studio, where Pete and Betty Corral implanted each hair individually with an open-end needle. ALLEGED

One thread is partly independent of Hansen, and it is weaker than it is usually made to sound. George Berklacy of the Smithsonian's public relations office telephoned his way to a West Coast commercial organization that claimed it had made the Iceman for Hansen out of latex rubber and hair in April 1967, and the name Pete Corrall came up in that call, before Hansen published it in Saga, where it is spelled Corral. Napier recorded two caveats that retellings drop: "there is no proof that the story Berklacy was given was true," and Sanderson told him at least two other organizations claimed the same credit. An unnamed firm's phone claim, contradicted by other claimants, is not proof of manufacture. CONTESTED

What is documented is what the Smithsonian printed. Its house paper, the Smithsonian Torch, reported in June 1969 that the Iceman was "Made from latex rubber and hair by a group of exhibits specialists on the West Coast" at a cost of $3,500. The Institution's public statement said it was "satisfied that the creation is simply a carnival exhibit made of latex rubber and hair." DOCUMENTED

The claim that a Disney Imagineer built it traces to the 2013 eBay listing, which said only that the figure was "thought" to have been crafted by one. No name, no source. ALLEGED

Where it went

Hansen toured the exhibit into the 1970s, then told Fortean Times he pulled the plug, let it thaw, and shipped it to California. He dropped out of the story. A Cryptomundo post of April 9, 2006, filed under Obituaries, refers to "the late Frank Hansen." No published death date was found for this entry.

In February 2013 an eBay listing under the slug "Genuine-Minnesota-Iceman-Sideshow-Bigfoot-1960s," from a seller using the handle hauntarmada, offered the figure with its roughly 4-by-4-by-8-foot freezer housing, upwards of 1,000 pounds, plus the original signage, at a $20,000 Buy It Now price. The listing called it "the actual sideshow gaff billed as 'The Minnesota Iceman' by Frank Hansen in the 1960's" and "a one of a kind hoax that was fabricated by a mid-20th century showman." Craig Woolheater reported that the auction ended with a buyer offering less than the asking price. The actual sale price has not been published; $20,000 was what was asked, not what was paid.

The buyer was Steve Busti of the Museum of the Weird in Austin, Texas. The haul from Minnesota was filmed for season four of A&E's Shipping Wars, in an episode titled "Crypto-Prank-ology." Dunning notes that in the aired footage much of the ice had melted by the time the figure reached Austin, leaving the face and raised arm plainly visible. It has been on display there since mid-2013. Darren Naish, working from published images, writes that it "certainly looks identical to the specimen discussed and illustrated by Heuvelmans and Sanderson."

What the case is actually about

Homo pongoides rests on no specimen in any collection. It never became a valid taxon, and the trait list attached to it has no anatomical support. DEBUNKED

The damage ran past the name. As Naish has documented, wildman reports gathered from the Caucasus to Mongolia by Boris Porchnev, Dmitri Bayanov and Marie-Jeanne Koffman were later read as matching pongoides, as were more than twenty reports of the bar-manu collected in northern Pakistan by the herpetologist Jordi Magraner. Helmut Loofs-Wissowa argued in 1994 that figures in ancient art matched it too. If the template was a rubber model, every one of those matches was manufactured by the person doing the matching.

The useful lesson is narrower than "experts were fooled." Heuvelmans and Sanderson worked under conditions that guaranteed failure: an object they could not touch, in ice they could not see through, held by a man with a commercial stake in the answer, on a two-day visit, with no sample and no way to get one. One of them published a binomial eight weeks later. Napier, who never saw the thing and said so, reached a defensible position in about five months by measuring their drawings and stating plainly what the numbers ruled out, what they did not, and where his own reconstruction was guesswork. That is the difference worth taking from this case.
