What happened
The modern Loch Ness story begins in 1933, when a new road along the northern shore opened the loch to motorists. In April of that year a hotel manager, Aldie Mackay, reported a large creature rolling in the water, and the Inverness Courier printed her account on May 2. In July George Spicer and his wife described a long-necked animal crossing the road in front of their car, and by autumn newspapers across Britain were sending reporters north. The Daily Mail went further and hired Marmaduke Wetherell, a film-maker and self-described big-game hunter, to find the animal. In December 1933 he announced that he had found its footprints on the shore. The Natural History Museum examined casts and reported that they had been made with a dried hippopotamus foot. Wetherell was ridiculed and the paper dropped him.
Four months later the Mail had a triumph. On April 21, 1934, it published a photograph showing a slender neck and small head rising from rippled water. The picture had been supplied by Robert Kenneth Wilson, a London gynecologist, who said he had taken it on April 19 while stopping on the shore road and had noticed something moving in the loch. Wilson asked not to be named, and so the picture became known as the surgeon’s photograph. For the next sixty years it was the single most reproduced image of the monster and the one most often cited as proof.
The investigation
Doubts were raised early by people who noticed how small the ripples were relative to the object. In 1984 Stewart Campbell, writing in the British Journal of Photography, analyzed the wave pattern and concluded that the object could only have been two or three feet long, consistent with an otter or a diving bird. The version everyone knew had also been cropped tightly around the neck; the uncropped print, which Loch Ness researcher Alastair Boyd rediscovered in the late 1980s, shows the far shore and makes the object look much smaller.
The decisive thread was a newspaper clipping. Boyd’s colleague David Martin found a Sunday Telegraph article from December 7, 1975, in which Wetherell’s son Ian said the photograph had been faked. Boyd noticed that Ian’s account mentioned Maurice Chambers, a friend whom Wilson had said he was visiting, and that it described scenery visible only in the uncropped print, which had been published just once, in 1934. The two men traced Ian Wetherell’s stepbrother, Christian Spurling, then in his nineties and in poor health, to southern England. In 1993, shortly before his death, Spurling told them that Marmaduke Wetherell had asked him to make a monster. He had built a head and neck from plastic wood on the conning tower of a toy submarine; the Wetherells had floated and photographed it in a quiet bay; and Chambers had arranged for the respectable Wilson to have the plates developed and present the picture as his own. The motive, Spurling said, was revenge on the Daily Mail for the hippo-foot humiliation. The story was published in 1994.
The explanations
The confession has not been accepted by everyone. The journalist Richard Smith questioned whether a 1930s toy submarine could carry the model as described and asked why Boyd waited until after Spurling’s death to publish. Writers including Karl Shuker and Henry Bauer have noted inconsistencies in the retellings, and some believers hold that the confession is itself the hoax. Against that stands the convergence of independent evidence: a fake was alleged in print in 1975, before Boyd’s investigation; the uncropped print matches Ian Wetherell’s description; the photographic analysis shows a small object; and the man who claimed to have built the model named the people, the place and the motive. The zoologist Darren Naish, reviewing the evidence in 2013, found the case for a hoax convincing.
Where it stands
The surgeon’s photograph is a hoax. That verdict does not settle the broader question of Loch Ness, which rests on decades of eyewitness reports, a handful of ambiguous photographs and films, and a series of sonar and biological surveys that have found nothing conclusive. It does mean that the one image most people picture when they hear the name Nessie was a model about a foot high, built by a man who wanted to get even with a newspaper.
