The Surgeon's Photograph
DebunkedSummary
The Surgeon's Photograph, published in the Daily Mail on 21 April 1934, showed a small head and long neck rising from Loch Ness and became the most famous image of its monster. In 1994 the researchers David Martin and Alastair Boyd made public the account of Christian Spurling, who said the monster was a model on a toy submarine, made for his stepfather, Marmaduke Wetherell.
Wetherell had been embarrassed a few months before the photograph, when the footprints he had found for the same newspaper turned out to have been made with a hippopotamus foot.
What is documented
The footprints. In December 1933 the Daily Mail engaged Marmaduke Wetherell, "an actor, film director, and big-game hunter" in NOVA's description, to find the creature. Within days he reported the tracks of a large four-toed animal, and before Christmas he sent plaster casts to the Natural History Museum in London. In early January 1934 the museum's experts found that the prints had been made with a stuffed hippopotamus foot, of the kind used as the base of an umbrella stand or ashtray. Who made them is disputed. NOVA says it was not clear whether Wetherell was the perpetrator or a victim; the Loch Ness Project says he used one of his own big-game trophies.
The photograph. On 21 April 1934 the Daily Mail published a photograph of a small head and neck above the water, attributed to Robert Kenneth Wilson, a London surgeon. Wilson said he had taken it early in the morning of 19 April while driving along the northern shore. For decades it was treated as the best evidence for the monster. The version given to the press was cropped; the full frame shows how small the object is against the loch.
The doubts. In 1984 Stewart Campbell, writing in the British Journal of Photography, concluded that the object could have been two or three feet long at most, probably an otter or a bird, and suggested that Wilson knew it. Alastair Boyd, a researcher who believed in the monster, said he had suspected a hoax because "the water texture in the surgeon's photo indicates to me that we're looking at a small object". According to the Loch Ness Project, Wilson himself had admitted as much at least twice, and writers on the monster had ignored him.
The confession. Boyd's investigation led to Christian Spurling, Wetherell's stepson. Before his death at the age of 90, Spurling said that Wetherell had asked him to make a convincing serpent model, and that the model, which NOVA describes as "a one-foot plastic neck" fixed to a toy submarine, was photographed on Loch Ness. The picture was then passed to Wilson, whose part was to be a credible front man. Wetherell's son later remembered his father saying, "We'll give them their monster."
The exposure. The story broke in 1994. The Loch Ness Project, whose member David Martin worked on it with Boyd and the Loch Ness Centre, dates it to April of that year. Martin and Boyd set out the case in their 1999 book, Nessie: The Surgeon's Photograph Exposed.
Leading explanations
A model on a toy submarine, fronted by Wilson. Established by the account of one of its makers, and consistent with the photograph. Spurling described how it was made and how it reached Wilson. The full frame shows a small object, as Campbell had calculated from the image a decade earlier.
A living animal. Rejected. The object is too small for the animal the photograph was taken to show, and one of the men who made it described the model.
An otter or a bird (Campbell, 1984). Superseded. Campbell's measurement of the object's size stands. His identification of it does not: it was a model.
What the popular version gets wrong
"It shows a large animal with a long neck." It shows a small object that the crop made look large. Campbell put it at two or three feet at most, and the neck of Spurling's model was about a foot long.
"It fooled everyone for sixty years." It fooled many people, but not everyone. Sceptics doubted it for years, Campbell published his measurement in 1984, and Boyd suspected it from the texture of the water. According to the Loch Ness Project, the surgeon himself had admitted as much at least twice.
"A respected surgeon had no reason to lie." In Spurling's account the surgeon's respectability was the point: his job was to be a credible front man for a photograph he had not taken.
Current status
Debunked. The photograph shows a model, made by Wetherell's stepson and fronted by a surgeon. The account comes from one of the men who made it, and it fits the image, whose full frame shows a small object. The exposure came from a researcher who believed in the monster. Only evidence that Spurling's account was itself invented would reopen the case.
