The Loch Ness Monster and the Surgeon's Photograph
The Loch Ness Monster is among the most famous legends of the twentieth century. A deep, cold lake in the Scottish Highlands, a long-necked creature, and a famous photograph make a powerful combination. Looking carefully at the history shows how the legend grew, how the key photo was faked, and what modern science can say about the loch.
The loch
Loch Ness is a long, narrow freshwater lake in the Highlands, about 23 miles long and very deep, with dark, peat-stained water that makes it almost impossible to see more than a few feet. Those conditions help explain why sightings are hard to confirm.
Stories of a creature in the area are old. A seventh-century biography of Saint Columba, written by Adomnán, describes the saint calming a beast in the River Ness. Whether this has anything to do with the modern legend is debated, and most historians treat it as a story about a saint rather than a record of an animal.
The modern wave
The modern legend began in 1933. A new road was built along the shore of the loch, which opened up views and brought more traffic, and local newspapers began to report sightings. A story in the Inverness Courier spoke of a strange spectacle on the water. National papers picked it up, and the Daily Mail sent a big-game hunter, Marmaduke Wetherell, to investigate.
Wetherell found large footprints on the shore in December 1933. Experts at the Natural History Museum examined casts of the prints and concluded that they had been made with a hippopotamus foot, probably one that had been made into an ashtray or umbrella stand. The incident embarrassed Wetherell, and it would matter later.
The Surgeon's Photograph
On 21 April 1934, the Daily Mail published a photograph that quickly became the best-known image of the monster. It showed a small, dark neck and head rising from the water, with ripples around it. The photo was credited to Colonel Robert Kenneth Wilson, a London gynaecologist, which is why it became known as the Surgeon's Photograph. Wilson said that he had been driving along the loch when he saw something in the water, and had stopped to take pictures. He asked not to be named in the newspaper, so the image became known simply by his profession.
For sixty years, the photo was widely accepted as the best evidence that something lived in Loch Ness.
The exposure
In 1994, the Sunday Telegraph published a story, based on research by investigators including David Martin and Alastair Boyd, that told another version. It said that the photograph was a hoax devised by Marmaduke Wetherell, who wanted revenge on the Daily Mail after the footprint embarrassment. His stepson, Christian Spurling, made a small model sea monster head and neck, and attached it to a toy submarine. The model was photographed in shallow water near the shore, and Wilson, a respected figure, was used as the public source so that the picture would be believed.
Spurling is said to have confessed before his death in 1993, and the account was published the following year. Because the photo was cropped, the small scale of the ripples had been hard to judge. In the uncropped version, the ripples are very small, which matches a toy-sized object.
Later searches
The legend continued without the famous photo. Over the decades there were sonar surveys, underwater photographs and large expeditions. Some produced interesting but ambiguous results. Others, such as the 1970s underwater pictures attributed to Robert Rines, were not accepted by most scientists, who pointed out that the images had been enhanced and were hard to interpret.
In 2018, a team led by Professor Neil Gemmell of the University of Otago collected water samples from around the loch and analysed the environmental DNA, tiny traces left by living things. They catalogued thousands of species and found no evidence of reptile DNA, and no sign of a large animal such as a plesiosaur. They did find a great deal of eel DNA, and Gemmell said the possibility of unusually large eels could not be ruled out, though he considered it unlikely.
Why people keep looking
The monster endures because it is a mystery with no downside. The loch is real and beautiful, and a sighting is a good story. There are plenty of ordinary things to see on a lake: waves, boat wakes, floating logs, swimming birds, and otters. The human brain is also very good at seeing a creature in a shape.
What we can learn
- The best-known evidence for a mystery can be the least reliable.
- A respected witness is not proof; a respectable name was used to give the photo credibility.
- Modern tools, such as DNA sampling, can answer questions that were once impossible to test.
- A mystery can be valuable even when the answer is disappointing.
A fair conclusion
There is no scientific evidence for a large unknown animal in Loch Ness. The legend remains a lasting piece of folklore, and the most famous photograph was a hoax. If you ever visit, bring a camera, and enjoy the scenery; just treat any blurry shape with a healthy degree of scepticism.
