Reports of a monster inhabiting Loch Ness date back to ancient times. Notably, local stone carvings by the Pict depict a mysterious beast with flippers. The first written account appears in a biography of St. Columba from 565 AD. According to that work, the monster bit a swimmer and was prepared to attack another man when Columba intervened, ordering the beast to "go back." It obeyed, and over the centuries only occasional sightings were reported. Many of these alleged encounters seemed inspired by Scottish folklore, which abounds with mythical water creatures.?

In 1933 the Loch Ness monster’s legend began to grow. At the time, a road adjacent to Loch Ness was finished, offering an unobstructed view of the lake. In April a couple saw an enormous animal—which they compared to a “dragon or prehistoric monster”—and after it crossed their car’s path, it disappeared into the water. The incident was reported in a Scottish newspaper, and numerous sightings followed.

The news only seemed to spur efforts to prove the monster’s existence. In 1934 English physician Robert Kenneth Wilson photographed the alleged creature. The iconic image—known as the “surgeon’s photograph”—appeared to show the monster’s small head and neck. The Daily Mail printed the photograph, sparking an international sensation. Many speculated that the creature was a plesiosaur, a marine reptile that went extinct some 65.5 million years ago. The Loch Ness area attracted numerous monster hunters. Over the years, several sonar explorations (notably in 1987 and 2003) were undertaken to locate the creature, but none were successful. In addition, numerous photographs allegedly showed the beast, but most were discredited as fakes or as depicting other animals or objects. Notably, in 1994 it was revealed that Wilson’s photograph was a hoax spearheaded by a revenge-seeking Wetherell; the “monster” was actually a plastic-and-wooden head attached to a toy submarine. Despite the lack of conclusive evidence, the Loch Ness monster remained popular
