Tim Dinsdale

Timothy Kay Dinsdale (27 September 1924 – 14 December 1987) was a British cryptozoologist who attempted to prove the existence of the Loch Ness Monster.

Life Dinsdale was born in Aberystwyth, Wales, The 10-year-old Dinsdale wrote an account of the adventure which received second prize in a competition run by a local newspaper, his first success as a writer.

In 1936 he and his brother returned to Britain to attend King's School, Worcester

JARIC's estimates of the size and speed of the object are now believed to be overestimates due to miscalculations of the angle of the camera and cuts in the film. Analyses overlaying multiple frames seems to show a pale blob towards the rear end of the object, which appears in multiple frames and matches with the position of the helmsman of a boat at the stern by an engine, similar to that of the boat used by Dinsdale for comparison. Although Dinsdale attempted to rule this out by organizing for a small boat to sail a similar route later that morning, this comparison was filmed under different lighting conditions with a white boat unlike the mahogany red colour he had described the object to be. It has also been noted that the object in film does not actually submerge as often perceived but blends into the greyer reflections of the water in the monochromatic film. Although Dinsdale asserted he viewed the object clearly with binoculars, they actually had a wider field of view than his telephoto lens. A computer enhancement of the film done for 1993 Discovery Channel documentary Loch Ness Discovered claimed to shadow or a body of a large animal behind the hump underwater, but such a shadow would not be visible in the conditions and is likely reflections of the shore behind the object.

Although most researchers do not believe Dinsdale to be a hoaxer, his susceptibility to confirmation bias and trusting dubious sources as evidence of the monster's existence has been criticized.

Later search efforts In 1967 he received a grant from Kodak for photographic equipment to help in his search.

He had other sightings including what he described as a head and neck:

Despite as many visits to the Loch as he could afford, he failed to obtain any more film footage.

In July 1987 at a two-day symposium in the Royal Scottish Museum's Natural History Department he was made an Honorary Member of the International Society of Cryptozoology (ISC) for

In April 2020, the binoculars which Dinsdale used during his expedition featured in an episode of the BBC series The Repair Shop.
