Tim Dinsdale

Born in Aberystwyth, son of Felix and Dorys (Smith) Dinsdale, he attended King's School, Worcester.[1] In 1943, after graduated in De Havilland Aeronautical Technical School, he served in the Royal Air Force and worked as an aeronautical engineer.

Determined to prove the existence of the Loch Ness Monster, Dinsdale travelled to Loch Ness on an expedition. On the fifth day, 23 April 1960, he filmed an object he would claim to be the hump of the monster. The grainy film is still believed by some to be proof of the existence of the monster. The Joint Air Reconnaissance Intelligence Centre analyzed it and believed it was an animate object - later researchers have suggested the footage is of a motorboat but Dinsdale filmed a motorboat for comparison with his original footage and this has confused many (or allowed them to cast doubt on the film even with a knowledge of the history). Dinsdale dedicated his life to obtaining further evidence, taking part in a total of 56 expeditions, many of them solo. Although he claimed to have later seen the monster's head and neck on two occasions, he failed to obtain any more film footage. He also published several books on the subject.

Dinsdale died because of a heart attack in Reading aged 63 in 1987. He was married in 1951 to Wendy Dinsdale and had four children: Simon, Alexandra, Dawn, Angus.

He is commemorated in the Dinsdale Memorial Award.
