John Dylan Morgan (3 May 1946 – 5 March 2011) was a mathematician, physicist, hypnotherapist, and author. He developed a theoretical approach to hypnotherapy which he published in his book Principles of Hypnotherapy. He also made contributions in theoretical and applied physics.
Early life and education
He had a scholarship to study at Jesus College Oxford and graduated with a first class honours degree in Mathematics. He then obtained a doctorate in Elementary Particle Theory from the University of Oxford.
Dylan Morgan joined the Mathematics Department of Dundee University in 1970 as a researcher. He worked on noise generated by high speed jet engines, as well as the noise generated by high speed helicopter rotors.
He also served as a Senior Scientific Officer at the Royal Aircraft Establishment.
Motivated by a desire to help people in 1983 Dr Morgan decided on a change of career and decided to become a hypnotherapist. He was self-taught and this allowed him to work out his own original theory for guiding his practice. This theory is presented in his book The Principles of Hypnotherapy which aims to provide a complete theory of hypnosis and hypnotherapy.
For a few years he also helped at the Leeds University Psychology Department to run courses on hypnosis for qualified doctors, dentists etc.
He was the editor of the Journal of the National Council of Psychotherapists and Hypnotherapy Register from 1983 to 1987.
Dylan Morgan married Trudi Yates, a fellow student at Oxford, in 1969. They had a daughter in 1981.
Since his school days he had a keen interest in chess and later on he noted playing chess and making chess boards as his hobbies. He also maintained a number of web sites for chess clubs in the Leeds area.
