John McNaughton Epley (1930 – 2019) was an American otolaryngologist.
Epley developed the ‘canalith theory’ of vestibular disease. He published ‘New dimensions of benign paroxysmal positional vertigo‘ in 1980 detailing his eponymous maneuver to treat the condition without the need for medication or surgery.
Over the following 20 years he published a number of papers outlining the canalith repositioning procedure, now recognised as the Epley maneuver.

Epley maneuver (1980)
Key Medical Contributions
Epley published his original Particle Theory for Benign Paroxysmal Positional Vertigo in 1979 outlining the theory of cupulolithiasis in the posterior semicircular canal as the pathophysiological mechanism of the condition. A theory that has since been further demonstrated and widely accepted.
Hypotympanotomy retractor (1979). A retractor designed to allow an inferior oriented approach to the middle ear such as in posterior ampullary nerve transection, the trans-cochlear approach to the internal auditory meatus or glomus tympanicum resection.

Epley faced over a decade of scepticism and ridicule from peers in his field who did not believe in his repositioning manoeuvre. This led to colleagues questioning his medical skills in general and in 1996 The Oregon Board of Medical Examiners notified Epley that he was under investigation for alleged unprofessional conduct. It was not until 2001 that these claims were finally dismissed.
Physicians learn to just do the routine, to do the accepted things — don’t go too far out. They’ve got so much to lose if they stick their neck outEpley
