Professor PK Thomas, a past President of the Association of British Neurologists, has made outstanding contributions to neurology, as investigator, clinician, author, educator, and editor. "PK", as he is universally and affectionately known, trained with JZ Young in the Anatomy Department at University College. After working at the Middlesex, the National, and Montreal General hospitals, he was appointed consultant at the Royal Free Hospital in 1962, and soon afterwards at the National and Royal National Orthopaedic Hospitals. In 1974 he became Professor of Neurology at the Royal Free Hospital School of Medicine and the Institute of Neurology. His research output has continued unchecked following the conferment of his emeritus title in 1991. His formidable publication record includes, so far, 211 original articles, 61 review articles, 100 book chapters and 13 books. He pioneered the study of cutaneous nerve biopsy and illuminated many aspects of peripheral nerve structure and function. His research has improved our understanding and management of nerve injury and inherited, metabolic and inflammatory neuropathies. His publications are models of scholarship, written with the meticulous care which he generously shares with authors who submit articles to the books and journals which he edits. PK has already earned the respect of the international neurological community and been honoured by his country as Commander of the British Empire. Last year the Association of British Neurologists took solace from awarding one of its first medals to PK's greatly loved wife, Anita Harding. This year the Association is proud to award its Medal to PK himself, in admiration of his science, his scholarship, his unflagging energy and his unfailing fortitude.
