Cottam C, MacGillivray Smith E, The Roots of Cranial Manipulation Nephi Cottam and "Craniopathy" Chiropractic History 1981; 1(1): 31-5.

Cranial manipulation is a procedure recognized for limited Medicare payment, and while always controversial the origins of the technique itself have been the subject of dispute. Advocates and practitioners of Nephi Cottam, an American chiropractor, and William G. Sutherland, a Canadian osteopath, have both claimed priority. This paper advances a case for establishing "craniopathy" as formulated by Cottam as the first school of instruction and practice in this specialty.
