William Garner Sutherland as a child was encouraged to ‘dig on’ in the family potato patch. He found that the more he dug, the more rewarding the digging became. He carried that philosophy throughout his whole life. Dr Sutherland observed a disarticulated skull in osteopathic school and was struck with the idea that the adjacent surfaces were designed for motion. He could fi nd no substantiation for that, so with a great deal of bravery he experimented with his own head, dug on and proved his ‘skull motion’. He initially dealt only with adults, but with his great success was subsequently asked to treat infants and children. He provided many clinical cases by volunteering to work at an institute for handicapped children, and again met with great success. Dr Sutherland minimized his contribution by saying he had ‘only pulled aside a curtain.’ But what a tremendous vista that curtain has revealed! Cranio-sacral osteopathy has made a tremendous contribution to health care and has probably had a greater impact in helping infants and children realize their full potential, than in correcting the many adult problems which occur. This is not to minimize its benefi t in that area.
