James Hill (30 October 1703 – 18 October 1776) was a Scottish surgeon working in Dumfries who advocated curative excision for cancer rather than the palliative approach adopted by many leading surgeons of the day. By follow-up of his patients over years he demonstrated that his radical approach resulted in better outcomes than those published by contemporaries. His experience in diagnosing and treating intracranial bleeding after head injury by directed trephine resulted in the best results published in the 18th century and represent an important landmark in the management of post-traumatic intracranial haemorrhage.
