A giant in stroke prevention: first to show that Aspirin reduced the risk of stroke; led the study that showed that carotid endarterectomy reduced the risk of stroke in patients with symptomatic carotid stenosis, and the study that showed that extra-cranial to intracranial bypass was not effective. Founding chair of the department of Clinical Neurological Sciences at the University of Western Ontario, in which Neurology and Neurosurgery joined to form a department separate from Medicine and Surgery. This model, which he pioneered with his neurosurgical colleague Charlie Drake, has been copied successfully the world over.
