"Motor homunculus" from Penfield and Rasmussen
The Cerebral Cortex of Man (1950)

McGill and Chicago
     For the next two years he was Assistant Neurosurgeon and Lecturer in Neurology and Neurosurgery at McGill, during which time he worked on the detailed analyses of cortical localization of sensory, motor and speech function in four hundred patients on whom brain mapping had been carried out as part of the surgical treatment of epilepsy. The resulting monograph by Penfield and Rasmussen, The Cerebral Cortex of Man, published in 1950, became one of the classical references in this field. It included extensive maps of the sensory and motor cortex and, derived from those, new versions of the familiar homunculus.
In 1947 Dr Rasmussen was appointed Professor of Neurological Surgery at the University of Chicago. Here he initiated a project using radioactive yttrium to deliver beta-radiation to ablate the pituitary gland to treat patients with metastatic cancer. He and his father also notably reported on the histology of the pituitary gland of "Bushman", a 500-lb gorilla from the Lincoln Park Zoo who had succumbed to a strange peripheral neuropathy.

      In 1954 Dr Rasmussen became Professor and Chairman of Neurology and Neurosurgery at McGill and when Wilder Penfield retired in 1960, Rasmussen succeeded him as Director of the Montreal Neurological Institute. He also served as Neurologist and Neurosurgeon-in-Chief of the Royal Victoria Hospital. In 1963, in response to provincial legislation, the Montreal Neurological Hospital was constituted, legally separating the hospital from the teaching and research institute; Rasmussen thus took on the title of the first Director-General. He efficiently administered the Institute, Hospital and Department from 1954 to 1972 in a well-ordered and evenhanded manner; during that same time he continued in active surgical practice.

     I first came to know Ted Rasmussen in June of 1942, when I came from Dalhousie Medical School for two weeks at the Neuro to learn techniques for examining peripheral nerves. Dr Penfield assigned Dr Rasmussen as my mentor. He was the Fellow in neuropathology and gave me a "Madrid cubicle" in the lab. I quickly went through the techniques of Bielschowsky, Bodian and Weigert under his watchful eye. He was kindness itself. It was a warm June and the opened windows of the lab were our only air conditioning. A bagpiper appeared for several nights in Molson Stadium practicing vigorously. By the third night, Ted could stand it no longer and said, "Let's go to a movie". On the way down University Street he recited the records to the minute and second of the main track and field champions at that time. We became good friends for the next sixty years.
