On November 25, 1884, at the Hospital for Epilepsy and Paralysis and other Diseases of the Nervous System (now Maida Vale Hospital) in London, surgeon Rickman Godlee, led by neurologists A.H. Bennet and David Ferrier, who traced in the skull the major convolutions of the Brain and the exact point where he was to trepanarse, operated from a brain tumor to the young Henderson, native of the county of Dumfries.
One hundred and twenty-five years later this seems to us of no importance and for many it will be a surprise that it wants to give the transcendence of being the birth of a new specialty: Neurosurgery.
The story is not that of an operation more to the brain, which as we know they were done from many centuries before. The transcendence is that it was the first operation of a brain tumor located only by clinical methods.
