William Beecher Scoville wrote an extensive letter to the officers of the neurosurgical societies in Europe and America and to outstanding leaders in neurosurgery, explaining the actual situation. As a great majority of the answers to his letter were positive, William Scoville arranged for a meeting of senior European neurosurgeons and representatives of 17 national neurosurgical societies, which was held in Brussels on September 4 and 5, 1955.
After ample discussions and deliberations, it was decided to institute “an international organization composed of and controlled by the component neurosurgical societies”. Thus the birth of the World Federation of Neurosurgical Societies had taken place although the baby had not yet received its official name.
It was officially baptized somewhat later when the Constitution had been drafted and ratified at the executive session during the International Congress of Neurological Sciences in Brussels on the historical date of Saturday, July 20, 1957.
