The American public felt the impact of neurological disease when United States President Franklin D. Roosevelt died suddenly on April 13, 1945, from cerebral hemorrhage. He had suffered from uncontrolled hypertension and had been paraplegic from 1921 due to paralytic poliomyelitis.

         During 1945, the majority of neurological publications in Allied Countries related to war injuries, exposure to heat and cold, aviation medicine and clinical neurophysiology. Derek Denny-Brown (1901-1981) immigrated to United States from England to become Physician-in-Chief of the Harvard Neurology Service at Boston City Hospital in 1941. He and Doherty stretched peroneal nerves of anesthetized cats and produced epineural hemorrhages, swollen axis cylinders and beading of the myelin. Their observations accounted for the peripheral nerve dysfunction from high velocity gunshot wounds that passed through adjacent tissue.
         Victims of the Nazi killing machine did not die entirely in vain; from Leo Alexander's testimony in 1946, responsible scientists devised the Declaration of Helsinki recommendations to prevent harmful experimentation without informed consent.
         A.B. Baker began his campaign for an inclusive neurological academy that would serve members from the beginning of residency through emeritus status and provide educational opportunities to level the playing field by providing courses to overcome weakness in training programs. He recruited other young neurologists including: Russell DeJong of University of Michigan, Francis Forster then of Thomas Jefferson University (Philadelphia), and Adolph Sahs of University of Iowa. Baker and these three colleagues became known as the Four Horsemen of the American Academy of Neurology. The first scientific meeting of the AAN was held at in 1948.
