Both of these extraordi- nary individuals changed our professional lives and made a significant impact on the fields of intraoperative neurophysiology and neurosurgery. Vahe was French-born neurophysiologist, from Armenian parents, educated in the United Kingdom, where he made part of his professional carrier as a neurophysiologist, and later on moved to the United States where he continued to work with great success and achievement. Vahe’s work on the physiology of the nervous system describing D and I waves of corticospinal neurons [1] was the basis for the development of present methodolo- gies for intraoperative monitoring of motor-evoked potentials. Vahe was actively involved throughout the devel- opment of this methodology. Vahe generously shared his enormous intellectual talent and his vast knowledge. Vahe was always an inspiration for us and our colleagues. Vahe was the quintessential great teacher and mentor youremember for life. Fred was larger than life. Growing up he battled with circumstances that made every academic achievement a hard-earned victory. He beat that, and went on to reach further. Having become an accomplished and leading pediatric neurosurgeon, he developed pioneering surgeries in the brainstem and spinal cord. In doing this he realized the potential of intraoperative neurophysiology. Thus he was a very early advocate of the utilization of intraoperative neurophysiologic techniques to make complex operations in critical areas safer, better, and possi- bleat all. Asa world-renowned neurosurgeon he said, “Monitoring is themostinteresting thing we do here!” Fred had an amazing ability to see forest, when most of us only saw trees. And that applied to his vision of intraoperative neurophysiology. Following this vision he was instrumental in many of intraoperative neurophy- siology’sdevelopments and this bookis testament to thefact that he was right.
