SPIEGEL, Ernest Adolf
"The first successful cranial application of stereotactic surgery in humans is credited to the team of Ernest Spiegel and Henry Wycis in the Department of Experimental Neurology at Temple University in Philadelphia (Spiegel et al. 1947). Their original frame, using a Cartesian coordinate systems and similar in design and operation to the Clarke-Horsley device, was fixed to a patient’s head by means of a plaster cast. The frame and cast were removable, allowing separate imaging and surgery sessions. Contrast radiography, ventriculography and later pneumoencephalography permitted the visualization of intracranial reference points from which the location of target structures of interest could be determined. Initial applications were for psychosurgery.(Wikipedia article on Ernst Adolf Spiegel, accessed 3-2020)
