Establishment of American Board of Psychiatry and Neurology, with separate examinations and certifications for each specialty (Stevens, 222-225; Gavrus, 71). Hallowell David at Harvard approaches Albert Grass (’34 MIT grad) to build first EEG machine: “As epilepsy centers proliferated through the country, the Grass Company flourished and became the leading commercial enterprise in manufacturing EEG machines” (Rowland, 30). After Hallowell recorded his own normal EEG, Fred and Erna Gibbs were first to record a petit mal seizure, and they induced Albert Grass to build a practical EEG machine in 1936 (34).
