Biographical / Historical

Albert M. Grass (1910-1992), B.S., 1934, Massachusetts Institute of Technology, Cambridge, Massachusetts, was a neurophysiological instrument engineer and co-founder of the Grass Instrument Company. In 1935, Grass and his brother Everett built a 3-channel electroencephalograph (EEG) commissioned by Frederic A. Gibbs to measure alterations in brain wave activity associated with epileptic seizures. Grass joined Gibbs at the Department of Physiology at Harvard Medical School (HMS) as Instrument Engineer later that year. He left HMS in 1943 and founded the Grass Instrument Company with his wife and professional partner Ellen R. Grass in 1945. The Grass Instrument Company was a leading supplier of EEG equipment for clinical and research use. Albert and Ellen Grass also co-founded the Grass Foundation in 1955, which supports neurophysiology research and innovation.
