content: Albert Melvin Grass (1910-1992), an electrical engineer recently graduated from M.I.T., joined the Department of Physiology at the Harvard Medical School in 1935 and was tasked with building an early E.E.G. machine. Ellen H. Robinson (1914-2001), a biologist from Radcliffe College, was a graduate student in the Department. The two married soon thereafter and embarked on careers of designing and building E.E.G. machines and promoting their use for medical and scientific purposes. The Grass Instrument Co., in Quincy, Ma., produced the equipment. The Grass Foundation supported young scientists. This Polygraph Recorder, Model 7D, made by the Grass Instrument Co., is a dummy instrument made for exhibit purposes.
