Neal Elgar Miller was an American experimental psychologist. Described as an energetic man with a variety of interests, including physics, biology and writing, Miller entered the field of psychology to pursue these. A Review of General Psychology survey, published in 2002, ranked Miller as the eighth most cited psychologist of the 20th century. Neal E. Miller was born in Milwaukee, Wisconsin on August 3, 1909. He grew up in the Pacific Northwest.  He received a B.S. degree from the University of Washington (1931), an M.S. from Stanford University (1932), and a Ph.D. degree in Psychology from Yale University (1935).

Miller was also one of the founding fathers behind the idea of biofeedback. Today, many of his ideas have been expanded and added to, but Miller has been credited with coming up with most of the basic ideas behind biofeedback. Miller was doing experimentation on conditioning and rats when he discovered biofeedback. Miller was appointed professor of psychology at Yale in 1950, resigning the position in 1966 to accept a professorship at Rockefeller University (1981). In 1985 he became a research affiliate at Yale University. In 1964 he received the National Medal of Science from President Johnson, the first psychologist to receive this honor. Neal Miller died on March 23, 2002, in Hamden, Connecticut.
