Dr. Harris joined the university’s Department of Physics in 1957 after serving as a physicist at the Naval Research Laboratory. He remained in the Physics Department until his retirement in 1994. In 1975 he was named the Benwood Foundation Distinguished Professor of Physics. He specialized in quantum field theory, statistical physics, plasma, relativity, and cosmology, and he authored two books and over 35 articles in these fields. The books have been called models of clarity, and both were translated into other languages. A paper on plasma oscillations established him as one of the leading plasma physicists in the world. His research has been hailed by colleagues for its sophistication, incisiveness, and originality. He was elected a Fellow of the American Physical Society, and in 1964 served as vice chairman of its Plasma Physics Division. His intellectual contributions to the life of the university have been recognized by placement of a plaque in his honor on a faculty study.
