W. Marshall Leach, Jr., received B.S. and M.S. degrees in electrical engineering from the University of South Carolina, Columbia, in 1962 and 1964, and a Ph.D. degree in electrical engineering from the Georgia Institute of Technology, Atlanta, in 1972. In 1964 he worked at NASA in Hampton, Virginia. From 1965 to 1968 he served as an officer in the U.S. Air Force. Since 1972 he has been a faculty member at the Georgia Institute of Technology where he is presently associate professor of electrical engineering. His interests are applied electromagnetics, audio and electroacoustics. and electronic circuit design. Dr. Leach is a member of the IEEE, the Audio Engineering Society, Sigma Xi, Tau Beta Pi, Eta Kappa No, Omicron Delta Kappa, and Phi Beta Kappa.
