James Ross MacDonald

Marrying Margaret Milward Taylor in 1946after leaving the Navy, he returned to MIT, where he worked on Project Whirlwind, an early vacuum-tube, room-size computer.

Upon taking early retirement from Texas Instruments in 1974, he joined the Department of Physics and Astronomy of the University of North Carolina at Chapel Hill as the William R. Kenan Jr.

In 1988, he was awarded the IEEE Edison Gold Medal "for seminal contributions to solid state science and technology, and outstanding leadership as a research director.

Its further development and eventual incorporation as a program in LEVMW has made it an exceptionally valuable and widely applicable data fitting and interpretation model.

During his years at UNC, in addition to his productive teaching and research activities, he and his associates developed LEVM, a ground-breaking computer-oriented immittance- spectroscopy data analysis program which he continued to improve and keep up to date after his retirement.

[1] His published work, as well as a pioneering 1987 book on Impedance Spectroscopy (currently in its third edition) that he edited and to which he was a major contributor, and his continuing help to students and colleagues around the world in using LEVM/LEVMW for impedance spectroscopy data analysis, resulted in international recognition for his experimental and theoretical contributions to condensed matter physics, electrochemistry, and data analysis.
