EECS Prof. Emeritus and alumnus Arthur Gill (Ph.D. ’59, advisor: Aram Thomasian) died on March 21, 2020, at the age of 90. Gill joined the EECS faculty in 1960, just after earning his doctorate, and was one of the first professors at Berkeley to hold positions in both EE and CS before the formation of the EECS department in 1968. His research focused on network analysis and synthesis, communication theory, system theory, and computer science. He was an active member of the Electronics Research Laboratory for the duration of his 30 year career, and Assistant Dean for Undergraduate Affairs in the College of Engineering from 1981 to 1991. He was the first faculty ‘supervisor’ of the Computer Science Reentry Program, an early, innovative, and successful effort to increase the number of women and minority students studying CS at Berkeley. Gill is survived by his children, Jonathan and Leori Gill, their children and grandchildren, and his long-time partner in life and travel, Marijke Van Doorn (widow of EECS Prof. Eugene Lawler).
