Oral History Center, The Bancroft Library, University of California Berkeley Oral History Center University of California The Bancroft Library Berkeley, California Paul Gray: A Career in Electrical Engineering, UC Berkeley Administration, and Private Sector Leadership Interviews conducted by Paul Burnett in 2017 and 2018 Copyright © 2018 by The Regents of the University of California Oral History Center, The Bancroft Library, University of California Berkeley ii Since 1954 the Oral History Center of the Bancroft Library, formerly the Regional Oral History Office, has been interviewing leading participants in or well-placed witnesses to major events in the development of Northern California, the West, and the nation. Oral History is a method of collecting historical information through tape-recorded interviews between a narrator with firsthand knowledge of historically significant events and a well-informed interviewer, with the goal of preserving substantive additions to the historical record. The tape recording is transcribed, lightly edited for continuity and clarity, and reviewed by the interviewee. The corrected manuscript is bound with photographs and illustrative materials and placed in The Bancroft Library at the University of California, Berkeley, and in other research collections for scholarly use. Because it is primary material, oral history is not intended to present the final, verified, or complete narrative of events. It is a spoken account, offered by the interviewee in response to questioning, and as such it is reflective, partisan, deeply involved, and irreplaceable. ********************************* All uses of this manuscript are covered by a legal agreement between The Regents of the University of California and Paul Gray dated August 22, 2018.

Oral History Center, The Bancroft Library, University of California Berkeley iii Paul R. Gray, 2005 Oral History Center, The Bancroft Library, University of California Berkeley iv Paul Gray is Professor Emeritus of Engineering in the Department of Electrical Engineering and Computer Science at UC Berkeley. A graduate of the University of Arizona, Dr. Gray worked at Fairchild Semiconductor before joining UC Berkeley EECS in 1971. There he developed a multi-decade research project on digital-analog conversion and the thermal properties of integrated circuits, which laid the foundation for digital telecommunications, scientific instrumentation, and digital representations of the analog world. He served as Chair of EECS (1990-93), Dean of the College of Engineering (1996-2000), Executive Vice Chancellor and Provost of UC Berkeley (2000-06). He has served on the boards of several corporations, in addition to the board of the Gordon and Betty Moore Foundation.
