David B. Rutledge (born 1952) is the Kiyo and Eiko Tomiyasu Professor (em.) of Engineering and former chair of the Division of Engineering and Applied Science at the California Institute of Technology (Caltech), United States. His earlier work on microwave circuits has been important for various advances in wireless communications and has been useful for applications such as radar, remote sensing, and satellite broadcasting. He also covers research in estimating fossil-fuel supplies, and the implications for alternative energy sources and climate change.
Education
Rutledge earned his bachelor's degree at Williams College, his Master of Arts degree from the University of Cambridge, and his doctorate from University of California, Berkeley.
Career
He joined the Caltech faculty as an assistant professor in 1980, and rose through the faculty ranks to become the holder of the Tomiyasu chair in 2001. He served as executive officer for electrical engineering from 1999 to 2002 and chair of the Division of Engineering and Applied Science from 2005 to 2008. Rutledge was editor-in-chief of the journal IEEE Transactions on Microwave Theory and Techniques. He was also a member of Caltech's Lee Center for Advanced Networking, which aimed to create a global communication system that is as reliable and robust as a basic utility. Since 2018 he is a professor emeritus.
Published works
Rutledge is the author of Energy: Supply and Demand, a book published by Cambridge University Press, December 2019.
Begin with the source’s own compact description: “David Rutledge (engineer)” is american engineer. The dossier treats that line as a proposition to test through David, Rutledge and engineer, not as a finished interpretation.
Why this record matters
The phrase “american engineer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q5239323. VIAF identifies the subject as 17480663. The Library of Congress control number is n98070001. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1952, 1980, 2001 and 1999.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
