476 | NOTES ON THE CONTRIBUTORS
Brian E. Carpenter is an Honorary Professor of Computer Science at the University of Auckland. His
research interests are in Internet protocols, especially the networking and routing layers, as well as
computing history. He was an IBM Distinguished Engineer working on Internet standards and tech-
nology from 1997 to 2007. Earlier he led the networking group at CERN, the European Laboratory for
Particle Physics from 1985 to 1996. He chaired the Internet Engineering Task Force from 2005 to 2007,
the Board of the Internet Society from 2000 to 2002, and the Internet Architecture Board from 1995 to
- He holds a first degree in physics and a PhD degree in computer science.
Catherine Caughey (1923–2008) was called up for war service in 1943. After a rigorous interview and test-
ing process she was assigned to work at Bletchley Park, where she used the Colossus computers for deci-
phering German High Command messages. After the war she attended Dorset House in Oxford where
she trained as an occupational therapist; after qualifying, she worked in an Oxford psychiatric hospital.
B. Jack Copeland, FRS NZ, is Distinguished Professor in Arts at the University of Canterbury, New
Zealand, where he is Director of the Turing Archive for the History of Computing. He has been
script advisor and scientific consultant for a number of recent documentaries about Turing. Jack is
co-director of the Turing Centre at the Swiss Federal Institute of Technology (ETH), Zurich, and also
Honorary Research Professor in the School of Historical and Philosophical Inquiry at the University
of Queensland, Australia. In 2012 he was Royden B. Davis Visiting Chair of Interdisciplinary Studies
in the Department of Psychology at Georgetown University, Washington, DC, and in 2015–16 was
a Fellow at the Institute for Advanced Studies in Israel. A Londoner by birth, he earned a DPhil in
mathematical logic from the University of Oxford, where he was taught by Turing’s great friend Robin
Gandy. His books include a highly accessible biography Turing, Pioneer of the Information Age as well
as Colossus: The Secrets of Bletchley Park’s Codebreaking Computers; The Essential Turing; Alan Turing’s
Electronic Brain; Computability: Turing, Gödel, Church, and Beyond (with Oron Shagrir and Carl Posy);
Logic and Reality; and Artificial Intelligence. He has published more than one hundred articles on the
philosophy, history, and foundations of computing, and on mathematical and philosophical logic. He
was the recipient of the 2016 Covey Award, recognizing a substantial record of innovative research in
the field of computing and philosophy.
Robert W. Doran is Professor Emeritus of Computer Science at the University of Auckland, where he
was head of department for many years. He has had a lifelong interest in the history of computing,
currently maintaining displays and a website on the subject for the Computer Science Department. His
additional interests include parallel algorithms, programming, and computer architecture, and he was
a Principal Computer Architect at Amdahl Corporation in the late 1970s. A graduate of the University
of Canterbury and Stanford University, he has also had appointments at The City University of London
and Massey University.
Rod Downey is Professor of Mathematics at Victoria University of Wellington, New Zealand. His interests
evolve around the theory of computation and computational complexity. He is author of three books,
Fundamentals of Parameterized Complexity; Parameterized Complexity; and Algorithmic Randomness
and Complexity, and is the editor of many volumes, including Turing’s Legacy.
Ivor Grattan-Guinness (1941–2014) was Emeritus Professor of the History of Mathematics and Logic at
Middlesex University, England, and also a Visiting Research Associate in the Centre for Philosophy of
Natural and Social Science at the London School of Economics. He was editor of the history of science
journal Annals of Science from 1974 to 1981. In 1979, he founded the journal History and Philosophy of
Logic, which he edited until 1992. His books include The Search for Mathematical Roots, 1870–1940. He
was the associate editor for mathematician, statistician, and computer scientist entries in the Oxford
Dictionary of National Biography. In 2009, he was awarded the Kenneth O. May Medal and Prize in the
History of Mathematics.
