Lyman Chapin

Lyman Chapin is Chief Scientist at BBN Technologies, a division of Verizon. He graduated from Cornell
University in 1973 with a B.A. in Mathematics and spent the next two years writing time-sharing
applications in COBOL for Systems & Programs Ltd. in New Zealand. In 1977 he joined the newly-formed
Networking Group at Data General Corporation, where he was responsible for distributed resource and
database management, local and wide area network architecture, and OSI-based transport, internetwork,
and routing functions for DG’s open-system hardware and software products. He joined BBN (then Bolt,
Beranek & Newman) in 1990 as Chief Network Architect in the Communications Division. His current
professional interests include mobile networking, information security and personal privacy, electronic
commerce, and electronic payment systems.

Mr. Chapin is a Fellow of the IEEE, and has been an active contributor to the Internet and global
networking for more than 25 years, with a particular emphasis on network architecture, internetwork
protocols, and naming and addressing. He has served as chairman of the Internet Architecture Board (IAB),
the ACM Special Interest Group on Data Communication (SIGCOMM), and the ANSI and ISO standards
groups responsible for Network and Transport protocols, and was a founding trustee of the Internet Society.
In 1997 he co-founded the Wiley Networking Council publishing series at John Wiley & Sons. He is the
co-author of Open Systems Networking —TCP/IP and OSI, which was published in 1993 by Addison-Wesley.

Mr. Chapin currently serves as the USA (ACM) representative to the International Federation for
Information Processing (IFIP) Technical Committee on Communication Systems (TC6), and as the USA
representative to the NATO Science Committee’s networking panel. He lives with his wife and two
daughters in Hopkinton, MA.
