Let me spend a few minutes admiring and appreciating the work of Professor Akihiko Yamada. He is elderly and I want to speak of him while I believe he is still with us.
Yamada has been this department’s most dependable contributor within the last couple of decades. A less than thorough search shows 28 Events and Sightings pieces by him since 2006 — an impressive aid about history-of-computing activities in Japan. In addition to his writings for the Annals, Professor Yamada served at various times on the Computer Society History Committee, was a member of the Society’s Board of Governors, and lent significant support to opening the IEEE Computer Society's Tokyo office — IEEE's first office in the Asia-Pacific region). He also published on computing history in Japan.
As an expression of Yamada’s support of other researchers, in 2015 Radomir Stankovic collected and prepared a small book of Yamada’s comments about computing history in Japan: Comments by Akihiko Yamada — History of Computing in Japan (annals-extras.org/pubs/es-2015-yamada-comments.pdf). This booklet is one of several history publications with which Stankovic has been involved in a belief that it is important that technologists be aware of the history of their technology.
My understanding is that Yamada had an impressive technical career at NEC. He has an undergraduate degree and a doctoral degree from Osaka University. After retirement from NEC, he taught at Tokyo Metropolitan University, Tokyo Denki University and Cyber University. He became a Fellow of the Information Processing Society of Japan (IPSJ) in 2002, given IPSJ Contribution Award in 2008, and declared IPSJ Honorary Member in 2018. Tsutomu Sasao has pointed me to Professor Yamada’s involvement in a very recent publication on computing in Japan: Remarks on the Design of First Digital Computers in Japan — Contributions of Yasuo Komamiya, lsi-cad.com/sasao/Papers/files/EUROCAST2019_stanko.pdf
