Hiroshi Wada was a pioneer in Japanese semiconductor and computer technologies in post-World War II Japan. His influence is widely felt in diverse technical fields, including semiconductor manufacturing, computer technology, information processing, and character code standardization. He also played an instrumental role in shaping the high-technology policy during the postwar reconstruction of Japan.

1. Wada's doctoral thesis was entitled "Research on Electrode-type Electric Boiler."
2. For an overview of Wada's career, see Y. Nakagawa, Nihon no handōtai kaihatsu [The Development of Semiconductors in Japan], Daiyamondo-sha, 1980, p. 40; and S. Takahashi, "Japanese Computer Pioneers: Wada Hiroshi, 1914–2007"; see http://www.ipsj.or.jp/katsudou/museum/pioneer h-wada_e.html; S.

3. Wada quoted in Nakagawa, p. 40.
4. The only record of Wada in the von Hippel papers at MIT is in the "List of Former Lab Members," n.d., box 3, folder 11, Archives Collection #321, MIT Archives, Cambridge, Mass. Wada quoted in Nakagawa, p. 41.

16. S. Takahashi, "A Brief History of the Japanese Computer Industry Before 1985," IEEE Annals of the History of Computing, vol. 18, no. 1, 1996, pp. 76-79, During this period, Japanese researchers at the Electrical Communications Laboratory had been working on a digital computer based on an indigenous electronic logic element called "parametron," invented in 1954 by Ei'ichi Goto, a graduate student at the University of Tokyo. The two-pronged strategy for technical development was typical in Japanese research management since the Meiji era. See M. Fransman, The Market and Beyond: Cooperation and Competition in Information Technology Development in the Japanese System, Cambridge Univ. Press, 1990, pp. 13-23.
