10601 Hiwatashi           Discovered 1996 Oct. 16 by A. Nakamura at Kuma Kogen.
Named in honor of Kenji Hiwatashi (b. 1922), electrical engineer at NHK (Japan Broadcasting Corporation) from 1947 to 1979, on the occasion of his Kiju celebration (77th birthday). A pioneer in the field of human visual information processing research, Hiwatashi authored nine books and co-authored another 20, some of which have been the fundamental textbooks used by researchers in this field. More recently, he served as a professor at the Institute of Information Sciences and Electronics, University of Tsukuba (1979-1986), and as professor of electronics at Meisei University (1986-1996).
