Named in honor of Tadao Takenouchi (1922– ), who worked variously in the Department of Astronomy of Tokyo University, the Tokyo Astronomical Observatory, the space agency NASDA and the Institute of Space and Astronautical Sciences. During the 1950s he worked with H. Hirose {see planet  (1612)} computing ephemerides of minor planets by hand for the Minor Planet Center. Also by hand, he made a numerical study of the orbit of (279) Thule and examined the behavior of its 4:3 libration with Jupiter over a complete cycle. (M 27329) _ _.
