8735 Yoshiosakai           Discovered 1997 Jan. 2 by T. Kobayashi at Oizumi.
Sakai Yoshio (1923-2002) is a pioneer in building astronomical observatories for the general public. He established the Hidahiko Tenmondai at his own expense. He also toiled as director of Ogawa Astronomical Observatory (founded in 1991), contributing much to education in astronomy.
