8739 Morihisa           Discovered 1997 Jan. 30 by T. Kobayashi at Oizumi.
In addition to his own petrological research, Morihisa Suzuki (b. 1944), a professor at Hiroshima University, has taught earth science, using rocks and meteorites he himself collected in Antarctica. This effective way of using the relationship between space and the earth resulted in the education of many excellent science teachers.
