Named in memory of Hugh Odishaw (1916–1984), an organizer in international geophysical research during a time of revolution in Earth and space sciences. He served as executive director of the U.S. committee for the International Geophysical Year, director of the IGY World Data Center, executive director of the Space Science Board, executive secretary of the U.S. National Academy of Sciences’ division of physical sciences and dean of the University of Arizona’s college of Earth and space sciences. His excitement and enthusiasm about the recent flood of discoveries in geophysics led to a television film series, Planet Earth, premiered not long after his death. (M 12968) _ _.
