John Geissman heads the department of geosciences at the University of Texas at Dallas, responsible for the education of the next generation of geoscientists. He is also a member of the development board of the American Geophysical Union (AGU), a perch from where he works to raise money for the organization. He has included a substantial bequest for the AGU in his will, as well.

And frankly, I really worry about that happening.
