RIP Gregory Greenman aka Morbius. Underneath the occasional curmudgeon-like exterior, Morbius was a gentleman and a scholar and a PF friend. I was wondering why we had not heard from him for a few years so I began looking and, alas, sadly, I came across this January 2015 obituary for him: https://www.llnl.gov/community/retiree-and-employee-resources/in-memoriam/greg-greenman.
