I'm quite sad to hear that Mary has passed.  Like most of you, I got lots of help from her and also learned a lot from her.  First, I was a student helper to Mr. Buffum in the early 1960s, and then later, I arrived at UCLA to supervise the supercomputing consultants and to plan and develop the OAC's shared Visualization Laboratory in the early 1990s and she stepped right up to the plate.

One of the things about that I really appreciated was her ability to see the use of new technology in places that, historically at least, had no apparent use for computing.  Having spent 19 years at the University of Florida working exactly on that issue, I'd found somebody else with some interesting ideas that we discussed and followed up on.  Especially, both of us found  ways to tackle recalcitrant faculty and other researchers.  Some of these we were able to persuade to see the correctness of our views and get some really significant research going.  It wouldn't have been possible without her efforts.
