This is so sad. I met him once when my company was doing some work for Vulcan and I was impressed that his manner was so understated but SHARP, he just "got" things very quickly.

My favorite anecdote from that time period was someone telling me that the first time they met him they were seated next to each other at dinner and he turned and asked "So, what's your favorite shark?"

(I mean I think it was at a dinner for something to do with the ocean/sharks so not totally crazy, but still - charming)

RIP
