(((((hugs for the Katz family)))))
This is incredibly tragic. Especially because he had so much going for him-he was clearly a very unique individual with inspiration beyond that of the average person. It's so sad to hear of a loss of someone who did so much for so many others (hearing of any loss is sad, of course, but this is particularly difficult).
The Katz family is in my thoughts. Tamar, if you're reading-condolences for you and your family and I wish you nothing but the best.
