I'm very sad to report that Rob Wilson passed away last August. I wanted to at least take notice of his passing here, where he once posted and was moderator. I didn't learn of this until this week.
Though I never met him personally, I was helped and encouraged greatly by him, both here on the forum, and privately via occasional emails. I was in awe of his abilities, skill, and knowledge ... a superb craftsman -- he was an artist, really.
It's sad that we can no longer see his amazing work in photos on this, or other fora, but a return to anonymity was his wish in the last few years, and one I respect, though I wish it was otherwise. It was good to have known him and to have been able to appreciate his work and enthusiasm for engineering when it was seen.
My deepest sympathies go out to his family and friends. He is missed by many more than may be realized. I miss him, for sure.
