I had the great fortune to meet him in 2011. As it says in his obit, he was very active in his community - which is where I live. I remember back in high school reading Gateway and loving it. When I got to the end, and read the about the author section (yes, someone reads those), I found out he lived in my own town! He was even in the phone book! However, I was terrified of being some sort of stalker, so I never acted upon it.
Fast forward 21 years later, I met him at our local library. I told him this story and he told me I should have stopped by. He said he loved when people talked to him about his writing, and that was why he was listed in the directory! Despite being fairly ill at the time, and having recently had a nasty fall that left him with a large cut on his balding head, he was spry and quick witted. I sheepishly got his autograph and a picture to remember the moment. I was even showing the picture to my kids a few months ago, sharing with them my enjoyment at meeting such a distinguished writer.
