Not quite, unfortunately! I almost had the opportunity, briefly, in 2019 when I was contributing some patterns to a short film that Will Cavendish was working on with Conway, called "Thoughts on Life":

But there was never really a good excuse to arrange a meeting, given Conway's very fragile health at that point -- and then COVID came along.
Conway regularly attended the bi-annual Gatherings for Gardner in Atlanta for quite a while, but by the time I started attending he could no longer travel that far.
Not the author but I'd often seen him at the local coffee shop in Princeton reading or working. He was incredibly kind and generous with his time (I also made sure to not ask about GoL because I'd read about his feelings regarding it). He even showed my 6 year old a few puzzles. Even though we'd see him all the time, each time was like seeing a celebrity for me.
