[Editor's note: My dad died on May 31, 2020. I'm setting up this blog post as a tribute and a shrine to one of the smartest and humblest people I've ever met. Even most of his co-workers were unaware of his level of accomplishment. This post has nothing at all to do with photography, but read on and get to know a most remarkable person. -GF]
