In 1990, I included the Hilbert Curve in my senior thesis for my BS in Math, which I presented to all the professors in our math department. Years later, one of those professors became a family friend. He was an incredibly supportive mentor to multiple people in our family. After he passed away last year, I learned that his great-great grandfather was David Hilbert, creator of this curve. It must have been fun to see some of his family's work displayed in one of his student's theses.
Silly me, I thought mathematicians reproduced by budding. I assumed that's what they did while reclusing in their mountain shacks between public appearances.
