Randall Munroe's previous incarnation/vampire-fake-name!

Also, it's fun to me when I see a name I know on one of these, Mersenne in this case, and realize that I don't really know why they're famous. Mersenne is near to Heat and Sound on the map, but I know him for his...🤭 Twister, a beautiful dance move that generates high quality pseudo-random numbers. Might not even be the same Mersenne but math, physics, and compsci often overlap.
