It's complicated; Calvin Rose was the original creator of Fennel ("fnl"), but I understand it was just a little side project that he made over the course of a week or so in college. Phil Hagelberg found the project years later and thought it was cool, took over as its maintainer, and basically turned it into the Fennel you know today. So it's like, kind of, I dunno, both things are kinda true.
