This is a stretch, but bear with me. Don Knuth saw that typesetting was being done wrong, and spent decades doing it right in his own idiosyncratic way, creating TeX. Terry Davis did the same with operating systems, creating TempleOS. Knuth's is the forgiving New Testament faith, while Davis's is the vengeful, capricious Old Testament one, but they were both driven by a personal faith and genius. Knuth's obsession was rewarded by society, while Davis's was scorned. Neither did any real harm.
