I wrote my first (well, only) book in SGML Docbook, which I processed through a LaTeX toolchain. Sebastian Rahtz answered so many of my questions back then (~15 years ago), despite them often being stupid questions (because I was entirely new to TeX/LaTeX). I just read that he passed away last year. TeX Live was originally his project, among many other document-related projects. I'm happy to see it continues without him.
