Carl Worth was the original author of Notmuch. David Bremner has maintained Notmuch since release 0.6 (2011). But there's really not much that they've done. There's been a lot of standing on shoulders here: William Morgan deserves credit for providing the primary inspiration for Notmuch with his program Sup (https://sup-heliotrope.github.io/). Some people have contributed code that has made it into Notmuch without their specific knowledge (but with their full permission thanks to the GNU General Public License). This includes: Brian Gladman (with Mikhail Gusarov ) Implementation of SHA-1 (nice and small) (libsha1.c) Please see the various files in the Notmuch distribution for individual copyright statements. And of course, though their code isn't distributed here, Notmuch would be not much of anything without the contributors to Xapian, the search engine that does the really heavy lifting, as well as the various system libraries, compilers, and the kernel that make it all work (thanks GNU, thanks Linux). Thanks to everyone who has played a part! The following list of people have at least 15 lines of code in the Notmuch 0.31 release (calculated by devel/author-scan.sh).
