Ask HN: The Best Programmers' you've ever read

In my free time, I try to read the source code of projects I think are interesting, and in the course of my years I've found some programmers I've really come to respect. I was wondering if you guys would be willing to list out the programmer(s), and their projects whose source code helped you learn and become better developers? For instance here's a quick list of guys who've influenced my programming and whose source code has taught me lot:

Javascript: - Jeremy Ashkenas: Backbone, CoffeeScript - John Resig: jQuery

PHP: - Fabien Potencier: Symfony2 - Leo Feyer: Contao - Kasper Skårhøj: Typo3

C: - Salvatore Sanfilippo: Redis
