Linus Torvalds
1969–
Linux Foundation fellow · creator of Linux and Git
Gave us
Linux (1991). Git (2005, written in 10 days because BitKeeper revoked Linux's license).
The story
Two pieces of infrastructure that hold up most of computing — both written as personal projects. Famously direct on the kernel mailing list; mellowed considerably after a 2018 self-imposed sabbatical.
One more thing
Wrote Git in ten days. Named it after himself ("git" being British slang for an unpleasant person).
