Gave us
Python. The language is named after Monty Python, not the snake.
The story
Built Python over Christmas break in 1989. Stepped down as BDFL in 2018 after the walrus operator (PEP 572) debate burned him out. Returned to active dev at Microsoft on CPython performance.
One more thing
BDFL stood for "Benevolent Dictator For Life". The "for life" part was negotiable.
