These people have programming languages named after them:
- Haskell B. Curry (Haskell) (who also got currying, not of favour)
- Blaise Pascal (Pascal)
- Ada Lovelace (Ada)
- Alfred Aho, Peter Weinberger, and Brian Kernighan (awk)
- Alan Turing. Besides the machine, WaldemarExkul informs me that University of Toronto had a language by this name -- "essentially Pascal without the semicolons" required, it has a grab-bag of add-ons.
- Erlang, after the mathematician Agner Erlang -- inventor of the Erlang numbers, aka "why can't I get a cellphone line when I'm at a 250,000 person demonstration?!"
- Gödel: origin is obvious (http://www.cs.bris.ac.uk/~bowers/goedel.html) (but the language apparently somewhat less so...)
- Pike, after the fish (fish are people too).
- Occam, the language of the ill-fated Transputer chip, used mainly by parallelized weirdos -- William of Ockham
On the other hand, none of these associations has any basis in fact:
This lot really do have programming languages named after them, but they're not really people:
randombit added around 56 languages to the above list.
