Note from Manu:

I found the story I was thinking about: Reed Hastings founded the company that built the Purify tool for debugging memory errors in C programs before founding Netflix. But, that’s actually not a static analysis tool; it does dynamic analysis by adding extra metadata at runtime.

As far as the history of lint goes, from Wikipedia looks like Kaushik’s guess was exactly right as to why it’s called lint. Looks like the name goes back to the late 1970s.
