Comment Reminder: Alan Turing year (Score 2) 57
While probably somewhat known among Slashdotters, I think it is worthwhile to remind people of Alan Turing, mathematician, logician, WWII code breaker and father of computer science (as well as being a victim of cruel injustice by the state).
He's unfortunately by far less recognized than people like Steve Jobs (probably because turing machines don't have rounded corners by design). It's a bit like the story of Tesla vs. Edison. One was a genius scientist, the other one an asshat making lots of money, without contributing nearly as much to the field, but still being more famous and celebrated.
