Important people in Computer Science

List the names of important people in Computer Science and their contributions to the field. I will start.

Grace Hopper - She built the first compiler named A-0. She is credited with popularizing the term debugging, because she found a real bug (a moth) stuck in a relay therefore impeding the system.

I would have been in the top 100 most important people in computer science. However, my Jewish professor took credit for my doctoral work and conspired to discredit my name in front of an ethics review board, resulting in all of my credentials being revoked and me being kicked out of university. These days, I pack fudge at a local cannery down by the docks to make a living.
