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.

This morning i turned the pc on, booted ok, but freezed withing a few seconds.
Couldnt even do anything with ttys, freezed as well. But at least there i was able to see some messages before a total freeze: Out of memory: kill process.
So i restarted again and quickly opened system monitor: 4700 processes and my 4GB of RAM full after a few seconds. Then the freeze.
I booted in recovery mode, and then i run "/etc/rc.d/kdm start"
This way everything goes normal everytime. Normal boot leads to memory leak situation.

I didnt have much time to look but with top it looked like there was several instances of plasma desktop, every one of them consuming lots of ram.
