http://en.wikipedia.org/wiki/List_of...versity_alumni
Not sure who created/upkeeps the website, but it's pretty cool to see. Looks like not everyone on the list is an "alumnus", as some only attend Tech for a short period then transferred to another school.
Most surprising on the list for me: Will Wright - Co-founder of the game development company Maxis; Creator of the Sim City computer game series
Missing from the list: Cheryl Ford, Dr. Randall F. Barron, and others (http://www.latech.edu/admissions/alumni.shtml)
