Who is the most famous person you have ever spoken to?

This would be Fred Brooks (https://en.wikipedia.org/wiki/Fred_Brooks) of 'The Mythical Man-Month' fame (https://en.wikipedia.org/wiki/The_Mythical_Man-Month).

I was very lucky to be moderator in a very relaxed grad student seminar at my old uni when Fred was visiting Germany. It was truly awesome to hear him talk about the issues in software development practices, and his take on how to conduct oneself as an academic and developer.

(the book he signed for me is still one of my prized possessions )

I did a podcast for a bit with some buddies and we got a couple of voice actors from games on. Probably Erin Fitzgerald is the most famous.

Talked to a couple of the people who worked on Darkest Dungeon too. Wayne June, the VA for the Narrator, is a really interesting guy.

Talked to Peter Norvig after a presentation of him, and ended up having lunch with him and some other students.
