Day 1: First person who introduced you to D & D. 
The Baroness in 1991 at her restaurant on a slow Saturday morning. The adventure was about a giant and a magic cauldron. I played a fighter because it was the easiest to learn. My first encounter was on the road at night with hobgoblin bandits. 

Which edition? 
2nd Edition Dungeons and Dragons

Your first character?
Sir Nogoodnik a first level 1/2 eleven fighter. I seem to remember playing him as a arrogant and rather confused knight. He survived three games and then he retired with the gold he gained from adventuring.
