Mike Mastandrea
One of the "founders of the National Academic Association," along with Chip Beall and Brick Barrientos, according to the Questions Unlimited website. He is still a moderator and "chief judge" at the NAC.
The QU site claims that Mastandrea invented the sixty-second round. This is probably not true, given that timed rounds were a staple of the first two decades of It's Academic (1961).
