Who was F. Leonard Dunn?

Every time I jog around Centennial Lake, I always notice the F. Leonard Dunn Amphitheater and wonder who the person was that this amphitheater is named after (until I forget all about it 10 seconds later).

A quick Google search turned up nothing, so can anyone out there in the interwebs tell me who F. Leonard Dunn was (or is) and/or what he did?

Update June 2: FAIL. I am surprised there is no one who can or no one who is willing to shed light on this. A search of the Balt Sun archives suggests that maybe he was a council person in the 1970's? There is no historical list of HoCo council people (shows where they rate, I guess) so I will just be left to wonder.
