Is there a website or something where I can find who all the past National Commanders were and perhaps a bio and/or photo?
Try the CAP History link from the NHQ site, or Google on "CAP history".
It's also on Wikipedia.

What are you looking for? I thought about making framed photos of all the past commanders for the cadet office. I thought it might be neat for them to see the past leaders, uniform changes, etc.
