Byron Johnson's reply mentions adding artifacts to the displays to add
context. They don't have to be actually from the person's life, but just
something to quickly place the person's role in the community.
Probably a little research will locate additional images to illustrate
the bios: news articles, photos of their homes and work, letters and
documents.
How much you put into this depends on the purpose of this "Hall of
Fame."  Are these the founders of your museum, or Anchorage pioneers, or
both? Is this an intro to the museum, a "thanks for all the money" wall,
or one of the main presentations?
