There are a few activities that I consider “must-dos” whenever I visit a museum, but my boyfriend (a huge trooper who has accompanied me to over 50 museums in the last four years) only has one thing that he cares to do during a visit: Check out the donor wall. In Seattle, I thought it was just to see if Jeff Bezos had given away any money yet (and his company eventually did). But Ian checks everywhere. While standing in front of the donor wall at the first 45 or so museums with him, I thought something like, “Yes, yes. The donor wall lends credibility to the museum.” But when the Bill Gates Giving Pledge was announced in August of this year, it changed the way that I think about the donor wall.
