There are a lot of references like that, not even counting the numerous references to various science-fiction franchises. Whenever I don't recognize a name, it very frequently turns out to be significant in some way. I was not previously familiar with French chemist Henri Moissan, for example, or the ship-breaking yard in Gadani, Pakistan. (Still haven't figured out Vaccaro-Ibrahim, although the latter may refer to famous Sudanese genetecist Muntaser Ibrahim.) It's one of my favorite narrative features.
