At a conference this week in the northern Netherlands this week to celebrate a professor's retirement- and the speaker just said about him and the retiree, "and back then, of course, we were working for Oort in Leiden..."
Wait, THAT Oort?!
Not like Dutch astronomy is a huge community so guess overlap is expected amongst bigwigs, but still, I thought that was neat. (Also note for those who aren't aware, Oort was actually a famous radio astronomer in his day- it's kind of an odd twist that he's now most famous for something completely out of his field, in proposing the Oort cloud.)
