Back in the day, we chemistry students at the University of Minnesota were encouraged to take German and French in preparation for language exams in grad school. I did and, yes, took and passed language exams at Princeton and used my reading knowledge in reading the relevant literature. Alas, within a few years, the journals in those languages went to translating the abstracts into English and eventually the entire journal. However, I never regret taking those language courses.
