Some areas of the humanities aren't settled on English as their only language. I gather that Egyptologists find it extremely convenient (bordering on necessary) to be able to read modern French and German, which are the languages of important Egyptology journals and books. After that Arabic wouldn't hurt, and I'd guess Russian would be nice (less certain on that one). That's in addition to the languages of their primary and contemporary secondary sources, mind you, which are very important but not used to write up new research :-) Likewise those studying the history or politics of many other regions are aided by knowing French or German or both, plus local and historical languages obviously. In at least some sub-fields of philosophy I'd expect French, and maybe other languages, to be practically a requirement for keeping up with new work and developments. Many native English-speaking economists and political scientists likely did benefit or could have benefited from being able to read French for Piketty's book, which didn't reach the English language until months later. I don't know what effects, positive or negative, this has on the people who work in those fields.
