>They had a language requirement for a math PhD. To get a PhD you had to either be fluent in one of French, German, or Russian, or you had to have a sufficient reading ability in two of those to read the current and historical math literature in those languages.
This a thing of the past, from a time when people in the USSR still published things of note in Russian (the same for the other countries/languages your mentioned). Today everyone publishes in English and I don't of a single math department that still has that as a requirement.
I also don't know of any other such extracurricular requirements for any program (can't even imagine what it would be - community service???)
Hmm must be the last (leave it to Harvard to persist in the persist in the pretence I guess) but fwiw this is the entirety of the task:
>Students may request to substitute the Italian language exam if it is relevant to their area of mathematics
Which is far far short of "learn a language". But these requirements were always like this (a pretentious formality completely insignificant in comparison to the actual research and course work).
