There are a ton of cultures and languages in Europe and because of a discussion the other day I realized that language is a big deal in getting a masters degree. I'm thinking German will be one language that I need to study but is there another language that is important like French or Italian. And also if anyone is interested I'm looking at becoming a museum curator and if there are any other tips you could give me like you did on the other post I would be very thankful. This is the discussion
French and German would likely do you the most good in a general way. Beyond that I suppose it would depend on your specialization. Latin could be very useful if you are working with a period that precedes the arrival of vernacular scholarship.
I am part of an Islamic Studies department and most of the researchers and professors have at least 3 languages under their belt. Arabic (classical and modern), Persian, French and German seem to be amongst the most accounted for in the department.
German is almost always going to serve you well, because you're guaranteed to find German historians writing important works about most topics in European history. Beyond that, it depends on what region you want to specialize in. If you're doing anything medieval, you'll definitely want Latin. Beyond that, things start to break down along regional lines. If you're studying western Europe you should learn French, studying Poland learn Polish (etc).
What specific time and region of Europe are you most interested in?
Pop over to /r/MuseumPros to talk to curators. :)
A friend of mine who did European History (And incidentally, is a museum professional) has French, Old French, Italian, Old Italian, Greek, and Latin as her languages, though generally reading far more than speaking for most of them. Latin will be extremely useful in particular, depending on how far back in history you want to go, as most of western Europe spoke it at some point.
There's another good discussion that a bunch of museum folks chipped in on over here, about education and career paths in museums.
If you're wanting to be a full-on curator at a major museum, you're likely going to need your Ph.D in your subject field. There are many other positions in museums other than curator (which I mention because many folks don't realize that, and I'm not sure how far along your career investigation you are), many of which will be accessible with an MA in Museum Studies or a related topic, on top of your BA in a specific interest.
A worthwhile thing to note about the museum career path is that it is extremely connection-based. That is to say, knowing people and having worked places is the best way to find out about jobs, get references, and have the opportunity to work more places. Internships are perhaps more productive here than in most other fields, so work hard and when the time comes, lay it on the line to get the internships you really want - they will help.
