Which books do you recommend me to read for learning German and Russian for the sole purpose of reading mathematical papers that were written in these languages?
I believe that such a skill will be worthwhile not only for mathematical purposes.

The French publisher Assimil is very good (and famous) to get conversational skills in many foreign languages. As for the mathematical words, you can use Wikipedia, that's how I got to know that the German word for 'conjecture' was Vermutung. I guess you can easily find 'German with ease' or 'Russian with ease' on the internet. If you're mainly interested in reading, it's not necessary to buy the complete pack with CD's, which is rather expensive (around 70€ in France).
There is also the book Mathemecum of Joseph Maurer.
The book is in German and contains a collection of mathematical theorems and the names of the theorems are also given in English and in French; so that could help in learning the German names of certain theorems and maybe it is also good for training to read German mathematical texts.
