Sie ist ein wandelndes Lexikon.

Sometimes also used in this form

Sie ist ein lebendes Lexikon.

+1 for wandelndes Lexikon (I've never lived in a region where the other version is used). – Hendrik Vogt Aug 27 '11 at 13:49

One option would be "der/die Universalgelehrte" from the English word "polymath".

I think both Alleskönner and Tausendsassa could fit as well, if a more colloquial term is needed. Multitalent would be another option.

The word I would use is "savant." It was originally French, may have been adopted in German, but I'm not sure.

It is sometimes used in German, but only for who are "savant" due to Asperger syndrome, as far as I know. – Hendrik Vogt Aug 29 '11 at 17:47
I suspect a lot of Germans wouldn't be familiar with that term. I've certainly never heard it used. – Cass Aug 30 '11 at 13:35
You can use that (the german word is "Inselbegabter"), but it doesn't describe someone with a broad knowledge. Savants are often mentally retarded, but have one particular skill that is far better than that of normal people. That can be perfectly playing music just after hearing a piece once or reciting a telephone book after reading it once. A savant is also not necessarily an autistic person. – Katja Hahn Sep 6 '11 at 11:32
