How many languages did Alfred Nobel speak?

777, french, german and russian, beside his own mothertongue swedish

stashio2020, very difficult question, but one I now know the answer to :)

777, it tells you very clearly in the answer

Apparently the story about him reading his own obituary has been proven to be a myth. source: Stephen Fry from QI

my grandfather spoke 8 languages. We didn't really appreciate it until he was elderly

I guessed 3, should have used a hint!!
