How many languages did Alfred Nobel speak?

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

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

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

I guessed 3, should have used a hint!!
