The possibility remained that the axioms of ZFC would be enough to establish the continuum hypothesis as true, but Gödel for one did not expect this.

What does "for one" mean in this context? The meaning of the sentence would be perfectly clear to me if "for one" were omitted. How do these words modify or amend its meaning?

Answer

For one ordinarily modifies the preceding NP. In practice it has much the same meaning as at least: that the NP is one entity occupying the particular syntactic/semantic role which the sentences assigns, and there may be other entities occupying that role.

I, for one, dislike the RNR construction. ... I dislike that construction, and there may be others who also dislike it.
I dislike the RNR construction, for one. ... I dislike that construction, and I may dislike others as well.

The phrase is always ‘parenthetical’: it’s really a shorthand way of qualifying your implication without making a big deal of explaining the qualification. In your sentence, for instance, the author is just making sure that we do not understand his particular notice of Gödel's response to this possibility as an indication that Gödel was the only mathematician who did not expect this result.
