The craziest one to me is still that Fridtjof Nansen's main sidekick in helping Armenian refugees was .... Vidkun Quisling.

It's not so surprising. Nansen was conservative-ish politically. Seeing the effects of the famine in Ukraine radicalized Quisling as a fanatical anti-socialist. He also married a Ukrainian woman (bigamously, but that's another story). As a fanatical anti-socialist in the 20s-30s he fell in with the wrong crowd.

Who knows if Nansen too would have, if he had lived to see the rise of Hitler. Probably not, as he was usually fairly ambivalent about politics, but it wouldn't have been terribly surprising either.
