Not quite the same thing, but I've always been struck by Ranulph Fiennes's personality and how perfect it seems for the kind of expeditions he did. He is the complete opposite of a drama-lama, he seems incredibly even tempered and stoic about everything. The same goes for Elen MacArthur, the round the world solo sailer. This seems like an essential characteristic of a successful explorer, you don't want drama, argument or emotional instability in places like the arctic.

This is how Apsley Cherry-Garrard, in The Worst Journey in the World, his account of the Terra Nova expedition, described leader Captain Scott.

Temperamentally he was a weak man, and might very easily have been an irritable autocrat. As it was he had moods and depressions which might last for weeks, and of these there is ample evidence in his diary. The man with the nerves gets things done, but sometimes he has a terrible time in doing them. He cried more easily than any man I have ever known.
