A wall of expeditions

When I decided to compile my own list of greatest adventurers in response to Tarquin Cooper’s selection in The Telegraph I pondered briefly about criteria, categories etc. Then I decided instead to merely rattle off some of my heroes, in no order and with no justification.
Disagree with my choices? Have your say in the comments.
