I’ve read the Alfred Lansing book, “Endurance”, and until its publication in 1959 Shackleton was largely forgotten. That book led to his deserved revival. I regard it as one of the two best books ever published on antarctic exploration, the other being “The Last Place on Earth” by Roland Huntford. It was PBS series of the same name that got me hooked on antarctic polar exploration 35 years ago.
I cannot agree more that this should be taught in schools.
The events of WWI cast a shadow over Shackleton’s feat.
