In the winter of 1974, the German filmmaker Werner Herzog walked from Munich to Paris in the hope that this would prevent the death of his friend, the film historian Lotte Eisner, who was seriously ill. “I set off…believing that she would stay alive if I came on foot.” It took Herzog three weeks to make the journey, and while it may be a coincidence, Eisner recovered and lived nine more years. Herzog’s account of the walk was published as Of Walking In Ice. In 2019, Herzog made a film about another walker, his friend and the author of The Songlines, Bruce Chatwin. Herzog talks about Chatwin and the importance of walking in this interview.
