The wives and families of famous adventurers are rarely mentioned or considered, but I think their hardships and mental endurance may equal and sometimes surpass that of their more famous relatives. Lotte's mother, Else Wegener, must have suffered considerable anguish both while her husband was making his important discoveries in Greenland, and also when she was eventually widowed at an early age with three young children (and two elderly parents). Then within a couple of years her eldest daughter, Hilde, died too, which must have been extremely hard to bear. When just a few years later her youngest daughter married another risk-taker and she had to help look after yet more (temporarily) fatherless children she must have pondered on the tendency of history to repeat itself.
Else Wegener was an accomplished writer and translator of books herself and wrote two interesting biographies of her husband and her father, Vladimir Köppen, who was an eminent meteorologist. She also helped her husband in some of his work, for instance interpreting the dialect of local people for her husband when he was interviewing them - he used their reports to predict where a meteorite had impacted.
When Heinrich Harrer returned from Tibet she was in her fifties, and I hope that from then on her life was easier. As it turned out she had many years to go and only died fairly recently - in the early 1990s aged 100.
