"In Pauli’s letters to von Franz, he admits that they had a “crush” on one another, although von Franz denies this. Unfortunately his wife, who considered Pauli’s intense interest in dreams a frivolity, was so distressed over the possibility that his reputation as a physicist might be damaged by his interest in Jungian psychology, that she burned a box of letters from Marie-Louise von Franz after Pauli died."
