Pauli was not just hurt by the fact that his marriage had come apart - he jokingly referred to being married only in a "loose way" - but by his bride's choice of man. Deppner had left him for a chemist, of all things, and not even a good one. Pauli loudly complained to his friends, "Had she taken a bullfighter I would have understood - with such a man I could not compete - but a chemist - such an average chemist!" [Bold emphasis added]
I heard this quote in Prof. George Whitesides's talk titled "Reinventing Chemistry" at IISc two years ago; it's nice to get the back story with names (if you are impatient, go to 28:45 in the video).
