His mother? :-/
I read that Dinah was far more urbane, sophisticated and educated than Burt and he became her ‘pupil’ more or less- taught him how to get along with the ‘upper crust’, etc.
Both declared that there was love there also, though.
They never married because of the age difference. (Dinah’s decision)
True, he may have been looking for a mother figure in the beginning.
I was never a Dinah fan, but she was a big deal in her day.
