You are looking at it from you perspective as presumably someone without a mental illness. If you suspend disbelief and consider the possibility of mental illness none of this is remarkable or surprising. Usually the simplest explanation is the correct one. You also are assuming her work was head and shoulders above the work of her contemporaries. I have seen no evidence of that. You are also assuming she is the sort of person who gets hired to do one job and uses that "in" as a way to push her portfolio. A lot of people particularly back then wouldn't be inclined to do something like that.
