So: In 1964 GR writes his main female character without a personal name, referring to her with a numerical code that implies superiority. She is all cold and unfeeling. THEN he marries the actress he hired to portray her and casts her as nurse: the nurturing, mothering profession of all time -- and gives her a religious name. Then writes her a part as a domineering mother (stereotypical mother-in-law) twenty years later; and uses her as the voice of ultra-reason and intelligence, the computer.
GR married Barrett in 1969, when the show had already been cancelled.
