11. Heinlein was married three times.
His first wife was named Elinor Curry. Not much is known about her, and their marriage lasted only about a year. Before leaving the Navy, Heinlein married Leslyn MacDonald. She was intelligent, well read and very liberal. Their marriage was ultimately unsuccessful, but it lasted for well over a decade. He was married to his third wife, Virginia, (nee Gerstenfeld), until he died in 1988.
It is believed many of his early heroines resemble Leslyn. Perhaps so, but perhaps Heinlein just liked multi-competent females. Having been privileged to speak to the third Mrs. Heinlein, I can attest she was intimidatingly intelligent and well read, and that I found her echo in many of his female characters. So much for everyone who claims that his women are men with breasts. (Whether he had a male’s naïve view of female sexuality is a wholly different matter. To a certain extent, try as we might, we are all prisoners of that space behind our eyes, and no matter how much talented individuals try to escape it, they’re prone to believing what others wish them to believe.)
