Isaac Asimov's novels did have strong women, sometimes stronger than the men. Susan Calvin of I, Robot, was the smartest, coldest girl around. She was a nice lady and very intelligent The Mayor of Terminus from Foundation's Edge was also very intelligent, and a good political leader. Bayta from Foundation and Empire was innovative, smart and was able to save the day in the end. Arcadia from Second Foundation was a very smart little girl who went on an adventure. Dors from Prelude to Foundation, and Forward the Foundation was a body guard, a teacher and a pretty smart lady who saved the day. Bliss from Foundation's Edge and Foundation and Earth had a whole lot of power as well as brains and common sense as well as kindness. So to wrap up Asimov made many strong women in his science fiction novels. I should mention that some of them were made in the 50s and they showed strong women. Others were written later on.
