Inge Lehmann (1888-1993) Discovered Earth'S Inner Core In Her Free Time

Very recommendable! Besides the famous Marie Curie there were other trailblazing early (sometimes unmarried) female scientists!

"... Lehmann once complained to her nephew Niels Groes about the incompetence of her male colleagues, and wrote him: "You should know how many incompetent men I had to compete with—in vain." ..." (Wikipedia)

"... Her parents believed that boys and girls should have the same education ..."

Caveat: I did not read the whole article!
