There is a mistake in the description, probably even the official Marie Curie aka Maria Skłodowska-Curie was Polish, she was born in Poland, she began her study in Poland, she worked in France. She named the element polonium, after Poland.

It's sad how history is forgotten, even in a show that's about history. Maybe Rittenhouse changed it ...
I will add a little-known fact that Poles broke Eniega first, which is almost never mentioned https://www.telegraph.co.uk/science/2016/03/15/polish-codebreakers-cracked-enigma-before-alan-turing/ http://www.dailymail.co.uk/sciencetech/article-3448817/How-Poles-cracked-Enigma-Turing-Country-launches-campaign-heroes-broke-code-1930s-recognised.html
I'm happy the show came back
