She died as a result of radioactive exposure over the years of her scientific research. Pour one out for Madame Curie.

Sorry-Einstein's Wife-The Other Einstein-by Marie Benedict

If you liked this, you might like the book about Einstein; Wife, The Other Einstein, who personally knew Marie Curie. Mileva Maric was possibly/probably responsible for what Einstein got the Nobel Prize for, but because she was a woman and from Serbia, no one paid attention. Curie's husband was huge in promoting his wife. He made sure she got the credit. There was a good man, especially in those days.
