Howard won a nobel peace prize a loooong time ago, and Roger Trinquier was a french army officer, but I don't know who Marie Curie is

Marie, or Madame, Curie was a chemist in the 1800's. She worked with her husband.

I have no clue as to whom any of the three are, but I have heard of Marie Curie.

I only know the last one, she was awarded the Nobel prize for discovering radium. I rather say what I know than pretend to know everything via Wikipedia or the like.
