Antoine Lavoisier is deservedly considered one of the great chemists in history. We might not know of his experiments if it weren’t for his wife. She became a remarkable, if unconventional, chemist herself and had one of the weirder lives in history.
Pretty incredible how far science has come in 250 years, such a short span of time compared to the entirety of human history. We went from not even know what oxygen is to using it to fling stuff into space.
