Antoine Lavoisier and the Musee des Arts et Metiers

Antoine Lavoisier was one of the founders of chemistry. His work demonstrated the idea of "stoichiometry", that chemical compounds react in particular ratios. He's rightly enshrined as a hero of chemistry, and you can see his equipment in the excellent Musee des Arts et Metiers in Paris:



It's a great museum of science, with all sorts of interesting hardware from different eras.



It also had some historical technological figures of a different type during my visit, as part of a temporary exhibition.



As for Lavoisier, he was executed during the Terror, but is remembered with justifiable  pride by his countrymen. Look closely, and you can find his name on the Eiffel Tower.
