This man's efforts led to his country's adopting the metric system, and he was the first to rigorously enunciate the law of conservation of mass. His wife translated his work into English, and it was for her that he became a tax collector and gunpowder commissioner, for which he was guillotined during the French Revolution. Perhaps most famous for debunking the phlogiston theory, he also coined the name "oxygen" and also wrote the first general chemistry textbook. For ten points, name this Frenchman, considered the "father of modern chemistry."
