Tourists

A group of American tourists was being guided through an ancient castle in Europe.

"This place," the guide told them, "is 600 years old. Not a stone in it has been touched, nothing altered, nothing replaced in all those years."

"Wow," said one woman dryly, "they must have the same landlord I have."

Antoine-Laurent Lavoisier

Born 26 Aug 1743; died 8 May 1794 at age 50. French chemist, the “father of modern chemistry,” was a brilliant experimenter also active in public affairs. An aristocrat, he invested in a private company hired by the government to collect taxes. With his wealth he built a large laboratory. In 1778, he found that air consists of a mixture of two gases which he called oxygen and nitrogen. By studying the role of oxygen in combustion, he replaced the phlogiston theory. Lavoisier also discovered the law of conservation of mass and devised the modern method of naming compounds, which replaced the older nonsystematic method. During the French Revolution, for his involvement with tax-collecting, he was guillotined.
