| biography:
| Physicist, born in Beaugency, C France. A clerk with an interest in science, which led eventually to a chair in physics at Paris, he became famous by making the first manned ascent by hydrogen balloon, reaching 3000 m/9800 ft in 1783. His interest in gases subsequently led him to formulate Charles's law, which relates the volume of a gas at constant pressure to its temperature. |
