Gough, Charles the Obscure, Isis 70, , pgs — Charles and the Robert brothers launched the world's first unmanned hydrogen -filled gas balloon in August ; then in December , Charles and his co-pilot Nicolas-Louis Robert ascended to a height of about 1, feet m in a manned gas balloon. Charles's law, describing how gases tend to expand when heated, was formulated by Joseph Louis Gay-Lussac in , but he credited it to unpublished work by Jacques Charles.

The English scientist Robert Boyle had many years earlier determined the inverse relationship between the volume V and pressure P of a gas when temperature T is held constant.
Charles did not publish the results of his work at the time, but another French scientist, Joseph-Louis Gay-Lussac, eventually learned of them. When Gay-Lussac did more extensive and precise experiments and published his similar findings in as did the English scientist John Dalton , he acknowledged Charles's original work. Thus, the law governing the thermal expansion of gases, although sometimes called Gay-Lussac's law, is more commonly known as Charles's law.
While most of Charles's papers were on mathematics, he was ultimately an avid scientist and inventor. He duplicated a number of experiments that Franklin and others had completed on electricity and designed several instruments, including a new type of hydrometer for measuring densities and a reflecting goniometer for measuring the angles of crystals.
He died in Paris on April 7, Toggle navigation. David A.
