Jacques Alexandre César Charles was a French inventor, scientist, mathematician, and balloonist. Charles wrote almost nothing about mathematics, and most of what has been credited to him was due to mistaking him with another Jacques Charles, also a member of the Paris Academy of Sciences, entering on May 12, 1785. He was sometimes called Charles the Geometer. Charles and the Robert brothers launched the world's first unmanned hydrogen-filled gas balloon in August 1783; then in December 1783, Charles and his co-pilot Nicolas-Louis Robert ascended to a height of about 1,800 feet in a manned gas balloon. Their pioneering use of hydrogen for lift led to this type of balloon being named a Charlière. Charles's law, describing how gases tend to expand when heated, was formulated by Joseph Louis Gay-Lussac in 1802, but he credited it to unpublished work by Jacques Charles.

About Jacques Charles
French scientist, mathematician and inventor who launched the world's first hydrogen-filled balloon in 1783 and was the inspiration for Charles's law which describes how gases tend to expand when heated.
Jacques Charles Before Fame
He studied the work of Robert Boyle in the publication called Boyle's Law which was published in 1662.
Achievement of Jacques Charles
He invented several useful things including the valve that lets hydrogen out of a balloon.

Associations of Jacques Charles
Benjamin Franklin was one of the onlookers when he launched the first hydrogen filled balloon from the Champ de Mars in 1783.
