Jacques Alexandre César Charles (12 November 1746 – 7 April 1823) 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 (sometimes called Charles the Geometer [1]), also a member of the Paris Academy of Sciences, entering on 12 May 1785.
Charles conceived the idea that hydrogen would be a suitable lifting agent for balloons because, as a chemist, he had studied the work of his contemporaries Henry Cavendish, Joseph Black and Tiberius Cavallo. [1] The balloon built by Jacques Charles and the Robert brothers is attacked by terrified villagers in Gonesse.

Charlière is the name used by French writers to refer to gas balloons [1].The Academy of Science commissioned Jacques Alexandre César Charles to build balloons in the summer of 1783 because the court of King Louis XVI did not want to wait that long before the Montgolfier brothers finally came from Annonay with their invention called Montgolfière.

"The Vitruvian Man" by Leonardo da Vinci. Many Catholics have made significant contributions to the development of science and mathematics from the Middle Ages to today. These scientists include Galileo Galilei, René Descartes, Louis Pasteur, Blaise Pascal, André-Marie Ampère, Charles-Augustin de Coulomb, Pierre de Fermat, Antoine Laurent Lavoisier, Alessandro Volta, Augustin-Louis Cauchy ...
Despite these limitations, there was support for women in the sciences among some men, and many made valuable contributions to science during the 18th century. Two notable women who managed to participate in formal institutions were Laura Bassi and the Russian Princess Yekaterina Dashkova. Bassi was an Italian physicist who received a PhD from ...
