Filling Hydrogen Balloon, 1783
Jacques Alexandre Cesar Charles (November 12, 1746 - April 7, 1823) was a French inventor, scientist, mathematician, and balloonist. Charles conceived the idea that hydrogen would be a suitable lifting agent for balloons having studied Robert Boyle, whose work was published 100 years earlier, and of his contemporaries Henry Cavendish, Joseph Black and Tiberius Cavallo. He designed the craft and then worked in conjunction with the Robert brothers, Anne-Jean and Nicolas-Louis, to build it in their workshop at the Place des Victoires in Paris. The brothers invented a methodology for a lightweight, airtight gas bag by dissolving rubber in a solution of turpentine and varnishing the sheets of silk that were stitched together to make the main envelope.
