The British scientist Henry Cavendish had discovered hydrogen in 1766 by adding sulfuric acid to iron, tin, or zinc shavings.

The development of gas balloons proceeds almost in parallel with the work of the Montgolfiers.

This work is led by French physicist Jacques Charles and les Frères Robert (Anne-Jean Robert, and Nicolas-Louis Robert).

On August 27, 1783, their hydrogen balloon is launched from the Champ de Mars in Paris.
