Claude-François-Dorothée, marquis de Jouffroy d'Abbans

Claude-François-Dorothée, marquis de Jouffrey d'Abbans (1751–1832) is claimed to be the first inventor of the steamboat.

In 1773, Jouffroy d'Abbans met with the Perier brothers and studied in their workshop the Pompe à feu (Fire pump), which had been used as a motive force for the hydraulic machine developed by Chaillot, in order to apply to ship propulsion.

In 1776, Jouffroy d'Abbans develop a 13 meter steamship, the Palmipède, in which the engine moved oars equipped with rotating blades. The ship sailed on the Doubs in June and July 1776.

Model of steamship, built in 1784 by Jouffroy d'Abbans, to convince Perier of his invention.

In 1783, he made a paddle steamer named the Pyroscaphe ply on the Saône in 1783. However the Académie des Sciences prohibited him from using his invention in Paris, and instead nominated Perier, one of d'Abbans' opponents whose previous attempts had failed, to inspect the project. Further misfortunes due to the French Revolution hindered his progress. His claim was acknowledged by Arago and in 1840 by the French Academy.New International Encyclopedia Jouffroy published Les bateaux à vapeur and wrote for the Academy Mémoires sur les pompes à feu. Impoverished, he retired to the Hôtel des Invalides and died there of cholera.

In 1803, more than 20 years after d'Abbans inaugural trip, Robert Fulton would succeed in sailing a steamship of his conception on the Seine.
