Hedde was a textile manufacturer and director of the Industrial Museum of St.-Etienne. In an address delivered before the 24th session of the Congrès scientifique de France (no.  above), Hedde argued that it was Jacques Vaucanson (1709-82), rather than Joseph-Marie Jacquard (1752-1834), who should be recognized as the true inventor of the automatic weaving loom. Vaucanson, a famous designer of automata, designed and built the first fully automated loom in 1745, using a system of punched cards to create intricate designs. Vaucanson’s automated loom was not successful, but half a century later Jacquard came across an example in the Musée des Arts et Métiers and was inspired to improve upon Vaucanson’s design, inventing the automated loom that now bears his name. Both Vaucanson’s and Jacquard’s punched-card looms are now recognized as ancestors of computing technology. Hedde’s second manuscript (no.  above) contains additions to his 1857 address as well as an explanatory letter addressed to the president of the Congrès scientifique de France.Book Id: 44812
