A biographical article on Joseph Marie Jacquard (1752-1834) and the invention of the Jacquard loom. It covers his life in Lyons, his early drawboy machine and prizes, the hostility of the weavers, and his later honors. It also discusses his forerunners Falcon and Vaucanson, quotes an 1808 description of the card-controlled hook and griffe mechanism, and ends with the loom's worldwide spread. Illustrations include a portrait plate, a mechanism diagram, and a foot-pedal Jacquard loom from the 1840s.
