A type of Jacquard card for silk weaving. Engraving by G. Gladwin after C. Varley. The mechanical Jacquard loom was a device for weaving textiles invented in 1804 by the French weaver and inventor Joseph Marie Jacquard (1752-1834). It had a number of novel design features and was the first to be automatically controlled. It was controlled by a number of perforated cards, the holes corresponding to the weave pattern. When the loom was introduced into factories, there were riots among workers who feared losing their jobs.
