The Jacquard loom is a mechanical loom, invented by Joseph Marie Jacquard, first demonstrated in 1801, that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelasse.
The loom is controlled by a "chain of cards", a number of punched cards, laced together into a continuous sequence. Multiple rows of holes are punched on each card, with one complete card corresponding to one row of the design. Chains, like Bouchon's earlier use of paper tape, allow sequences of any length to be constructed, not limited by the size of a card.
It is based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740).
The Jacquard head used replaceable punched cards to control a sequence of operations. It is considered an important step in the history of computing hardware. The ability to change the pattern of the loom's weave by simply changing cards was an important conceptual precursor to the development of computer programming and data entry.
Charles Babbage knew of Jacquard looms and planned to use cards to store programs in his Analytical engine.
In the late 19th century, Herman Hollerith took the idea of using punched cards to store information a step further when he created a punched card tabulating machine which he used to input data for the 1890 U.S. Census.
Punched cards remained in use in computing up until the mid 1980s.
