Joseph-Marie Jacquard presents in Lyon the loom programmable via punched cards, patented in 1804. The system encodes weaving patterns on cardboard cards with holes controlling which threads are raised on each pass, allowing complex designs to be reproduced automatically without manual intervention on each cycle. Napoleon Bonaparte declared it public property, and Jacquard received a pension and royalties. The principle of instruction via punched cards was adopted directly by Charles Babbage in the design of his Analytical Engine (1837) and later by Herman Hollerith for the US census (1890), becoming the conceptual foundation of programming via external instructions. Both Charles Babbage (Analytical Engine, 1837) and Herman Hollerith (tabulator, 1890) derived from Jacquard's principle independently and with no documented contact between them: Babbage applied it to complex mathematical calculation via instructions; Hollerith applied it to mass statistical classification, further inspired by train conductors who punched tickets to record passengers' physical traits.
