When did Joseph Marie Jacquard refine the mechanical use of punched cards for loom control?
Answer
Around 1801
The foundational concept for using punched cards to dictate an action began with the Jacquard loom predecessor introduced in 1725. However, the specific refinement that allowed weavers to reproduce intricate patterns automatically and consistently was achieved by Joseph Marie Jacquard. He solidified this control mechanism around the year 1801. This refined system demonstrated the viability of stored program control by using the sequence of holes on the cards as the specific instructions for the loom's mechanical operations.
