7 0

Explanation:

The standard punch card (for computers) was invented and developed by Herman Hollerith. But the idea of punch cards was already long invented, used to control Jacquard looms.

Jacquard looms were looms that used punch cards to control the pattern a loom weaves.

The idea of punch cards in Jacquard looms also influenced Charles Babbage, who decided to use punched cards to control the sequence of computations in his proposed analytical engine. Unlike Hollerith's cards of 50 years later, which were handled in decks like playing cards, Babbage's punched cards were to be strung together.
