Jacquard used them first in his loom. Hollerith borrowed the idea for his
tabulating machines. Hollerith's company turned into IBM, which used them
extensively for programming. So Hollerith invented them for use in
programming counting machines, which is why she perhaps attributed the
invention to him. But in fact, Jacquard was the first to use them in
machinery.
