Herman did much more than "punching holes in sheets of paper". He devised a machine that could take those holes and count them ("tabulate" was the term used, and the "tabulating machine" came from that). He also *standardized* on a size for these sheets of paper, making them the same size as the dollar bills of that time. Why? Because he knew he could easily get lots of storage racks for dollar bill sized cards from the suppliers of banks, who used them to store money. Later (of course) the government changed the size of the dollar bill, making it smaller.
He also identified ways of coding the complex information onto the cards.
And while the holes punched into the player piano rolls and Jacquard loom were actually "control signals", the Hollerith card information was actually "data", which were accumulated and controlled by the way the tabulating machines were set up. This distinction is subtle, but important, and was the real breakthrough for Hollerith.

One and the same, Jody, one and the same.
