inventor, used an idea similar to Jacquard’s loom when he
combined the use of punched cards with devices that created
and electronically read the cards. Hollerith’s tabulator was
used for the 1890 U.S. census, and it made the computational time three
to four times shorter than the time previously needed for hand
counts. Hollerith’s Tabulating Machine Company eventually
merged with other companies in 1924 to become IBM.
