The Hollerith Machine was an early data processing device invented by Herman Hollerith in the late 19th century. It used punched cards to store and process information, significantly speeding up the analysis of large datasets. This machine was notably used in the 1890 U.S. Census, helping to reduce the time required for data compilation from years to just months. Hollerith's invention laid the groundwork for modern computing and data processing. His company eventually became part of IBM, which further developed the technology. The Hollerith Machine marked a pivotal moment in the evolution of information technology and data management.
