Masterminds of Punched Card Data Processing: Herman Hollerith and John Billings

Herman Hollerith was an American inventor and engineer who played a significant role in the development of computing and information processing systems. He is best known for inventing the punched card tabulating machine, which was used for processing data and performing calculations. This invention laid the foundation for modern data processing and greatly influenced the development of early computers. Hollerith’s work eventually led to the formation of the company that would later become IBM. (Courtesy of ChatGPT.)
