Jun 11, 2024 · Herman Hollerith (1860–1928) recognized this problem and developed the Hollerith Tabulating Machine using punch cards, which reduced the analysis from 10 years to 3 months. This machine allowed researchers to spend more time analyzing the impact of the data instead of the enormous time taken to collect and then tabulate the data.
