Herman Hollerith (1860-1929), wrote a doctoral dissertation at Columbia University on his own tabulating system. He later developed this punched card tabulating equipment, which revolutionised the tabulating of statistics for the United States Census Bureau in 1880. This development, born from watching a train conductor punch tickets, saved the Bureau $5 million. The technology was used up to the late 1970s, and was the nucleus of today’s computing industry
Hollerith founded the Tabulating Machine Company in 1896, which, 28 years later, after several take-overs, became International Business Machines, or, as it is better known, IBM.
