  1. Herman Hollerith Tiffany Roberts 6th period

  2. Visual Aid…

  3. In the beginning… • Born on Feb. 29th, 1860 • Born in Buffalo, New York • His family originated from Germany • He had 5 other siblings

  4. Education • He started New York City College at the young age of 15 • Tutored privately by his church pastor • He went to the Columbia School of Mines studying engineering • he took chemistry, physics, and geometry… all the classes we love so much…  • He graduated with his degree from Columbia School of Mines at the age of 19

  5. Jobs • Started a jobs at the U.S. Census Bureau • It took a ten year period census to be completed • 7 years at a time a census was finally completed and the next thing you know, it was time to do it again

  6. The Bright Idea • His co worker’s father, Dr. John Shaw Billings , also a worker for the U.S. Census, made a comment to Hollerith that there should be a mechanical machine to do the work with to make it easier. • This sparked the idea of the tabulating machine.

  7. The Tabulating Machine and Punch cards

  8. The use of the Tabulating Machine • Because the cards that Hollerith used at first were too thin and easy to tear, he used the design of Jacquard’s punch cards. (length of a dollar bill and a light cardboard material) • The tabulator operated using nails, cups half-filled with mercury, and spring-actuated points. After the card was punched with data about a person, it was placed into the tabulator on a reader station. A lid was closed over the card. Wherever one of the points found a hole, it would stick down into the mercury and close an electric connection. Each electrical connection was registered on a dial that functioned as a counter, making his job easier and faster than ever!

  9. Advances since then … • Because of his machine, more information was processed and more could be done • Later on, magnetic tape took over the punch cards and an operator would enter information that would be stored directly onto the tape. • Even further, IBM created diskettes which aloud information to be stored compacted( in a smaller space, take up less room) • Many more advances has been made since then but because of something he created opened up a larger door to success and technology
