6th period

in the beginning
In the beginning…
  • Born on Feb. 29th, 1860
  • Born in Buffalo, New York
  • His family originated from Germany
  • He had 5 other siblings
  • 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
  • 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
the bright idea
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.
the use of the tabulating m achine
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!
advances since then
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
