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 tabulating machine and punch cards
The Tabulating Machine and Punch cards

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
