2  Born in Buffalo, New York on February 29,  Parents were immigrants to the US from Germany in  He was clever at an early age but hated his teacher correcting him.

3  Hollerith entered the City College of New York in  Became an engineer graduate of the Columbia School of Mines in  His exam scores were so high that his professor asked him if he would be his assistant.

4  Joined the U.S. census bureau as a statistician.  His job involved solving problems of analyzing the large amounts of data generated by the 1880 census.  Needed a way to make his job easier.

5  Herman Hollerith first got his idea for the punch-card tabulation machine from watching a train conductor punch tickets.  Dr. Shaw Billings gave him an idea for the tabulating machine. -He said… “There ought to be some mechanical way of doing this job, something on the principle of the Jacquard loom, whereby holes in a card regulate the pattern to be woven. “

6  He used metal pegs to punch through holes onto an electrical plate.  Each hole represented data.  The machine used electricity to sort data.

7  Before Herman Hollerith built the tabulating machine, the census took 7 years,  With the machine, the census took just 6 weeks.
