World’s first Statistical Engineer
He was known as the “Father of Information Processing”
Created an invention to tabulate the census that made it possible to complete
a census in a reasonable time frame and to collect other forms of data
His machine was based on the Hole Punch System which was based on
Jacquard’s hole punch system.(Jacquard used his hole punch system to weave
patterns into cloth)
In 1889 his machine was used for the Twelfth Census and it only took 6
weeks. (That is a fra
ction of the time it took to take previous census.)
His machine saved the Census Bureau about $5,000,000
In 1911 his company, called tabulating Machine Company, merged with 2
other companies and created the Computing
any changed names in 1924 to International Business Machines
(IBM) under Thomas Watson.
Hollerith’s machine was the basis of IBM’s success.
Created the Jacquard Loom
a Loom to weave patterns in cloth.
The Jacquard Loom uses stiff cards
with patterns of punched holes that program
the loom to weave on cloth and carpets.
Jacquard changed the weaving industry and inspired the use of punch cards.
By 1812 there were 11,000 looms in use.
The loom increased productivity and reduced the cost of
Today computers use the same binary on and off coding.
The loom caused riots by people who were against replacing human jobs with
Punch cards were used in the first design of calculators and programmed
computers of the 12
Was awarded the Nobel Prize in Physics in 1956 for his

phones, and modern electronics. It is a small switch that controls the passage of
electricity. It replaces the large va
