What was the computer invented by Herman Hollerith?
the punched card machineHerman Hollerith is the father of modern machine data processing. His invention of the punched card machine marked the beginning of the automatic data processing age. Whereas punched cards had previously been used to control looms, Hollerith now used them to store data.
When was Hollerith invented?
Herman Hollerith (1860–1929), an American engineer and inventor, made a major breakthrough that paved the way for the invention of the modern digital computer. He invented a punch-card system in 1890, first used widely by the federal government, that was the beginning of all modern data processing in business.
Why was the Hollerith desk invented?
Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.
What was designed by Herman Hollerith?
Herman Hollerith is widely regarded as the father of modern automatic computation. He chose the punched card as the basis for storing and processing information and he built the first punched-card tabulating and sorting machines as well as the first key punch, and he founded the company that was to become IBM.
Who invented the computer?
Charles BabbageComputer / InventorCharles Babbage, an English polymath, is often thought of as "the man who invented computers". From 1822 until his death in 1871, he designed 3 computers, but never actually constructed any of them, due to lack of funding.
When did Herman Hollerith invented the computer?
Titled "Art of Compiling Statistics", it was filed on September 23, 1884; U.S. Patent 395,782 was granted on January 8, 1889. Hollerith initially did business under his own name, as The Hollerith Electric Tabulating System, specializing in punched card data processing equipment.
How does the Hollerith machine work?
A pantograph used to create punch cards. To begin tabulating data, census information had to be transferred from the census schedules to paper punch cards using gang punches and pantographs. Using this equipment, Census Bureau clerks "punched" each card to represent specific data on the census schedule.

Who was Hollerith's teacher?
Immediately after graduation from the Columbia University School of Mines in 1879, Hollerith became an assistant to his teacher William P. Trowbridge in the U.S. census of 1880.
Who invented the tabulating machine?
Herman Hollerith, (born February 29, 1860, Buffalo, New York, U.S.—died November 17, 1929, Washington, D.C.), American inventor of a tabulating machine that was an important precursor of the electronic computer.
When was the Tabulating Machine Company founded?
In 1896 Hollerith organized the Tabulating Machine Company, incorporated in New York, to manufacture the machines; through subsequent mergers it grew into the International Business Machines Corporation (IBM). This cover of Scientific American, August 30, 1890, displays various aspects of Herman Hollerith's invention.
When did Hollerith start the punch card machine?
His machines were used for the 1890 census and accomplished in one year what would have taken nearly 10 years of hand tabulating. In 1896, Hollerith founded the Tabulating Machine Company to sell his invention, the Company became part of IBM in 1924. Hollerith first got his idea for the punch-card tabulation machine from watching ...
What was Hollerith's punch card?
Hollerith's punch cards and tabulating machines were a step toward automated computation. His device could automatically read information which had been punched onto a card. He got the idea and then saw Jacquard's punchcard. Punch card technology was used in computers up until the late 1970s.
Who invented the punch card?
For his tabulation machine, he used the punch card invented in the early 1800s, by a French silk weaver called Joseph-Marie Jacquard. Jacquard invented a way of automatically controlling the warp and weft threads on a silk loom by recording patterns of holes in a string of cards.
When did punch cards start being used?
Punch card technology was used in computers up until the late 1970s. Computer "punched cards" were read electronically, the cards moved between brass rods, and the holes in the cards created an electric current where the rods would touch.
