Computing History 1

Invented a machine that used punched cards for data input assisted with the 1890 census Herman Hollerith
This word was originally a job title computer
Wrote the first computer program Ada Byron
Early Device to assist with mathematical calculations that consisted of beads and string abacus
Numbers carved on sticks which when crossed could actually multiply Napier's Bones
Drew plans for a sophisticated calculating machine called the difference engine, which wasn’t actually built because of the lack of technology to make the parts. Charles Babbage
Four-function calculator built by Leibniz. (It could add, subtract, multiply, and divide.) Stepped Reckoner
Built a loom that used punched cards to make patterns in fabric. Jacquard
First built in England in 1632 and still in use in the 1960's by the NASA engineers of the Mercury, Gemini, and Apollo programs which landed men on the moon slide rule
Gear-driven one-function calculator (it could only add). Has a computer language named after him. Pascaline
Built a company, the Tabulating Machine Company which, after a few buyouts eventually became International Bussiness Machines, known today as IBM. IBM grew rapidly and punched cards became ubiquitous. Hollerith's
Charles Bobbage was proposing a steam driven caculating machine in size of a room which was called Difference Engine
Consisted of a card reader which sensed the holes in the cards, a gear driven mechanism which could count and a large wall of a dial indicators to display the results of the counts.. Hollerith Desk
Earned her spot in history as the first computer programmer.. Ada Byron
Gottfried Wihelm Leibniz (co-inventor with Newtonof calculus) manage to build a four-function (addition, subtraction,multiplication, and division) calculator that he called The Stepped Reckoner
His device, large as a house and powered by 6 stem engines, would be more general purpose in nature because it would be programmable, thanks to the punched card technology Jacquard Babbage
Invented a power loom that could base its weave (and hence the design on fabric) upon a pattern automatically read from punched wooden careds, held together in row by rope. Jacquard
Invented the Pascaline as an aid for his father who was a tax collector Blaise Pascal
