Computer Timeline

500 – The Abacus – A mechanical aid for simple arithmetic was used by the Babylonians.

1300 – The Abacus – The Abacus design we are familiar with in the modern day was developed in China.

1470 – Drawloom – A loom where a draw boy was no longer needed as it returned the ropes towards the weaver in front of the loom. (Created by Jean le Calabrais)

1623 – Calculating Clock – Described in notes as a “counting machine with an automated tens-carry”. (Designed by Wilhelm Schickard)

1642 – Pascaline, also known as Arithmetic Machine or Pascal’s Calculator – Machine designed to add and subtract two numbers and perform multiplication and division through repeated addition or subtraction. (Invented by Blaise Pascal)

1678 – De Gennes’ Loom – The pivoting arm supports the pivot, and the rocking bar of all mechanisms pivots the flexible manipulation device. This helps keep the pivot pressed against the fixed bearing surface on the frame during the braiding process. (Invented by Jean-Baptiste de Gennes)

1694 – Stepped Reckoner – The first calculator that could perform all four basic arithmetic operations. Mechanical problems kept it from working reliably. (Invented by Gottfried Wilhelm Leibniz)

1725 – Bouchon’s Loom – Mechanical loom controlled by perforated paper tape, partially automating the tedious setting up process of the drawloom. (Created by Basile Bouchon)

1728 – Falcon’s Loom – First machine to be controlled by punch cards. The loom used perforated cards tied together in an endless chain. (Invented by Jean-Baptiste Falcon)

1733 – The Flying Shuttle – A shuttle mechanism to increase the rate of weaving. (Patented by John Kay of Bury)

1745 – Automatic Loom – An design for a fully automatic loom. It automated the movement of the shuttle taking the weft thread back and forth across the loom, interweaving with the warp threads. It was powered by a single hand crank and did not use the Flying Shuttle. It was slower than a loom by hand, therefore it was not a success. (Created by Jacques de Vaucanson)

1771 – Cromford Mill – The first successful water powered cotton spinning mill. (Built by Sir Richard Arkwright)

1784 – Power Loom – Inspired by the water-powered spinning mills, it was a mechanized loom that used a large shaft to automate the loom, speeding up textile manufacturing. It allowed sixty picks per minute, when by hand most could do around 20-40 picks per minute. (Invented by Edmund Cartwright)

1804 – Jacquard Machine, also known as a Jacquard Loom – The automatic loom used the Flying shuttle and Falcon’s punch card control mechanism. (Patented by Joseph Marie Jacquard)

(Created by George Scheutz)

1855 – Hughes’ Telegraph – No code telegraph. The operator at the sending station used a keyboard resembling a piano, with each key representing a character of the alphabet. When a key was pressed, the corresponding character was printed on a strip of paper at the receiving end. (Created by David Edward Hughes)

1873 – Remington Typewriter – The first production of a typing machine made to print words and numbers with a type-bar system and keyboard. This was the first use of the “QWERTY” keyboard, designed to prevent the typewriters’ mechanical arms from jamming. It was inspired by the Hughes’ Telegraph seen in London. (Patented by Christopher Latham Sholes, Carlos Glidden, and Samuel Soule)

1886 – Hollerith Tabulator – Electrically-operated components that read holes on paper punch cards to capture and process census data. The 1890 census data was processed in just six weeks compared to the 7 years it took to process the 1880 census data. (Invented by Herman Hollerith)

1887 – Comptometer – The first commercially successful key-driven mechanical calculator. Primarily an adding machine, it could also perform subtractions, multiplication, and division. Its keyboard had eight or more columns of nine keys each. Special comptometers with different key arrays were made for specific tasks, such as calculating currency exchanges, times, and Imperial weights.(Patented by Dorr Felt)

1890 – Odhner Arithmometer – The most successful type of mechanical calculator designed. It replaced the heavy, bulky Leibniz cylinder in the Thomas’ arithmometer with a lighter, smaller pinwheel disk. (Invented by W. T. Odhner)
