History of Computers

By Deera Wijesundarra

1801

Joseph Marie Jacquard, a French merchant and inventor invents a loom that uses punched wooden cards to automatically weave fabric designs.

subsequently early computers would use similar punch cards to manually input instructions

1821

English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers.

Which will give birth to a project funded by the British government, called the "Difference Engine"

Which unfortunately would fail due to a lack of technology at the time

1848

Ada Lovelace, an English mathematician and the daughter of poet Lord Byron, writes the world's first computer program.

while translating a paper on Babbage's Analytical Engine from French into English.

Because of her comments/annotations her transcription will turn out to be three times longer than the original

Siffert wrote in an article for The Max Planck Societ.
"Lovelace also adds a step-by-step description for computation of Bernoulli numbers with Babbage's machine — basically an algorithm — which, in effect, makes her the world's first computer programmer."

1853

Swedish inventor Per Georg Scheutz and his son Edvard design the world's first printing calculator.

The machine is significant for being the first to "compute tabular differences and print the results,"

This would later be popularised by Uta C. Merzbach's book, "Georg Scheutz and the First Printing Calculator" (Smithsonian Institution Press, 1977).

1890

Herman Hollerith designs a punch-card system to help calculate the 1890 U.S. Census.

The machine, saves the government several years of calculations, and the U.S. taxpayer approximately $5 million

Hollerith later establishes a company that will eventually become International Business Machines Corporation (IBM).

the first large-scale automatic general-purpose mechanical analog computer,

1936

Alan Turing, a British scientist and mathematician, presents the principle of a universal machine, later called the Turing machine, in a paper called "On Computable Numbers…"

Turing machines are theoretically capable of computing anything that is computable. The central concept of the modern computer is based on his ideas.

Turing is later involved in the development of the Turing-Welchman Bombe, an electro-mechanical device designed to decipher Nazi codes during World War II.

1941

German inventor and engineer Konrad Zuse completes his Z3 machine, the world's earliest digital computer

Which was Unfortunately estroyed during a bombing raid on Berlin during World War II

"EDSAC ran its first program in May 1949 when it calculated a table of squares and a list of prime numbers,"

1949

scientists with the Council of Scientific and Industrial Research (CSIR), now called CSIRO, build Australia's first digital computer

Council for Scientific and Industrial Research Automatic Computer (CSIRAC) was the first digital computer in the world to play music,

1953

Kilby is later awarded the Nobel Prize in Physics for his work.

1968

Douglas Engelbart reveals a prototype of the modern computer at the Fall Joint Computer Conference, San Francisco.

His presentation, called "A Research Center for Augmenting Human Intellect" includes a live demonstration of his computer, including a mouse and a graphical user interface (GUI)

This marks the development of the computer from a specialized machine for academics to a technology that is more accessible to the general public.

1969

Ken Thompson, Dennis Ritchie and a group of other developers at Bell Labs produce UNIX, an operating system

Which made "large-scale networking of diverse computing systems — and the internet — practical," according to Bell Labs

he team behind UNIX continued to develop the operating system using the C programming language, which they also optimized.

And this richness provides a vast design space for exploring novel and multi-value ways to encode and process data beyond the 0s and 1s of current logic-based, digital architectures.
