Computer Awareness Notes :A Complete History of Computers: From the 1800s to Now

Computers in the 1800s

1801: In France, weaver and merchant Joseph Marie Jacquard creates a loom that uses wooden punch cards to automate the design of woven fabrics. Early computers would use similar punch cards.

1822: Thanks to funding from the English government, mathematician Charles Babbage invents a steam-driven calculating machine that was able to compute tables of numbers.

1890: Inventor Herman Hollerith designs the punch card system to calculate the 1880 U.S. census. It took him three years to create, and it saved the government $5 million. He would eventually go on to establish a company that would become IBM.

Computers from the 1900-1950s

1936: Alan Turing developed an idea for a universal machine, which he would call the Turing machine, that would be able to compute anything that is computable. The concept of modern computers was based on his idea.

1937: A professor of physics and mathematics at Iowa State University, J.V. Atanasoff, attempts to build the first computer without cams, belts, gears, or shafts.

1939: Bill Hewlett and David Packard found Hewlett-Packard in a garage in Palo Alto, California. Their first project, the HP 200A Audio Oscillator, would rapidly become a popular piece of test equipment for engineers.

In fact, Walt Disney Pictures would order eight to test recording equipment and speaker systems for 12 specially equipped theaters that showed Fantasia in 1940.

Also in 1939, Bell Telephone Laboratories completes The Complex Number Calculator, designed by George Stibitz.

1941: Professor of physics and mathematics at Iowa State University J.V. Atanasoff and graduate student Clifford Berry design a computer that can solve 29 equations simultaneously. This is the first time a computer is able to house data within its own memory.

That same year, German engineer Konrad Zuse creates the Z3 computer, which used 2,300 relays, performed floating-point binary arithmetic, and had a 22-bit word length. This computer was eventually destroyed in a bombing raid in Berlin in 1943.

Additionally in 1941, Alan Turing and Harold Keen built the British Bombe, which decrypted Nazi ENIGMA-based military communications during World War II.

1943: John Mauchly and J. Presper Eckert, professors at the University of Pennsylvania, build an Electronic Numerical Integrator and Calculator (ENIAC). This is considered to be the grandfather of digital computers, as it is made up of 18,000 vacuum tubes and fills up a 20-foot by 40-foot room.

Also in 1943, the U.S. Army asked that Bell Laboratories design a machine to assist in the testing of their M-9 director, which was a type of computer that aims large guns to their targets. George Stibitz recommended a delay-based calculator for the project. This resulted in the Relay Interpolator, which was later known as the Bell Labs Model II.

1944: British engineer Tommy Flowers designed the Colossus, which was created to break the complex code used by the Nazis in World War II. A total of ten were delivered, each using roughly 2,500 vacuum tubes. These machines would reduce the time it took to break their code from weeks to hours, leading historians to believe they greatly shortened the war by being able to understand the intentions and beliefs of the Nazis.

That same year, Harvard physics professor Howard Aiken built and designed The Harvard Mark 1, a room-sized, relay-based calculator.

1945: Mathematician John von Neumann writes The First Draft of a Report on the EDVAC. This paper broke down the architecture of a stored-program computer.

1946: Mauchly and Eckert left the University of Pennsylvania and obtained funding from the Census Bureau to build the UNIVAC. This would become the first commercial computer for business and government use.

That same year, Will F. Jenkins published the science fiction short story A Logic Named Joe, which detailed a world where computers, called Logics, interconnect into a worldwide network. When a Logic malfunctions, it gives out secret information about forbidden topics.

1947: Walter Brattain, William Shockley, and John Bradeen of Bell Laboratories invented the transistor, which allowed them to discover a way to make an electric switch using solid materials, not vacuums.

1948: Frederick Williams, Geoff Toothill, and Tom Kilburn, researchers at the University of Manchester, develop the Small-Scale Experimental Machine. This was built to test new memory technology, which became the first high-speed electronic random access memory for computers. The became the first program to run on a digital, electronic, stored-program computer.

1950: Built in Washington, DC, the Standards Eastern Automatic Computer (SEAC) was created, becoming the first stored program computer completed in the United States. It was a test-bed for evaluating components and systems, in addition to setting computer standards.

1953: Computer scientist Grace Hopper develops the first computer language, which is eventually known as COBOL, that allowed a computer user to use English-like words instead of numbers to give the computer instructions. In 1997, a study showed that over 200 billion lines of COBOL code were still in existence.

That same year, business man Thomas Johnson Watson Jr. creates the IBM 701 EDPM, which is used to help the United Nations keep tabs on Korea during the war.

1954: The FORTRAN programming language is developed by John Backus and a team of programmers at IBM.

Additionally, IBM creates the 650, which was the first mass-produced computer, selling 450 in just one year.

1958: Jack Kirby and Robert Noyce invented the integrated circuit, which is what we now call the computer chip. Kilby was awarded the Nobel Prize in Physics in 2000 for his work.

From the 1960-1970s

1962: IBM announces the 1311 Disk Storage Drive, the first disk drive made with a removable disk pack. Each pack weighed 10 pounds, held six disks, and had a capacity of 2 million characters.

Also in 1962, the Atlas computer makes its debut, thanks to Manchester University, Ferranti Computers, and Plessy. At the time, it was the fastest computer in the world and introduced the idea of “virtual memory”.

1964: Douglas Engelbart introduces a prototype for the modern computer that includes a mouse and a graphical user interface (GUI). This begins the evolution from computers being exclusively for scientists and mathematicians to being accessible to the general public.

Additionally, IBM introduced SABRE, their reservation system with American Airlines. It program officially launched four years later, and now the company owns Travelocity. It used telephone lines to link 2,000 terminals in 65 cities, delivering data on any flight in under three seconds.

1968: Stanley Kubrick’s 2001: A Space Odyssey hits theaters. This cult-classic tells the story of the HAL 9000 computer, as it malfunctions during a spaceship’s trip to Jupiter to investigate a mysterious signal. The HAL 9000, which controlled all the ship, went rogue, killed the crew, and had to be shut down by the only surviving crew member. The film depicted computer demonstrated voice and visual recognition, human-computer interaction, speed synthesis, and other advanced technologies.

1969: Developers at Bell Labs unveil UNIX, an operating system written in C programming language that addressed compatibility issues within programs.

1970: Intel introduces the world to the Intel 1103, the first Dynamic Access Memory (DRAM) chip.

1971: Alan Shugart and a team of IBM engineers invented the floppy disk, allowing data to be shared among computers.

That same year, Xerox introduced the world to the first laser printer, which not only generated billions of dollars but also launched a new era in computer printing.

Also, email begins to grow in popularity as it expands to computer networks.

1973: Robert Metcalfe, research employee at Xerox, develops Ethernet, connecting multiple computers and hardware.

1974: Personal computers are officially on the market! The first of the bunch were Scelbi & Mark-8 Altair, IBM 5100, and Radio Shack’s TRS-80.

1975: In January, the Popular Electronics magazine featured the Altair 8800 as the world’s first minicomputer kit. Paul Allen and Bill Gates offer to write software for the Altair, using the BASIC language. You could say writing software was successful, because in the same year they created their own software company, Microsoft.

1976: Steve Jobs and Steve Wozniak start Apple Computers and introduce the world to the Apple I, the first computer with a single-circuit board.

Also in 1976, Queen Elizabeth II sends out her first email from the Royal Signals and Radar Establishment to demonstrate networking technology.

1977: Jobs and Wozniak unveil the Apple II at the first West Coast Computer Faire. It boasts color graphics and an audio cassette drive for storage. Millions were sold between 1977 and 1993, making it one of the longest-lived lines of personal computers.

1978: The first computers were installed in the White House during the Carter administration. The White House staff was given terminals to access the shared Hewlett-Packard HP3000.

Also, the first computerized spreadsheet program, VisiCalc, is introduced.

Additionally, the LaserDisc is introduced by MCA and Phillips. The first to be sold in North America was the movie Jaws.

1979: MicroPro International unveils WordStar, a word processing program.
