Simula, invented in the late 1960s by Nygaard and Dahl as a superset of Algol 60, was the first language designed to support object-oriented programming. It was designed to track a target, and aim & fire a torpedo from a submarine. It had a 23cm (9”) CRT monitor and came with a keyboard and mouse. Although he might not be the man who invented computers, Turin is certainly the man who invented computer science! "Booting Up a Computer Pioneer's 200-Year-Old Design." Charles Babbage, an English polymath, is often thought of as “the man who invented computers”. Generally, these fulfilled a single purpose. (Image credit: IBM) 1981 : The first IBM personal computer, code-named "Acorn," is introduced. Alan Turing invented computer science. The ENIAC contained 20,000 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and 5,000,000 hand-soldered joints. Kim, Eugene Eric and Betty Alexandra Toole. The EDVAC was built from 6,000 vacuum tubes, 12,000 diodes, consumed around ⅓ of the power of its predecessor and weighed a mere 7,800kg (8.7 short tons). It could execute up to 5,000 additions per second, several orders of magnitude faster than its electromechanical predecessors. Park, Edwards. In fact, you’re using one right now! The first computer, the Antikythera mechanism (200 BC – 70 BC) was mechanical. The disadvantage was that it took days to rewire the machine for each new problem. May 1999. This gave ENIAC a lot of flexibility and meant that, while it was built for a specific purpose, it could be used for a wider range of problems. Over a 10 year period, he received a staggering £17,000 (over £2,000,000 in 2020) from the British government, unfortunately, they eventually lost faith in his idea and cut the funding. You might be surprised to learn that many computer pioneers struggled to get funding for their ideas and faced skepticism from their contemporaries. The IBM 5100 had a 16-bit processor, took quarter-inch cartridge (QIC) magnetic tape drives and gave users the option to switch the screen between white on black and black on white. The MITS Altair 8800 (1974) was the first PC that was any kind of commercial success. The computer sold for $2,795 (around $7,234 in 2020). The first computer, the Antikythera mechanism (200 BC – 70 BC) was mechanical. It lacked many of the functionalities of modern computers; it was designed for one specialist task and was not Turing complete. Touching the screen would break the infrared and place the cursor at the desired location. By the time it was decommissioned, in 1955, it had been used to solve problems as diverse as wind tunnels, random number generators, and weather prediction. In the United States, government funding went to a project led by John Mauchly, J. Presper Eckert, Jr., and their colleagues at the Moore School of Electrical Engineering at the University of Pennsylvania; their objective was an all-electronic computer. National Library of Wales/Wikimedia Commons, "Analytical Engine." ENIAC, the first programmable general-purpose electronic digital computer, built during World War II by the United States and completed in 1946. Under contract to the army…. Smithsonian Magazine. Computers, love them or hate them, we rely on them every day. The ENIAC (1945) was the first electronic general-purpose digital computer, it filled a room. ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States. It was not, a commercial success. The project was led by John Mauchly, J. Presper Eckert, Jr., and their colleagues. 2, a second “computer”. His work did not stop at the end of WW2!

In 1938 the United States Navy invented the Torpedo Data Computer (TDC), possibly the world’s first electromechanical computer. The computer was so successful that the company had to hire extra staff just to keep up with demand! (With 1,500 mechanical relays, ENIAC was still transitional to later, fully electronic computers.).
