This is not a question with a simple answer. It partly depends onwhat you mean by "computer". Many inventors contributed to thehistory of computers and that a computer is a co…mplex piece ofmachinery made up of many parts, each of which can be considered aseparate invention. Many say the first computer is the "differenceengine." The first of these devices was conceived in 1786 by J.H.MÃ¼ller. It was never built. Difference engines were forgotten and then rediscovered in 1822 byEnglishman Charles Babbage, who is known as "the father of theComputer". This machine used the decimal numbers system and waspowered by cranking a handle. The British government first financedthe project but then later cut off support. Babbage went on todesign his much more general analytical engine but later returnedand produced an improved design (his "Difference Engine No. 2")between 1834 and 1869. But he was never able to build any of thesedesigns. Others point out that this is the first DIGITAL computer. Theearliest computer known is the Antikythera Machine, a mechanicalanalog device that computed the positions of the astrological signson any given date, past or future. It was discovered in an ancientshipwreck in the Mediterranean Sea and dates to approximately 250BC. The designer/builder is not known, but because of itssimilarity to other mechanical devices known to have been designedby Archimedes, it is probably his work. Still others will say the abacus is the first computer. They wereinvented by the Chinese between 2600 BC and 300 BC is considered asthe first computer ever. Abacus was used by the merchants andClerks in China. However the abacus is NOT automatic, but it isdigital; so it is more of a "calculation aid" or "calculator" thana computer. Here is still more input: . If you mean Electronic Computer, it was a man called AlanTuring from Cambridge UK, who was drafted in to Bletchley parksecret base where they worked at cracking the WWII enigma codesthat the Germans used every day. The Germans changed their Enigmamachines to a four digit code maker. However, Because what went onat Bletchley Park the computer made from thousands of valves waskept top secret up until recently. The computer, named Colossus wassmashed to pieces at the end of the war. The buildings have nowbeen restored as a tourist center. . The Colossus Mark I 1943, the world's first programmable,digital, electronic, computing devices... its follow up the Mark IIwas used by British codebreakers to read encrypted German "tunny"teletype cypher during World War II (notably D Day) . The first computer, or "modern computer" was invented in WorldWar II by a German engineer, Konrad Zuse in 1941 called the Z3. TheZ3 was a fully digital, binary, floating point arithmetic,electromechanical relay machine programmed with punch recycled 35mmfilm. About the only things it lacked were conditional branches,loops, and subroutines. It was destroyed in an allied bombing raidafter completion but before it saw real use. . It was Konrad Zuse. He invented the z1, z2, z3, z4 and otherones. The z3 was the first fully functional program-controlledelectromechanical digital computer in the world-completed in 1941.Charles Babbage just made a mechanical computing machine. . The first electronic digital computer was invented by BulgarianJohn Vincent Atanasoff. He named it the Atanasoff Berry Computer,or the ABC. It was the world's first electronic digital computerand built between 1937-42 by John Vincent Atanasoff and CliffordBerry at Iowa State University. It used regenerative memory (i.e.dynamic), parallel processing, binary arithmetic and splitcomputing functions (routines) away from memory use and management.However it was not programmable (it could only solve simultaneousequations problems). . Now, if we're talking technical knowledge and actual precursorsto the PC - IBM may have accidentally spread it around when theyallowed cloning of the PC architecture. But they were not thefirst. [This answer refers to desktop "personal" computers. Thesewere far from the first computers. . These are all pre-IBM machines: MITS ALTAIR 8800, Apple II,TRS80, Atari 800 and the Commodore 64. [This answer refers todesktop "personal" computers. These were far from the firstcomputers. . Purists who claim that the ALTAIR was not the first, will sayit was 'Simon' by Berkley Enterprises, 1950, costing $300. [Thisanswer refers to desktop "personal" computers. These were far from the first computers.] . The first completely electronic computer was developed inEngland in 1943. It was known as Colossus. It took up 1,000 Sq. ft.weighed 30 tons/60,000 pounds. And took 150 kilowatts which isenough power to light up a small town. . The first working computer (in the modern sense) was inventedby Konrad Zuse. But others had created machines or ideas close toit before. These were people like Pascal, Leibniz and Turing. . The first patent for a working computer (outside the military)was the UNIVAC, created by Drs. John Mauchly and Presper Eckert in1948. They formed the Eckert-Mauchly Computer Corporation, whichwas bought in 1950 (just as they were on the verge of bankruptcy)by Remington Rand. Their computer was used in the 1950 census(starting in mid-1951 when the first one was finished) and byWalter Cronkite in the 1952 Presidential election. . The ENIAC patent was declared invalid on October 19, 1973, byUS Federal Judge Earl R. Larson. He attributed Atanasoff and Berrywith the invention of the electronic digital computer. For moreinformation see the related Link. . If you define a computer as the first device for doingmathematical calculations, the answer would be the "BabbageDifference Engine", invented by Charles Babbage but nevercompletely built. However, computers trace their lineage to19th-century power looms which became "programmable" by use ofsomething akin to a punch-card which was used to determine whichcolor thread would be used at any given time in the loom's weavingprocess. On an even more basic level, you could consider the firstuse of cams to determine timing of any mechanism (such as steamengine poppet valves) to be the first "computer". Charles Babbage, an English mathematician, originated theconcept of a programmable computer. Considered a "father of thecomputer", Babbage is credited with inventing the first mechanicalcomputer that eventually led to more complex designs. His proposedmodels were the Difference Engine and the Analytical Engine. TheDifference Engine came first around 1822 and was more limited andnot programmable. it was intended to generate mathematical tables.This machine contained 25,000 parts and weighed 15 tons. Babbagefollowed this with a "difference engine 2" which, although wellfunded, was never completed. Babbage also designed a printer to goalong with the computer, but this also was never completed. In1989-1991, the London science museum made a difference engine 2 andprinter from Babbage's design. Both worked perfectly. Theprogrammer for the Analytical Engine, built around 1825, was AdaLovelace (first programmer). None of these machines was ever builtduring Babbage's time, for many reasons including: Babbage couldnever finalize a design he always had to go on to improved designs,arguments with his machinist, funding, etc. American physicist John Atanasoff built the first rudimentaryelectronic computer in the late 1930s and early 1940s, although forseveral decades afterward credit for the first electronic computerwent to the scientists who assembled the Electronic NumericalIntegrator and Computer (ENIAC) for the United States military by1945. Danish physicist Allan Mackintosh recounts in a ScientificAmerican article how Atanasoff first conceived of the designprinciples that are still used in present-day computers. Dr.Atanasoff's Computer The men who for decades were credited withinventing the first electronic digital computers were not, in fact,first. That honor belongs to a once forgotten physicist named JohnV. Atanasoff.
Charles Babbage. His computer was intended to produce logarithmtalbes used in navigation.
Several people had attempts at inventing the computer. Charles Babbage, in Victorian times, made a mechanical machine that was programmable and could solve equations. The …first electronic computer was invented by several people, at Bletchly park during the second world war, to solve German code messages. This was top secret, so was not acknowledged as the first, until recently. The need for a computer arose in making tables, like log tables, that needed repetitive calculations. Early computers were used for calculating trajectory of missiles such as shells. Programing arose in the making of looms that could produce decrotive cloth, quickly, cheaply and easily. The modern computer could only be realised with the development of transistors and integrated circuits. Then all the previous developments could be brought together, in a machine that took up less room than a whole building and consume less electricity, than the entire national grid. Hats off for Shockley and Bardeen at Bell laboratories, for the transistor.
It is not a simple answer. The real answer is that many inventors helped the history of the computer. It is made up of many parts, each part is considered a separate invention…

As a replacement for human computers.
The first computer was invented by Charles Babbage in London wherehe lived. It was invented between the years of 1833 and 1871.
We could argue that the first computer was the abacus or its descendant, the slide rule, invented by William Oughtred in 1622. But the first computer resembling today's modern… machines was the Analytical Engine, a device conceived and designed by British mathematician Charles Babbage between 1833 and 1871. Before Babbage came along, a "computer" was a person, someone who literally sat around all day, adding and subtracting numbers and entering the results into tables. The tables then appeared in books, so other people could use them to complete tasks, such as launching artillery shells accurately or calculating taxes.

Absolutely. Computer aided manufacture produces accurate results over and over - whereas manually manufactured products are prone to human error.
