Who invented Computer?

Charles Babbage, of London, spent from 1823 to 1871 working on his ‘analytical machine’, designed to take instructions from punched cards, calculate with the aid of a memory bank, and print out a solution.
Unfortunately, despite all his efforts, the very precise engineering work needed to make the machine a complete success was impossible at the time.
Herman Hollerith, of New york. USA, who worked for the US Census Bureau, devised a machine in 1889 which used punched cards to store the information needed for the census, and so halved the time it took to work things out. He left the Census Bureau in 1896 to form the Tabulated Machine Company to manufacture the equipment which he had invented – and that later became part of IBM(International Business Machine).
The first electronic computer was the Electronic Numerical Integrator and Computer (known as ‘ENIAC’), Developed for the US Army ordnance in 1946.
Unfortunately, it weighed 30 tons and used 18,000 radio valves! Further, the machine got so hot while it was working that it could be sued only for short period of time.
Only after the transistor had been invented was the modern electronic computer possible, and the first to be produced was by Remington Rand in America and Ferranti in Britain, simultaneously in 1951.

Did anyone remember Karl Zuse, a german engineer, who built the first working "computer" (electronic one based on realy-working circuits) Z3 in 1940?

flowers was an english man who invented and built an electronic computer during the ww2 it was ordered to be destroyed by churchil after the war,
ironic that it was also used by the american forces in the war and emediatly after the war they built one the same

I think you have to remember JOHN FON NEUMANN. He is very important person.

i thought it is phnomenen
i studied it i think he is the one

Britain developed the first working computer called COLLOSSUS.
It was built in Bletchley Park and was designed to decode German inigma machine generated coded messages for their military.
This was in 1940 long before the ENIAC (1946)
