Professor John Atanasoff and graduate student Clifford Berry built the world's first electronic-digital computer at Iowa State University between 1939 and 1942. The Atanasoff-Berry Computer represented several innovations in computing, including a binary system of arithmetic, parallel processing, regenerative memory, and a separation of memory and computing functions.

During a similar time period Alan Turing of Cambridge University , Max Newman and Mr Tommy Flowers of British GPO need a mention. Alan Turing developed the thery for the code breaking and Mr Newman & Tommy Flowers made a practical design. It was no mean technical feat to keep thousands of tubes working long enough to do useful work. They developed a several working large dedicated Tube (valve) computers for breaking the code from the Enigma machine used by Germany in WWII. Both worked at the Bletchley Park Code breaking centre As they worked for the UK Government and thus covered by the "Official Secrets Act" much of their work and achievements were kept secret for many years. They have recently rebuilt one of the Computers for the Museum.

In more recent times, Alice Burks, wife of an early computer engineer Arthur Burks, claims to have established paternity by analyzing documents and reviewing oral testimony for her 2003 book entitled 'Who Invented The Computer?: The Legal Battle That Changed Computer History'. She concluded that the father of the electronic computer is John Vincent Atanasoff - not J. Prespert Eckert and John W. Mauchly, who are named as inventors of Patent No. 3,120,606 for 'Electronic Numerical Integrator and Computer' (ENIAC) that issued in 1964 based on a 1947 filing date.

How could Charles Baggage invent the electronic computer if he was born in 1791 and it was invented in 1641?

The electronic computer was not invented in 1641, there was no electronics in 1641. The electronic computer was invented in the 1940s. Charles Babbage did invent the programmable digital computer, the Analytical Engine, but it was mechanical not electronic.

When did the computer begin?

The world's first electronic computer was the Colossus computer, invented by Tommy Flowers during WW2. The earliest computer (it was mechanical) was invented by Charles Babbage in the 1800s.

What is considered the first successful high-speed electronic digital computer?

The first successful high-speed electronic digital computer was the Colossus computer, invented by Tommy Flowers during WW2. The earliest computer (it was mechanical) was Charles Babbage's Analytical Engine, invented in 1834.
