First inventor is an expert mathematician Charles Babbage in 1822, but the subsequent development can not be separated from the service of the inventors of the next generation. Charles Babbage in 1822, with a brilliant idea created a tool that can assist humans in performing complex calculations. The engine is not completed at this time is in the London Museum of Science. From this discovery begins computers.
In 1937 Dr. John V Atanasoff and Clifford Berry designed the first electronic digital computer. With the name of the ABC (Atanasoff-Berry Computer). ABC can only count the plus and minus.
In 1943 During World War 2, the British scientist named Alan Turing electronic computers specifically designed for the British Army. Code used to penetrate the German defenses.
In 1944 Howard Hathaway Aiken (American) make the Mark I. A computer that created the first digital count. Has 7.45 feet wide x 50 feet, with a weight of 35 tons. Mark I can be used to calculate probabilities.
In 1945 Dr. John von Neumann writes data storage concept. It was still in the form of ideas.
In 1946 Dr. John W. Mauchly and J. Presper Eckert, jr. completing the first large-scale computer, called ENIAC (Electronic Numerical Integrator And Computer). The world knows these two men as Inventors COMPUTER.
ENIAC weighed 30 tons, comprising 18,000 tube lights (transistor size), has an area of 30 feet x 50 feet, using the power of 160,000 watts. The first time the computer is turned on, the entire electrical system in Philadelphia sudden death.
ENIAC can calculate not only added to the lack of time, but also can be programmed to perform a simple process. Than the Mark I, which is only able to calculate, it can be seen that the ENIAC was the first in the world COMPUTER.
In 1947 The first transistor was invented by William Shockley, John Bardeen, and Walter Brattain. Since the transistor was invented, computers are getting smaller size ..
From the history above, it can be seen that the inventor COMPUTER (not a calculator) is Dr. John W. Mauchly and J. Presper Eckert, jr ..
So the answer is First Computer Inventor: Dr. John W. Mauchly and J. Presper Eckert, jr
