A century of Invention – Very first Computer

There’s been cited as calling in the computing world when discussing what was the first computer invented.

For years, the accepted pioneer of your digital age was the ENIAC, short for Electronic Numerical Integrator And Computer, perhaps because the story associated with growth was one worthy for tabloids and tv.

As World War II was creating any close, the Army had run short of mathematicians and were willing to recruit women. Six women were accepted function with on “Project PX” at the University of Pennsylvania’s Moore School of Electrical Engineering, under John Mauchly and T. Presper Eckert. The women’s job were to program firing tables and ballistic trajectories using ENIAC. Their work laid the groundwork for shows. The completed machine was unveiled on Feb. 14, 1946 at the University of Pennsylvania. Within the armed forces had funded the price almost $500,000. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. It is widely considered to function as first computer invented, considering its highly functional status from late 1950s.

However, its “first” status was challenged in court when Rand inventors help Corp. bought the ENIAC patent and started charging royalties. Honeywell Corporation. refused to pay and challenged the patent in 1967. It was learned that Mauchly, amongst the leaders of the Project PX at the University of Pennsylvania, had seen early prototype of a device being built at the Iowa State College called the Atanasoff-Berry Computer.

Professor John Vincent Atanasoff and graduate student Cliff Berry began development on the ABC in 1937 and it remained developed until 1942 at the Iowa State College (now Iowa State University). Eventually, it could solve equations containing 29 variables.

In 1973, Ough.S. Federal Judge Earl R. Larson released his decision how to get a patent on an idea the ENIAC patent a product by Mauchly and Eckert was invalid along with the ABC was the first computer found. However, the ABC was never fully functional, so the favorite opinion to the present day has the ENIAC as the first electronic computing piece of equipment. The Smithsonian Institute’s Museum of American History in Washington displays most of what remains of the ENIAC, alongside parts of the ABC.

However, there’s another twist to this tale. The easiest computer is an electronic device designed to just accept data, perform prescribed mathematical and logical operations and display the results. Germany’s Konrad Zuse created what was fundamentally the first programmable calculator in the mid-1930s in his parent’s living room. Zuse’s Z1 had 64-word memory and a clock speed of 1 Hz. Programming the the Z1 required the user to insert tape to be able to punch tape reader and then receive his results the punch tape dispenser – making it possibly the first computer invented.
