The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] The device was limited by the technology of the day. The ABC's priority is debated among historians of computer technology, because it was neither programmable , nor Turing-complete . [ 2 ]
Clifford Berry was born April 19, 1918, in Gladbrook, Iowa, to Fred and Grace Berry. [1] His father owned an appliance repair shop, where he was able to learn about radios. [ 1 ] He graduated from Marengo High School in Marengo , Iowa, in 1934 as the class valedictorian at age 16. [ 2 ]
In December 1939 John Atanasoff and Clifford Berry completed their experimental model to prove the concept of the Atanasoff–Berry computer (ABC) which began development in 1937. [40] This experimental model is binary, executed addition and subtraction in octal binary code and is the first binary digital electronic computing device.
With a grant of $650 received in September 1939 and the assistance of his graduate student Clifford Berry, the Atanasoff–Berry Computer (ABC) was prototyped by November of that year. According to Atanasoff, several operative principles of the ABC were conceived by him during the winter of 1938 after a drive to Rock Island, Illinois.
Together, they created the Atanasoff-Berry computer, also known as the ABC which took five years to complete. [8] While the original ABC was dismantled and discarded in the 1940s, a tribute was made to the late inventors; a replica of the ABC was made in 1997, where it took a team of researchers and engineers four years and $350,000 to build.

Omar Cruz, who is the first in his family to graduate high school, took college courses at Central Piedmont Community College during his senior year to jumpstart his career as a automotive technician.
The later Atanasoff–Berry Computer ("ABC"), designed by John Vincent Atanasoff and Clifford Berry, was the first fully electronic digital computing device; [80] while not programmable, it pioneered important elements of modern computing, including binary arithmetic and electronic switching elements, [81] [82] though its special-purpose nature ...
