2. The Atanasoff-Berry Computer was the world's first electronic digital computer. It was built by John Vincent Atanasoff and Clifford Berry at Iowa State University during 1937-42. This prototype of the first computer included four significant and entirely novel operating principles in its operation - the binary system, regenerative data storage, logic circuits as elements of a program, and electronic elements as data carrying media. "After the prototype had started working, we were convinced we could build a computer capable of calculating whatever we would like to", wrote Atanasoff.

3. Comparatively few people know that the genius who invented the first computer and initiated the computer revolution, was of Bulgarian ancestry. John Atanasoff was a prominent American inventor who took pride in his Bulgarian heritage and maintained strong ties to his ancestral home of Bulgaria. JOHN VINCENT ATANASOFF was born on 4 October 1903, a few miles west of Hamilton, New York. His father was a Bulgarian immigrant named Ivan Atanasov. John Atanasoff at the time when he works on ABC- Computer,1938 Physics Building at Iowa State University In the basement of this building is where the computer was first created in 1939.

4. The principles of John Atanasoff's computer, though seemingly outdated today, are the basis of the thousands of millions of computers, without which modern society cannot exist. Every Bulgarian knows and prides in the holy brothers, St. Cyrill and St. Methodius, who created the alphabet of all Slavonic peoples. Similarly, John Atanasoff, a man of Bulgarian extraction, opened the road to the world information society.
