“Sts. Cyril and Methodius”

The invention and the dissemination of literacy and books in the then spoken Bulgarian language is one of the most significant facts in the political and cultural history of Bulgaria and Eastern Europe. This event is associated with the names of Constantine Cyril the Philosopher and his brother Methodius who invented the earliest Bulgarian alphabet and translated the principal books of the Christian doctrine into the Christian ideological and theoretical heritage.

John Atanasoff (1903 - 1995)

John Atanasoff was born on 4 October 1903 a few miles west of Hamilton, New York. His father was a Bulgarian immigrant named Ivan Atanasov. His last name was changed to Atanasoff by immigration officials at Ellis Island when he arrived with an uncle in 1889, and later on, his first name was changed to John.
In late 1939, John Atanasoff teamed up with Clifford Berry to build a prototype. They created the first computing machine to use electricity, vacuum tubes, binary numbers and capacitors. The capacitors were in a rotating drum that held the electrical charge for the memory. The brilliant and inventive Berry, with his background in electronics and mechanical construction skills, was the ideal partner for Atanasoff. The prototype won the team a grant of $850 to build a full-scale model. They spent the next two years further improving the Atanasoff-Berry Computer.

It was there that he invented his process for the production of pure alumina from bauxite. In 1894, he returned to Austria but died suddenly at the age of 57. Details about Bayer and his time will be outlined.
