Computer Science and Technology[edit]

Prof. John Atanasoff, the inventor of the computer.


Prof. Georgi Nadjakov discovered the photoelectrets.
Prof. Ivan Stranski, the father of the kinetic theory of crystal growth (1940)




Prof. Carl Djerassi, the inventor of the oral contraceptive pill.



Assen Jordanoff, inventor, engineer, and aviator-pioneer.
  • Assen Jordanoff - Jordaphone - the predecessor of the modern answering machine and tape recorder. Frozen Gasoline System for airplanes. Reverse Thrust device for jet engines.
  • Simeon Petrov - Captain Simeon Petrov, Bulgarian Air Force, invented the world's first purpose-built air-to-surface bomb in 1912. The innovations included aerodynamically stabilized x-tail and an impact detonator. The majority of aircraft bombs to date follow Petrov's design. The Bulgarian Air Force deployed the original prototype, thus becoming the first military force in the world to conduct tactical airplane bombing in a full-scale war in 1912.
  • Christo Toprakchiev, a Bulgarian Air Force pilot in 1912, during the First Balkan War first proposed the use of aircraft to drop "bombs" (called grenades in the Bulgarian army at this time) and performed the mission on Turkish positions.[15]



Elias Canetti, Nobel laureate in Literature (1981).
  • Elias Canetti - Nobel laureate in Literature 1981 "for writings marked by a broad outlook, a wealth of ideas and artistic power"[17]


  • Early Renaissance - The world famous frescos in the Boyana Church from 1239 AD have been described by Andre Grabar and many scholars, as Early Renaissance or precursors of Renaissance Art well before this period started in Italy. The murals are work of the unknown Boyana Master and his disciples who are believed to have been representatives of the Tarnovo Art School in the Second Bulgarian Empire (1185-1396 AD). The frescos have been compared to the work of Giotto who is generally considered the first in a line of great artists who contributed to the Italian Renaissance. The Boyana Church has been declared by UNESCO a World Heritage site. UNESCOArcheology in Bulgaria
