Technology and Aviation[]

Assen Jordanoff, inventor, engineer, and aviator-pioneer.

• The first technologically processed gold, and oldest gold treasure and gold jewelry in the world, dating from 4,600 BC to 4,200 BC, was discovered at Varna Necropolis.^[6]
• The first Ferris wheels, the "Pleasure wheels", whose passengers rode in chairs suspended from large wooden rings turned by strong men, may have originated in 17th-century Bulgaria.^[7][8]
• 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.
• Assen Jordanoff (September 2, 1896 - October 19, 1967) was a Bulgarian American inventor, engineer, and aviator. Jordanoff is considered to be the founder of aeronautical engineering in Bulgaria, as well as a contributor to the development of aviation in the United States. Inventor of:
  • the Airbag for aircraft pilots that is nowadays used in automobiles;
  • the Jordaphone - the predecessor of the modern Answering machine and Tape recorder;
  • the Frozen Gasoline System for airplanes;
  • the Reverse thrust device for jet engines.
• John Vincent Atanasoff (October 4, 1903 – June 15, 1995) was an American physicist and inventor of Bulgarian origin, best known for being credited with inventing the first electronic digital computer.^[9]
• Peter Petroff (21 October 1919 – 27 February 2003^[10]) was a Bulgarian American inventor, engineer, NASA scientist, and adventurer. He was involved in the NASA space program. Among his many accomplishments, Petroff assisted in development of one of the earliest computerized pollution monitoring system and telemetry devices for early weather and communications satellites. Petroff helped develop components of one of the world's first digital watches^[10] and an early wireless heart monitor, and many other important devices and methods.
• Ivan (John) Notchev - Bulgarian American aviation engineer and invertor of the jet engines of the Eagle lunar module. They provide the smooth landing of the module module with the cosmonauts, and then their successful return and docking with the spacecraft waiting for them in orbit.
• Angel Balevski (4 March 1910 – 15 September 1997) - famous Bulgarian inventor and engineer who developed, together with Ivan Dimov, a counter-pressure casting method which was a novelty in world foundry technology and was protected by over 100 patent documents in Bulgaria and abroad.
• Roumen Antonov - invented a revolutionary continuously variable transmission,^[11][12] which was never produced.^[13]

Science[]

Prof. Georgi Nadjakov discovered the photoelectrets.

Prof. Ivan Stranski, the father of the kinetic theory of crystal growth (1940)

• Georgi Nadjakov - discovered the essential to modern photocopying.
• Ivan Stranski - Prof. Stranski is considered the father of the kinetic theory of crystal growth research.^[14][15] The Stranski-Krastanov growth and the Kossel-Stranski model have been named after him.
• Dimitar Ivanov Popov - Ivanov reaction.
• Dimitar Sasselov - in 2002 sighted the farthest planet from the Earth discovered until then - OGLE-TR-56b.
• Boicho Kokinov - DUAL (cognitive architecture).
